Easy Pressure Switch Rebuilds for 6L- & Gen. 1 6T-Series Units

Presented by Sonnax

GM 6-speed transmissions often set various trouble codes caused by fluid pressure switch failure. Replacement of the expensive TEHCM in which the switches live was traditionally the only way to restore normal shift operation, but now there’s a better alternative: rebuilding the switches.

Sonnax's patent-pending rebuild kits for 6L-series and Gen. 1 6T70, 6T75 units contain exactly the right tools and parts for fast, safe installation of new pressure switch laminate discs and seals. There’s no coaxing, no practice, just successful switch rebuilds the first time, every time.

Watch the video to learn how this simple, affordable technique will save you hundreds of dollars and keep the TEHCM out of the boneyard!
