The Solution for Overdrive Clutch Failure — Proudly Made in USA!

Per the awesome folks at DNJ Components:

Since its early production in 1999, the RFE platform has faced issues like premature clutch failure and valve body wear. These problems often stem from hydraulic cross leaks and warped valve bodies—especially in the OE channel plate casting.

Stock castings show severe flexing and warpage, leading to fourth gear clutch failure, worn valve body bores, and defective valve lands. Many vehicles require a new valve body after only 60–70K miles.

To solve this, DNJ developed a billet aluminum plate with shallow hydraulic circuits, machined from a solid 1” block. It eliminates warpage and provides a solid foundation for valve body mounting. Passages were adjusted to reduce separator plate chafing and valve body cracking under high pressure.

This billet plate works with stock hardware and allows use of either a bonded separator plate or a good stock one. It supports stock or performance tuning with higher line pressure using the D-CF2 plate—eliminating the need to ever replace the valve body again.

Durability Testing:

• Stock plate warped to 0.168" and cracked at 300 lbs of pressure
• DNJ billet plate flexed only 0.021" at 2 tons
• At 5 tons: 0.047" flex
• At 10 tons: 0.160" flex, recovered to 0.056"
