45RFE / 545RFE / 65RFE / 66RFE / 68RFE Automatic Transmission Sonnax Accumulator Piston Set and Plate Repair Kit 1999-On Includes: Pistons (5) Guide Seals (10) PTFE, Solid Seals (5) PTFE, Scarf Cut Accumulator Plate Accumulator Shim Screws (6) Washers (6) Accumulator Piston 5-piece Set 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. Each piston in the Sonnax accumulator piston kit 44894-01MK 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 pistons Accumulator Cover Plate The accumulator plate in Chrysler 45RFE, 545RFE, 65RFE, 66RFE and 68RFE units is weak and not held securely enough to withstand the impact of the accumulator pistons. The OE plate flexes, causing the screws to loosen and break. Sonnax accumulator cover plate kit 44892-01K is an upgrade over the OE plate and allows salvage of valve bodies with damaged plates. The patented plate is made of thicker steel and has three additional screw holes to hold the plate more securely. Accumulator plate made from stronger, thicker material to prevent flexing Three additional mounting holes and high torque-rated screws prevent the plate or screws from coming loose from normal vibration Specially graded tap provides higher torque yield threads ________________________________________ Save a bundle here over the cost from a dealership.
