Sonnax 77917-04K, 700R4 / 200-4R TV Mega Boost Valve Kit
Includes:
- TV Boost Valve
- TV Boost Sleeve
Size: .500 of an Inch, Factory-Style sleeve (no O-rings).
A common problem in 700-R4 transmissions is burned bands and/or 3-4 clutches. This failure can be reduced by eliminating throttle boost oil leakage.
The Sonnax replacement assemblies 77917-02K, 77917-03K, and 77917-04K eliminate these problems.
- TV boost valve and sleeve are manufactured from hardened steel for better wear resistance.
- Kits available in three sizes for .423″, .471″ and .500″ diameters.
