TCC isolatorvalve 4L60E SRTA .472"
- Part #
- 4L6-ISO-3
- Reference #
- Extra information
1995 to 2015 General Motors vehicles equipped with a 4L60E, 4L65E and 4L70E SERTA (Service Replacement Transmission Assembly) remanufactured transmission often come in with complaints of TCC slip or shudder, code P1870 or P0894 and harsh 1-2 shift.
The torque converter clutch regulator valve bore is very prone to wear causing the TCC slip complaints and related code. The TCC slip code leads to the harsh 1-2 upshift as the ECM recognized the TCC slip and commands high line pressure to avoid further TCC slippage and damage. For that reason, GM remanufactured SERTA transmissions usually have valve bodies that have been machined to allow the use of a larger .472” diameter TCC regulator and isolator valve. Over time those wear out the bore the same way the originally valve did, again leading to the same complaints.
Features and benefits:
This TransGo 4L6-ISO-3 kit features a drop-in USA-made hardened steel, oversized patented isolator valve. The redesign valve restores the hydraulic integrity of the circuit by utilizing previously unused and therefore unworn areas of the bore. In addition, it can be used without the included spring to work in vehicles with active fuel management (AFM). Lastly, this kit includes enough parts to fix three transmissions.
Corrects/Prevents/Reduces:
- TCC slip or shudder
- Code P1870 and P0894
- Harsh 1-2 shift
- Reduces future wear
Includes:
- (3) Drop-in USA-made hardened steel over-sized isolator valves
- (3) Isolator valve springs
Pres.reg.valve 4L60E, 5L40E drop-in
- Part #
- 4L60E-PR
- Reference #
- Extra information
- 1993 to 2015 General Motors vehicles equipped with the 4L60E, 4L65E, 4L70E and 5L40E automatic transmissions over time wear out the line pressure regulator (PR) valve bore. As a result, in cases where the wear is most prevalent at the balance end of the valve, the pressure will be unstable. Moreover, if the wear is severe enough, it can result in unregulated high line pressure. On the other hand, in those cases where the wear is most prevalent at the spring end of the valve, the leak in that area would cause low line pressure. For the same reason, the symptoms will vary as well, ranging from harsh shifts, soft shifts, burnt frictions, overheating, to converter clutch failure. This drop-in precision USA-made steel valve is design to provide full-time line-to-lube, as well as restoring the hydraulic integrity of the circuit without the need to machine the bore. It also features longer spool lands allowing the valve to operate in non-worn portion of the bore. In addition, the longer lands distribute load over a greater surface area for increased durability. Note transmission removal is required only if unit has ISS “Input Speed Sensor” which started 2006-2007 and up. Features: Machined for full-time line-to-lube Saves replacing pump for worn bore No special tools required Corrects/Prevents/Reduces: Erratic or low line pressure Burnt 3-4 clutch Planet burn-up Overheating or burnt fluid TCC slip Includes: Precision USA-made steel oversized valve Spring seat Spring
TCC Valve 700R4

- Extra information
TCC Apply Valve Kit 700R4
- Valve Steel
- Seal PTFE
Fits non-PWM units only.
- Hardened steel valve matches OE material
- PTFE seal eliminates cross leaking of converter signal oil and converter feed oil
Symptoms: - Code 1870
- Falls out of lockup when hot
- Fluid blown out fill tube
- Lockup immediately after 2nd gear
- No lockup
Cause:
Excessive pump bore-to-valve clearance allows TCC signal oil to leak past the spool, preventing lockup or causing lockup to disengage when hot. Additionally, converter feed can leak past the excessive clearance, combine with signal oil and cause premature lockup.
Correction:
These improved TCC apply valves with PTFE seals will eliminate bore cross leakage.
WARNING:
This part only fits non-PWM units, and mismatching PWM and non-PWM valves will cause rapid converter failure.
Identifying PWM vs. Non-PWM Units
If the OE valve features double spools at the location indicated here, you are working on a non-PWM unit. If the OE valve features one spool, you are working on a PWM unit and must use Sonnax TCC apply valve kit 77805E-K. Do not rely on the OE valve material (steel vs. aluminum) to determine for whether the unit is non-PWM, as some early PWM pumps also used steel TCC valves.

