TransGo AW55-50 SHIFT KIT® Valve Body Repair Kit includes everything you need to address wear issues in the valve body, plus thorough instructions on rebuilding the control solenoids.
We know how hard it is to deal with complaints AFTER the transmission is already back in the car. This is a fine transmission with a good lifespan. Normal wear in control parts causes most malfunctions. Unless you fix this wear while you have the car, you risk a comeback or a no-ship. Replacement Shift Solenoids are available. OE Replacement Control Solenoids are NOT available separately.
Now the good news: Included in this kit, is parts with complete technical information to fix the control solenoids. We also furnished parts for the usual wear items in the valve body. Your care and patience installing this product will make this transmission a real winner! Go for it!

- Reference #
- Extra information
Lockup relay control valve kit
• Valve• SleeveAlso fits AF 23/33 and RE5F22A units.
• Sleeve is manufactured from highly wear-resistant billet aluminum.• Sleeve has been redesigned to eliminate rotational indexing issues and provide flow 360 around the valve to prevent side loading.• Sleeve design incorporates grooves and cross-slots to maximize valve support while maintaining proper flow.•Valve is made from hard-coat anodized aluminum to prevent wearSymptoms: • Inadequate lubrication• TCC apply & release concerns• TCC codesCause: A sticking lockup relay control sleeve prevents TCC apply or release. Sleeve wear reduces converter pressure, overheating the fluid, and results in bushing and solenoid failure.
Correction:
The tightly toleranced, drop-in replacement Sonnax valve and sleeve assembly restores proper hydraulic clearances, provides greater valve support, and uses upgraded materials to prevent wear.

• Valve• Sleeve• Sleeve is manufactured from highly wear-resistant billet aluminum.• Valve is made from hard-coat anodized aluminum to prevent wear.• Salvages costly cores with minimal labor.• Eliminates the need for expensive OE valve bodies.Symptoms: • 2-3 Flare• B5 Clutch distress• Engine stall on engagement• Harsh shifts• No 2-3• No lockup• Shift concernsCause: Sleeve wear affects the position of the solenoid relay valve. Complaint depends on amount of solenoid modulator oil loss and in which position that valve may seize.
Correction:
The tightly toleranced, drop-in replacement Sonnax valve and sleeve assembly restores proper hydraulic clearances and uses upgraded materials to prevent wear.
NOTE: Also fits AW55-51SN, AF 23/33 and RE5F22A units.

Boostvalvekit AW55-50
• Valve• Sleeve• Sleeve is manufactured from highly wear-resistant billet aluminum.• Valve is made of hard-coat anodized aluminum to prevent wear.Symptoms: • Delayed Drive• Delayed Reverse• Erratic Reverse pressure• Harsh upshifts• Soft upshiftsCause: The valve within the sleeve separates reverse boost oil from throttle signal (SLT) oil. Pressure in reverse can either be delayed or added to SLT, which results in very high reverse pressure. If the sleeve is worn and selector is not in Reverse, SLT is allowed to vent at the manual valve, reducing line rise, which affects engagements and shift quality.
Correction:
The tightly toleranced, drop-in replacement Sonnax valve and sleeve assembly restores proper hydraulic clearances and uses upgraded materials to prevent wear.
NOTE: Also fits AW55-51SN, AF 23/33 and RE5F22A units. The 59947-07K should not be used with Sonnax oversized pressure regulator valve 59947-12K.

Secundary regulator valve AW55-50
• Valve• Spring• Salvages valuable core.• Improved valve support to reduce wear.• Improved converter feed and lube flow.• Anodized aluminum valve replaces OE steel valve for better clearance control with the aluminum casting.Symptoms: • Harsh Reverse• High SLT pressure• Low SLT pressure• Overheated fluid, bushings & converter• Poor shift quality• TCC slip• TCC surgeCause: Bore wear at the spring end of the valve allows the SLT circuit and regulated converter pressure to cross leak. Bore wear at the balance end of the valve reduces converter and lube flow.
Correction:
Install the Sonnax Secondary Regulator Valve & Spring kit to restore hydraulic integrity to the circuit.

