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.\u003c\/p\u003e\r\n\u003cp\u003eSonnax 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.

The RFE platform was originally designed by Chrysler and was introduced in 1999 with the debut of the new Jeep Grand Cherokee. The \"RFE\" stands for Rear-wheel drive Fully Electronic control. The RFE design was mostly noted in the new design to have 3 planetary sets for a 4-speed transmission in the 45RFE.\u003c\/p\u003e\r\n\u003cp\u003eIn 2007, Chrysler debuted the new 6.7 Powerplant in the all new Dodge Ram, and Dodge wanted a transmission that was specifically designed for function. The previous platform utilized the Torqueflite 48RE platform. The 46\/47\/48 Chrysler platforms were 3 and 4-speed units that were mechanically and hydraulically controlled, with the most notable control system being governor pressure.\u003c\/p\u003e\r\n\u003cp\u003eThe first improvement Chrysler wanted to make over the Torqueflite platform was, obviously, the amount of forward gears. For the 68RFE transmission, Chrysler opted to change to a six-speed unit. The additional gears allowed Chrysler to add higher 1st-gear ratios and tighter shift recovery from one gear to the next. The tighter shift recovery essentially keeps the vehicle in higher averaged horsepower and torque numbers, while also adding torque multiplication.\u003c\/p\u003e\r\n\u003cp\u003eThe gear ratios were increased. as well. The new 68RFE boasts a whopping 3.23:1 first gear, compared to the 2.45:1 first gear found in the previous 47\/48RE platform. Chrysler also increased second gear to a 1.83:1 versus the 1.45:1 found previously. The 68RFE was also given two overdrive gears, with 5th being .81:1 and 6th with the very deep .62:1.

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.\u003c\/p\u003e\r\n\u003cp\u003eSonnax 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.

The previous platform utilized the Torqueflite 48RE platform and had been around since the late 50's when they released the first 727 in 1956 after purchasing the license from Simpson on the gearset in 1955\u003c\/p\u003e\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003cp\u003eThe 46\/47\/48 Chrysler platforms were 3 and 4-speed units that were mechanically and hydraulically controlled, with the most notable control system being governor pressure.\u003c\/p\u003e\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003cp\u003eThe first improvement Chrysler wanted to make over the Torqueflite platform was, obviously, the amount of forward gear. For the 68RFE transmission, Chrysler opted to change to a six-speed unit. The additional gears allowed Chrysler to add higher 1st-gear ratios and tighter shift recovery from one gear to the next. The tighter shift recovery essentially keeps the vehicle in higher averaged horsepower and torque numbers, while also adding torque multiplication.\u003c\/p\u003e\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003cp\u003eThe gear ratios were increased. as well. The new 68RFE boasts a whopping 3.23:1 first gear, compared to the 2.45:1 first gear found in the previous 47\/48RE platform. Chrysler also increased second gear to a 1.83:1 versus the 1.45:1 found previously. The 68RFE was also given two overdrive gears, with 5th being .81:1 and 6th with the very deep .62:1.
