Valve Kit,Torque Converter Clutch Regulator/Isolator, 98-Up &EC3 Units

The OEM valves on 4L60-E units wear the bore, creating pressure leaks that affect performance. The Sonnax TCC regulator valve kits allow you to restore hydraulic integrity without replacing the bore.

Features & Benefits

Kits include a highly wear-resistant aluminum regulator sleeve to provide full support for the valves.
Anodized aluminum valve has an annular groove for better valve centering within the sleeve.
The isolator valve has been lengthened to operate in unworn portions of the bore, and also has annular grooves to prevent sideloading.
There are two options available: 77754-03K for PWM and non-PWM units, and 77754-04K, which can be used in these as well as EC3 units.
Wear-resistant aluminum isolator sleeve is available separately.
Reamers allow GM-serviced or remanufactured valve bodies to accept kits.