TV Link
Package Quantity: 5
The TV cable synchronizes engine throttle movement with TV plunger movement. If the cable is not readjusted to ensure proper line rise, the unit may return quickly with soft shifts and a burned 3-4 clutch or band. Sonnax has designed a throttle valve link 77872-01 that is shorter than the OE, so that the installer must readjust the TV cable.
- This shortened link was designed with the carry-out unit in mind.
- Prevents unit failure after rebuild.
Symptoms: - 3-4 Band failure
- 3-4 Clutch failure
- Low line rise
- Soft shifts
Cause:
The TV cable is out of adjustment.

Oversized Throttle Valve
A low throttle boost condition is a common complaint in vehicles with a 700-R4 transmission. This loss of throttle boost oil creates poor line rise and accelerates 3-4 clutch and band failure. In late-model transmissions, the hardened steel throttle valve continuously oscillates in the cast iron valve body bore and eventually wears the three bore diameters. This wear allows throttle valve feed oil to leak past the valve spool and exhaust, resulting in a low throttle boost condition. This excessive leakage can be eliminated by installing the oversized Sonnax replacement throttle valve 77968.
Required tool:
77968-RM
NOTE:
- Not compatible with early '82-'90 aluminum sleeve units.
- It is necessary to use Sonnax reamer 77968-RM to re-qualify worn valve body bore.

Elevated Pressure Main Pressure Regulator Spring
Low spring rates, incorrect spring heights and inappropriate replacements from previous rebuilds can lead to low base line pressure. The Sonnax replacement spring 77917-08 provides a resultant idle base line pressure of 72 psi, and 82-85 psi cracking pressure, which is consistent with the OE orange spring.
Symptoms: - Low base line pressure
Cause:
Low spring rates, incorrect spring heights and inappropriate replacements from previous rebuilds.
Correction:
This replacement spring provides a resultant idle base line pressure of 72psi, consistent when compared to the OEM orange spring.
NOTE: Low line pressure resulting from worn boost valves, a worn pump bore at the pressure regulator valve or pump pocket wear will not be corrected by this spring.

Pump Slide Spring
Package Quantity: 5
We now offer a high performance pump slide spring 77722-01K for the 4L60, 4L60-E, 4L65-E and 200-4R. In high performance applications, when engine speed exceeds 5800 rpm, the centrifugal force on the pump vanes acts to center the pump slide and reduce the pump volume. In high performance applications it is critical to maintain maximum pump volume in order to hold line pressure and avoid 3-4 clutch failure. The Sonnax spring is stiffer than the combined force ofthe dual OE springs and is able to hold the pump slide in a maximum volume position despite the high engine speed.

- Does your TH-700-R4 or 4L60E transmission have a worn out and damaged valve body spacer plate? The Accumulator frequently destroys the valve body separator plate. At least four plates need to be stocked for coverage and the new plate is no better than the old one. Solution: Don't waste money on a new plate, because you can easily repair your valve body separator plate with the Heavy-Duty heat-treated steel Corner Plate (inserts in between the accumulator cover and valve body plate ).

Plug 4L60E Forw/Rev abuse plug
- Part #
- 77754-21
- Reference #
- 74741
- Extra information
Forward & Reverse Abuse Bore Plug
Fits in either of two locations
The bore plug in 4L60-E units is held loosely in place with a coiled spring pin, allowing the opposing spring and oil pressure forces to stroke it within the bore. This constant oscillation causes the plug to wear and allows PR oil at the low overrun valve and 3-4 clutch oil at the 3-2 downshift valve to exhaust at the abuse valves. This excessive oil loss can result in delayed apply of the low/reverse clutch and a tie-up of the 3-4 clutch and 2-4 band.
This plug is used in two locations in the valve body: to separate the forward abuse and low overrun valves, and to separate the reverse abuse and 3-2 downshift valves.
Symptoms: - 2-4 Band burned
- 3-2 Bind-up
- 3-4 Clutch burned
- Burnt Low/Reverse clutch
- Delayed Reverse
Cause:
Wear of the bore plug in the forward and reverse abuse valve bores can allow valuable oil pressure to exhaust.
Correction:
This increased diameter plug restores proper clearance in the valve body and requires no tools for installation.

