Accumulator Piston 45RFE, 68RFE
- Part #
- 44894-01K
- Reference #
- Extra information
- Accumulator piston scuffing and bore wear are common issues in Chrysler 45RFE, 545RFE, 65RFE, 66RFE and 68RFE valve bodies, especially when running increased pressures. The OE accumulator pistons have two seal rings. The seal groove at the open end of the piston is a larger diameter, with the seal ring acting as a guide to prevent piston-to-bore contact.The seal groove at the closed end of the piston is a smaller diameter and the seal ring acts as a conventional seal. However, due to the smaller seal groove diameter, the piston will contact the bore when side-loaded resulting in scuffing, wear and leakage of clutch apply pressure.Sonnax accumulator piston kit 44894-01K features two guide seal rings, one at each end of the piston to prevent piston-to-bore scuffing when side loaded. Additionally, the oil sealing ring location is relocated on the piston allowing it to run in an un-worn portion of the bore enabling bores with moderate scuffing to be salvaged. Manufactured from 6061 billet aluminum, these pistons will upgrade late model applications with plastic pistons to prevent transmission failure due to piston breakage.• Dual-guide seals prevent piston-to-bore scuffing
• Updated seal location allows use in scuffed bores
• Prevents transmission failure from broken plastic pistonsContents• Piston• Guide Seals (2)• Seal, scarf-cut

Chrysler vehicles equipped with 45RFE, 545RFE and 68RFE transmissions often show up in the shop with TCC related troubles. These concerns may include trouble codes accompanied by TCC slip, no lockup, overheating and loss of fuel economy. In some cases, the TCC may be unable to release, resulting in improper lockup and engine stall. Problems such as these are often caused by excess wear in the TCC switch valve bore, which allows vital control pressure to escape the circuit. Reconditioning the bore and installing Sonnax oversized TCC switch valve kit 44912-08K restores crucial clearances for renewed TCC control and operation.
- Lengthened critical spool provides added stability and wear prevention
- Hardcoat anodized aluminum valve combats premature wear
Symptoms: - Engine stall
- Loss of fuel economy
- No lockup
- Overheating
- TCC apply & release concerns
- TCC codes
- TCC lining failure
- TCC slip
Cause:
Bore wear at TCC switch valve allows critical fluid loss that prevents proper TCC operation.
Correction:
Eliminate bore wear and renew TCC action by reconditioning the bore and installing Sonnax oversized TCC switch valve kit.

- F-44912-TL10
- VB-FIX
Vehicles equipped with Chrysler 45RFE, 545RFE, 65RFE, 66RFE and 68RFE transmissions can develop erratic or high line pressure due to excessive wear in the OE pressure regulator valve bore. This wear allows critical oil loss, preventing correct line pressure regulation. Without adequate balance oil pressure, the PR valve will be out of its desired position, resulting in line pressure instability and possibly restricting cooler and lube flow. A deteriorated bore can cause lowered line pressure, resulting in soft shifting and burnt clutches. Reconditioning the bore and installing Sonnax oversized pressure regulator valve kit 44912-10K restores pressure regulator action for line pressure control in all ranges.

- Regulator Valve Part No. 44912-17K Vehicles equipped with Chrysler 45RFE, 545RFE, 65RFE, 66RFE and 68RFE transmissions can develop low cooler flow at idle and/or overheated fluid issues after performing aftermarket re-programming or 'tuning' the PCM/TCM for heavy duty use. Aftermarket programming typically commands a minimum of 100 psi at idle. When the pressure regulator valve is in this position the valve can restrict the connection to the converter circuits, resulting in low cooler flow, fluid overheating and converter crowding that can cause engine stall at idle. Installing the Sonnax drop-in lube regulated pressure regulator valve 44912-17K restores the fluid connection to the converter circuit at idle, which is especially important on tuned vehicles. This valve has an internal check valve that ensures proper converter and lube oil flow under extreme 'tuned' operating conditions, eliminating the fluid overheat and converter related engine stalls at idle. This check valve reseats properly to seal the converter at engine off, eliminating the delayed engagements and converter drainback issues that arise from the outdated technique of drilling a hole in the casting wall between line and lube circuits. Hardcoat anodized aluminum valve combats premature wear Charges the converter/lube circuits at low RPM, especially important in 'tuned' vehicles Improves converter feed/lube oil flow at critical low RPM and high load conditions Redesigned valve prevents fluid drainback & slow engagements Annular grooves help center valve in bore to reduce side-load wear Drop-in Zip Valve™ parts install quickly and easily

- Extra information
- The 4C return spring retaining ring in Chrysler 45RFE, 545RFE, 65RFE, 66RFE and 68RFE transmissions is known to come unseated and pop off, resulting in transmission failure. To repair and prevent this problem, plus more easily tune 4C performance, Sonnax offers 4C retaining ring and shim kit 72978-01K with three essential parts for a reliable build. The custom G-Loc ring in the Sonnax kit mechanically holds the OE retaining ring in place to prevent it from popping out. The kit’s .078" thick clutch backing plate retaining ring makes it easier to achieve the 4C clearance specification of .030 to .055". Setting this clearance is difficult when OE selective backing plate retaining rings are not readily available. As a result, some builders use thinner steel plates, but this undermines the clutch pack’s ability to dissipate heat. The ring in the Sonnax kit is .010 " thinner than the ring most units have from the factory, allowing for more choices when setting clutch clearance. The spring pack shim in the kit gives the option slightly tune the 4C clutch to release more quickly. Combining the shim with the thinner backing plate retaining ring and setting clearance closer to the high end of spec will preload the return spring for increased force. The result is improved 4C to OD shift timing when more aggressive, quicker-applying OD clutch packs are used. Prevents 4C return spring retaining ring from popping off More options when setting clutch clearance Improves 4C to OD shift timing

