The 68RFE
 
The 68RFE transmission is the big brother to the 45/545RFE transmission. 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. 
 
In 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 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. 
 
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.
 
The 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.
 
The 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 predecessor had a single overdrive that was a .69:1.
 
The Category Kits
 
The SunCoast Category 68RFE transmission rebuild kits are designed and developed with intentions of taking a systematic approach to solving the issues with the 68RFE transmission.  We approach each deficiency and need from a scientific approach.
 
These kits offer you the same recipes that are used in our facility. We aim to offer you the most complete series of 68RFE rebuild kits available on the market today. 
 
The 2C Piston
 
The factory molded piston is prone to uneven apply which leads to excessive heat in the clutches and steels creating premature failure. In this 68RFE transmission rebuild kit we replace the factory piston with a much improved billet piece that also allows for one additional clutch further increasing surface apply area. This new billet apply pistons corrects these issues and adds matched performance.
 
The Solenoid Repair and Spacer Kit
 
The factory 68RFE transmission is known for giving false pressure switch codes. These false 68rfe pressure codes some times are the result of circuit board flexing. The 68RFE transmission solenoid block can very easily be rebuilt with this Sonnax kit. This 68RFE transmission solenoid repair kit uses both a spacer to stop the circuit board flexing and improved sealing components to prevent leakage.
 
The plate to serve on
 
There factory 68RFE transmission accumulator plate is very weak and not held securely. This problem becomes even more apparent with the addition to higher line pressure which is a very common modification performed on the 68RFE
 
These new 68RFE transmission rebuild kits are designed with the builder in mind, we offer from mild to wild depending on what your needs are.