The 3-2 control valve spring in late-model 4L60-E and 4L65-E valve bodies often breaks, and can cause a 3-2 bind and/or 2-4 band to overheat. This spring is often found to be broken during valve body service, and OE replacements are not available.
NOTE: This spring works only in '96-later on/off- style 3-2 control valve bodies. It will not work in 1993-95 PWM-style 3-2 control valve bodies.
Symptoms: - 3-2 Bind-up
- Broken 3-2 control valve spring
- Overheated 2-4 band
Cause:
Fatigue from 3-2 control valve operation.
Correction:
Replacement spring salvages valve bodies and prevents 3-2 bind or 2-4 band overheat.

This kit fits either the forward or reverse abuse location and includes a replacement bore plug.
Symptoms: - Damaged valve body casting
- Delayed Forward
- Delayed Reverse
- Forward or Low/Reverse clutch distress
- Low line pressure upon engagement
Cause:
The OE valve is subjected to high side loading, which wears out the bore and reduces pressure to the clutch.
Correction:
The Sonnax drop-in replacement valve is slightly oversized, has extended spool lengths, stabilization flats, annular grooves and a reduced spring load. This valve eliminates clutch pressure loss as well as continued bore wear. One valve and spring work for either the forward or reverse abuse location.

Heavy Duty 2-3 Shift Valve
Sonnax has developed a drop-in replacement 2-3 shift valve that applies the overrun clutch in D3, 1st, 2nd and 3rd gears where the factory valve applies the overrun clutch only in D3, 3rd gear.
Applying the overrun clutch in 1st and 2nd provides added durability to the input sprag and forward clutch in heavy duty vehicles, plow trucks and high performance applications.
In addition, this upgrade works well with applications using aftermarket electronic paddle shifters. With the overrun clutch on, the Sonnax valve allows full downshift engine braking in 2nd, while the shifter remains in the D3 position.
- No special tools required
- Extends life of the forward clutch and input sprag
- Ideal for electrically downshifted units with aftermarket paddle shifters

- Heavy Duty 3-4 Clutch Backing Plate Kit Part No. 74140-01K Requires ‘91-later 3-4 apply ring stamped with number “7”, measuring 3.671–3.682" in height. A thin, weak backing plate is the leading cause of 3-4 clutch distortion and burnup – a pervasive problem in listed GM transmissions. Even the thickest OE backing plate flexes during clutch apply, allowing heat to build up unevenly, causing problems in daily drivers and mid-level street/strip vehicles alike. Other aftermarket solutions typically employ a thinner backing plate, and thinner steels which ultimately exacerbate the problem. Sonnax heavy duty 3-4 clutch backing plate kit 74140-01K significantly reduces backing plate flex for increased 3-4 clutch durability. It features a significantly thicker and stiffer backing plate, used together with a thinner (yet stiffer) apply plate. Designed for use with GM high energy clutch pack with seven .067" frictions and six .095" steels, this kit can be used to upgrade OE 700-R4 and 4L60-E five-friction or six-friction clutch packs to seven frictions, or to improve stock, seven-friction clutch packs in 4L65-E and 4L70-E units by reducing backing plate flex. Backing plate is significantly thicker and stiffer than OE for added durability Drop-in, mid-level upgrade for daily drivers and mild street/strip applications Contents Backing Plate Apply Plate

