What's Included

• TCC Priority Valve Kit
• TCC Signal Damper Piston Kit
• TCC Regulator Valve Spring
• Main Pressure Regulator Valve Kit
• LPC Signal Damper Piston Kit
• Six Solenoid Stabilization Retainers
• Latch Valve Stem Repair Kit
• Technical booklet with vacuum testing and repair tips

How It Fixes the Problem

On these 10-speed valve bodies, wear in the main pressure regulator valve, TCC priority valve and TCC regulator valve lets pressure leak from the main line, TCC and clutch-apply circuits. That shows up as TCC shudder, harsh or delayed shifts and pressure complaints. The Zip Kit parts seal those circuits, the signal damper pistons steady TCC and clutch apply pressure, the stabilization retainers keep the solenoids seated, and the latch valve stem repair kit fixes the latch valves that get beaten up by the retainer clip.

Fitment

Sonnax lists this kit for Ford 10R60, 10R80 and 10R90 and GM Gen. 1 10L60, 10L80 and 10L90 valve bodies. Some later 10R80 separator plates have no hole over the accumulator lineup. If yours has no hole, the TCC signal damper piston kit is not needed. Confirm your transmission and valve body generation before ordering.
