Since its early production in 1999, the RFE platform has been plagued with many issues. Some of the biggest problems have been premature clutch failure and valve-body wear. The premature clutch failure can be isolated to hydraulic cross leaks and warped valve bodies. Approximately 80-90% of those cross leaks have been found in the OE channel plate casting.

If you look closely at the stock casting with a straight edge, you will notice that there is some severe flexing and warpage. Looking at how the valve-body is fastened to the transmission and being that there are limited contact surfaces it’s no wonder we see so many problems. For example, fourth gear clutch failure, premature valve-body bores worn, and defective valve lands.

We have noticed over the years that in many cases the same vehicle would require another new valve-body after only 60-70,000 miles. So, we decided that the best way to fix this issue was to eliminate channel plate flexing.

We developed a new plate made of billet aluminum that has shallow hydraulic circuits. It is made from a solid 1” piece of material. Machining away only what is necessary to ensure no warpage and a very solid foundation to bolt the valve body back to. Also, we have slightly moved some passages and eliminated those not necessary in hopes of stopping separator plate chafing and valve-body breakage and cracking from high line pressure in performance applications.

With our new billet channel plate, the end user is able to use the stock hardware. They can also choose whether they want to use a bonded separator plate or a good used stock one. The customer can also apply stock or performance tuning with higher line pressure with our D-CF2-2019 plate. We believe that with our plate there will be no more need in ever buying another valve body again.