In 200-4R applications, this kit can only be used in the 3-4 accumulator location.
In GM 200-4R, 4L60 and 4L60-series units it is common to have poor shift quality, burnt bands or clutches due to accumulator piston wear. Repeated reciprocation of the accumulator piston causes wear at the piston pin bore interface. After this wear reaches a critical point, fluid loss through the piston pin bore cannot be compensated due to lack of pump volume. In addition, the piston can get cocked and gall the accumulator bore due to the pin bore wear or the spring bottoming out. To prevent these conditions in the 1-2 or 3-4 accumulator bores, Sonnax offers pinless accumulator piston kit 77998-03K.
Symptoms: - Burnt clutches & bands
- Poor shift quality
Cause:
Wear at the piston pin bore due to repeated reciprocation.
Correction:
The Sonnax patented pinless design with dual seals stabilizes the piston in the bore and provides improved sealing characteristics. Use of the Sonnax part eliminates the need for the pins.

Piston Forw.4L60E Billet Aluminium
The OE cast aluminum forward piston frequently breaks due to rough castings and high stresses. This billet aluminum forward piston eliminates these concerns by using high strength billet material and a design with added contours in the high stress areas. No machining or modification is required to use this piston and it can be used in all 4L60/4L60-E/4L65-E as long as it is used in conjunction with an aluminum over run piston.
- Eliminates concerns of forward piston breakage.
- Improved durability and strength over the OE's cast aluminum forward piston.
- Can be used in both early and late model transmissions.

• Heavy Duty Reaction Shell• Enclosed Thrust Bearing• Custom Roller Clutch RaceIn GM 4L60, 4L60-E, 4L65-E and 4L70-E units, bulky aftermarket shells always fall short when splines continue to strip and the shells break under stress. A chronic problem with both OE and thicker aftermarket shells is failure of the rear planetary bearing.
From daily jobs to extreme builds, the Sonnax SmartShell heavy-duty reaction shell kit 77749-02K is the only way to prevent shell failure AND protect the bearing.
The SmartShell avoids the weight found in traditional, heavy-duty aftermarket shells thanks to a unique combination of improved design and manufacturing for a super strength shell that's only slightly bulkier than OE.
To prevent thrust loads from overwhelming the captured planetary bearing, the SmartShell features a larger bearing and custom roller clutch race. These parts re-route thrust loads through the carrier, completely bypassing the delicate bearing.
• Stops spline stripping• Prevents hub breakage• Eliminates planetary bearing failure

The 3-4 accumulator bore on GM 4L60 and 4L60-E series cases can become scored, resulting in the loss of 4th servo feed and 4th accumulator pressure. Scoring is caused by repeated oscillation of the accumulator piston within the bore during normal operation. Once this bore is damaged the case must be scrapped. Sonnax 3-4 accumulator sleeve kit 77998-01K conteracts bore wear and features upgraded materials for greater durability. The kit's piston is compatible with all OE accumulator springs.

A burnt band on the GM 4L60, 200-4R or 325-4L transmission can be created by accumulator cross leaks. A driveability complaint of 2nd gear starts or 2-3 bind-up can result from excessive piston wear. These complaints can be caused by oil cross leakage between the piston and pin in the 1-2 and 3-4 accumulators. This is due to the constant oscillating motion of the aluminum accumulator pistons on the steel pin.Band apply pressure is simultaneously sent to the accumulators and band.
The problem occurs when accumulator control oil and band apply circuits cross leak. Accumulator control oil will bleed into 2nd apply or 4th apply and drag the band/clutch due to imbalanced oil circuits. Ream the bore and install Sonnax oversized accumulator pin and reamer kit 77999 to resolve these problems.
- The working diameter of the Sonnax pin is slightly oversized, allowing the bore of the accumulator piston to be modified to restore the hydraulic integrity of the assembly
- Eliminates the need to replace the expensive accumulator piston, and is more durable than a bushing

