NEW Smart Tech
4R70W HD Forward Clutch Drum

 Increased groove depth for additional ring support


  • One-piece forged material provides increased strength and durability over the OE stamped drum

 

A common failure of the Ford 4R70W, 4R70E, 4R75W, 4R75E is the separation of the forward drum at the snap ring groove. The manufacturing process of the OE snap ring groove creates high-stress points around the circumference of the drum.

The forward drum is active in 1st, 2nd and 3rd gear ranges and suffers the most abuse on a forced 4-3 kick down, especially in heavy duty applications.

The concurrent pressure from the forward clutch piston combined with the high stress at the snap ring groove causes the upper portion of the drum to split and separate at the groove.

Depending on severity of breach, this can result in no forward engagement or slipping in 1st, 2nd and 3rd gear. The forged, one-piece construction of the Smart-Tech forward clutch drum eliminates weakness at these stress points.