The shuttle plugs are prone to create bore wear and complaints and associated codes. The purpose of the solenoid switch valve and the two independent shuttle plugs is to allow one single PWM type solenoid that is designated “Low Reverse-Converter Clutch” to perform two separate functions. When the solenoid switch valve is latched in its outboard position, the LR/CC solenoid controls the oil flow to the low and reverse brake for 1st gear. On the other hand, when the solenoid switch valve is latched in the inboard position which is 2nd gear and all ranges beyond the LR/CC solenoid now controls the converter clutch. The first complaint occurs when contamination is present. This often causes the valve to stick in its bore resulting in limp-in mode and is accompanied by code P1776. Limp-in mode is 2nd starts with no upshift on the four speed models. Alternatively, a 1-4 shift strategy is limp-in mode on the rear wheel drive six speed models. Overdrive clutch failure and P0871: The second complaint with this switch valve and shuttle plug assembly is not as evident. It is the dreaded overdrive clutch pack failure that is accompanied by the trouble code P0871. The solenoid switch valve itself only strokes one time between 1st and 2nd gear. It’s in the outboard position for 1st gear and then strokes to the inboard position for the remaining forward gears. The two shuttle plugs that share one portion of the bore with the solenoid switch valve (larger end) is where the activity and wear is happening once the transmission has shifted into 2nd gear. Consequently, the shuttle plugs will wear out their independent area of the bore where they ride while the switch valve area of the bore remains in good condition. When driving in 1st or 3rd gear, oil pressure goes between the solenoid switch valve and the most inboard shuttle-plug to keep the switch valve latched in its inboard position. However, with a compromised bore, pressure can cross leak around the inboard plug and into the overdrive clutch oil circuit, partially applying the OD clutch pack when it should be fully released. The consequences of this leak around the shuttle plug is the OD clutch will be dragging ON, which eventually leads to OD clutch friction plate failure. This leak will feed enough pressure to the OD circuit to close the OD pressure switch which should remain open until the OD clutch is commanded to apply. With the OD switch closing when it should be open, the computer trips the code P0871 (overdrive pressure switch rationality). Features and benefits: The TransGo switch valve kit includes a redesigned precision USA-made steel valve with a spring pocket at its inboard end. The kit also includes three oversized steel shuttle-plugs. These components restore the hydraulic circuit integrity eliminating the Overdrive clutch drag and the P0871 code.

Line Pressure Booster Kit Part No. RFE-LB1 Fits gas and diesel units.
Chrysler RFE transmissions have a unique, full range pressure transducer and real-time adaptive closed-loop pressure control system. Because of this, it is not possible to raise pressure in an RFE the same way you would in other transmissions.
The typical method of installing a stronger pressure regulator spring or larger boost valve will not work because the RFE control module will simply adapt and return pressure to OE specification. An electrical booster option is the only way to raise pressure on an RFE. Sonnax line pressure booster kit RFE-LB1 is an improved design over a simple resistor circuit.
Featuring an integrated chip (IC) circuit and a stronger pressure regulator spring, this new kit delivers 10 psi increase at lower pressure range and 25 psi increase at higher pressure ranges. Only Sonnax line pressure booster kits provide progressive pressure increase which gives you smooth engagements and lower load on the pump at idle, but a greater increase in pressure as the transmission is worked harder.
To find out more about how the kits work, and what results you can expect, see Achieving a Progressive Pressure Boost in RFEs. This kit is ideal for heavy duty and modified vehicles and even stock transmissions when a little extra pressure is desired.
• Achieve shorter shifts and increased torque capacity without creating low-speed harshness
• Improved clutch holding capacity for increased durability
•Progressive pressure increase as driving conditions become more demanding
• One kit fits both gas and diesel applications

- Chrysler RFE transmissions use a pressure transducer to monitor line pressure. It is common for the harness-side electrical connector to break or for the pins to corrode, resulting in line pressure problems and trouble codes. Sonnax RFE transducer connector RFE-RC1 is an OE-style replacement that is equipped with a pigtail for trouble-free splicing.

Dodge trucks pulling heavy loads or boosted to 400–600HP are at high risk for Overdrive burnup due to the stock transmission’s insufficient clutch capacity and fragile OE clutches.Even small amounts of heat and extra torque will push the thin (.034"), single-sided clutches over the edge, distorting the clutch pack. The fact is, any distortion of the clutch pack takes the clearance out of spec and makes overdrive clutch burnup inevitable.Keep hardworking trucks on the road with the Sonnax Smart-Tech® overdrive clutch housing kit 72960-06K.The unique billet aluminum housing holds a physically taller clutch pack and increases OD apply area by 16%. Plus, 2X thicker clutches increase clutch pack steel mass by 28% for unrivaled heat dissipation.This groundbreaking new kit is the only top-of-the-line upgrade that eliminates clutch problems without relying on valve body/pump modifications or adding the expense of extra components.Modified housing holds physically larger clutch pack for 20% more clutch capacity
2X Thicker steels and double-sided clutches increase steel mass by 28% for unrivaled heat dissipation
Bolt-on anchor plate eliminates clutch pack flexing and distortion that contribute to heat build-up 16% More OD apply area for firmer, more controlled shifts
Combine with Sonnax line pressure booster kit RFE-LB1 for even higher levels of performance.
WARNING: This kit requires use of the input clutch retainer found in '07-later units (OE part number 04799648AB). All 68RFE, 66RFE, 65RFE should have this retainer. For 45RFE and 545RFE '99-'06 applications, the input clutch retainer must be replaced with '07-later version. See instructions for retainer identification and verification measurements.