Spring B5 control AW55-50 [5]
Package Quantity: 5
Only some Aisin AW 55-50SN transmissions ('05-later units installed in Nissan and GM vehicles) were equipped with a control spring in the B5 clutch control valve line-up. Using a valve body without a spring in those vehicles creates a mismatch between the B5 line-up and the TCM calibration, often causing a harsh 2-3 upshift or 3-2 downshift.
Sonnax offers B5 control spring 59947-33 as a direct replacement for the OE spring. This allows rebuilders to rebuild any suitable core for use in vehicles where the spring is required, or correct shift concerns caused by a missing spring.
• Restores valve train response, matching the TCM calibration• Allows any AW55-50SN valve body to be converted to a spring type application• Direct replacement, no special tools requiredSymptoms: • 2-3 Flare• 2-3 Harsh• 3-2 Flare• 3-2 Harsh• Incorrect valve body calibration• Missing B5 control springCause: TCM programing anticipates spring control response in the B5 control line-up in certain vehicles. Without this spring, the calibration is mismatched and 2-3/3-2 shift issues may occur.
Correction:
The Sonnax B5 control spring is a direct replacement for the OE spring and it can be added to any valve body in order to match the TCM calibration.
NOTE: Also fits AW55-51SN, AF 23/33 and RE5F22A units. Only some '05-later units were equipped with a control spring in the B5 clutch control valve line-up.

Solenoid modulator valve AW5550 OS
• Valve• End PlugSymptoms: • 2-3 Flare• 5th Gear only• Delayed Forward• Low line pressure• No 3rd• No 4th• No 5th• No lockupCause: The OE steel valve results in excessive clearance during hot operation and frequently sticks when cold. Bore wear can reduce available solenoid modulator pressure, resulting in delayed forward, flare on 2-3, TCC slippage or soft shifts overall. Bore wear at the inboard end results in excess solenoid pressure, improper gear or harsh shifts.
Correction:
The Sonnax oversized solenoid modulator valve made of wear resistant hardcoat anodized aluminum re-establishes proper pressures. Additional support is given to the valve by adding length to the outboard spool.
Shift press.cntrl.v AW5550 OS
- Part #
- 59947-38K
- Reference #
- Extra information
The shift pressure control valve in Aisin AW 55-50SN units is biased by spring force and shift control (SLS) fluid pressure. This valve regulates Drive and Reverse fluid pressure to control the apply of the second clutch (B2), the second coast clutch (B1) or the direct clutch (C2).
The constant oscillation of the valve wears the cast aluminum sleeve, allowing Drive and Reverse fluid pressure to leak and cause shift complaints and burnt clutches. The drop-in Sonnax shift pressure control valve kit 59947-38K uses upgraded materials and annular grooves on the valve to correct the problem and prevent future wear.
• Valve is hardcoat anodized to reduce wear• Annular grooves on the valve hydraulically center it in the bore to prevent sleeve wear• Valve• Sleeve

Connector/clip AW55-50 [5],TF60,TF80,TR60
The Aisin AW 55-50SN and 6-speed valve bodies have a solenoid connector which breaks during wire harness removal. Once the bridge lock is broken, the wiring will not remain engaged.
Sonnax solenoid wire connector retainer 59947-60 snaps over the solenoid connection holding the wire terminals in place. The retainer can be installed without removing or rotating the linear solenoids.
• Allows solenoids with broken connectors to be reused• No special tools required• Snaps over the remaining plastic frame

Acc.piston AW55-50
• Piston• Springs (2)• O-Rings (2)•No special tools required.• O-rings eliminate fluid leakage between LPC piston and bore.• O-rings eliminate metal-to-metal contact between piston and bore that causes wear.Symptoms: • 2-3 Flare• Delayed Forward• Erratic SLT pressure• Harsh shifts• Low line pressureCause: Line pressure control accumulator pistons are leaky, jammed or bound.
Correction:
This LPC accumulator piston is made of aluminum to match the expansion rate of the aluminum valve body (OE was steel). The piston restores SLT pressure and dampening. SLT is the boost pressure in this unit.
NOTE: Also fits AW55-51SN, AF 23/33and RE5F22A units.
