RFE Production Years: 68RFE (2007-2018) 545RFE (1999-2011) 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 cha