Accumulator pin Oversized 4L60E [4]
Package Quantity: 4
A common condition in 4L60-E transmissions is a burned forward clutch or delayed engagement. A worn forward accumulator piston pin bore is frequently the source of this condition. The aluminum piston continuously oscillates on a hardened steel pin, which can cause wear resulting in forward clutch oil exhausting. This oil loss reduces accumulator action and decreases the forward clutch apply pressure. The replacement oversized accumulator pin 77754-01K eliminates this problem.
Symptoms: - Burnt Forward clutch
- Delayed engagement
Cause:
A worn forward accumulator piston pin bore.
Correction:
This oversized replacement accumulator pin restores the proper fit between the piston and the bore and allows re-use of the original aluminum piston.

TV Cable Corrector Kit
Part No. AS1-01KIn most GM and Ford transmissions with cables, including GM TH200, 200-4R, TH200C, 4L60 (700-R4) and Ford AOD, AXOD, the throttle valve cable pulls out of adjustment at wide-open throttle. This is typically caused by inaccurate geometry of the throttle shaft lever. There should be a specific degree of movement of the attachment element pivot point between closed and wide open throttle. There also should be a specific distance between the pivot points of the attachment element and the throttle shaft lever. When either of these two distances are greater than the spec, the TV cable will be pulled out of adjustment.
Sonnax TV cable corrector kit AS1-01K prevents the TV cable from being pulled out of adjustment at full throttle by allowing the spring to compress and absorb any excessive cable pull. A quick and inexpensive fix for any transmission with a TV cable.

It is common for one of the three plastic retention tabs to break on the wiring harness case pass-through connector. This allows the connector to be pushed into the case when connecting the external harness. Not only does this require extra labor to fix, it also requires a new wiring harness. Sonnax has now developed two wiring harness connector brackets to retain the internal harness connector even though the retention tabs may be broken: 77980-01K for the 4L60-E, and 34998-01K for 4L80-E units with late-style gray connectors only.
- Brackets firmly hold the connector in place from inside the pan using existing hardware.
- Connector brackets save expensive wiring harness replacement.

2nd Gear Servo Release Technicians would like to find a way to successfully extend the life of 3-4 clutches, and improve the 2-3 shift feel. They have been trying, with limited success, since the GM 4L60 (700-R4) and 4L60-E series transmissions were introduced. Inadequate metering of 2nd gear band servo release oil causes 3-4 clutch failure. The 3-4 clutch and 2nd gear band are not properly synchronized. Sonnax servo release check valve kit 77701-076 is a unique solution that combines an orifice with a ball check valve to resolve these problems.
•Improved design meters servo release oil, reducing 3-4 clutch failure
•Provides sufficient exhaust so that 3-2 downshifts are smooth
•Calibrates 3-4 clutch feed orifice without creating shift concerns

Part No. 4L60E-LB1Early-style "long" boost sleeve, 1.907" length.
Line pressure booster kit 4L60E-LB1 fits early-style GM 4L60-E, 4L65-E and 4L70-E pumps. Sonnax hydraulic line pressure booster kits contain stronger pressure regulator springs and large ratio boost valves designed to work together to provide progressive pressure increases as driving conditions become more demanding.
Our pressure regulator springs are approximately 10% stronger than OE and more conservative in impact than other aftermarket kit springs. Large ratio boost valves provide higher pressure incrementally and when it is needed the most. The combination of these springs and valves in a Sonnax kit gives you the best of both worlds: a modest pressure increase at the low end, with a high-end pressure that is equal to or greater than that of other aftermarket kit springs.
- Achieve shorter shifts and increased torque capacity without creating low-speed harshness
- Improved band and clutch holding capacity for increased durability
- Progressive pressure increase as driving conditions become more demanding
- All the benefits of increased line pressure without overloading the pump at idle
- Simple and affordable drop-in solution with no special tools or reaming required
Replaces early-style boost valve with "long" 1.907" sleeve. For applications with "short" 1.810" sleeve use 4L60E-LB2. See instructions for additional application information.
