Updates to the Transmission
TransGo Shift Improver Kit
This Well Engineered TransGo kit replaces weak valves springs, accumulator springs, servo springs, and fixes other issues with this transmission. Overall the kit helps increase the life and durability of the transmission.
Updated Sun Shell
We use hardened spline Sunshell helps prevent stripping of where the Sunshell splines on to the rear sun gear, which is a very common issue with the OEM (GM) Shell.
Updated Accumulator Pistons
We use aluminum accumulator pistons versus original plastic pistons, or worn leaking OEM type pistons
Updated ¾ Clutch Pack
We use Alto 9 Clutch 3/4 stack up (The ¾ Clutch pack is one of the biggest weak spots of the this transmission, this ¾ stack up allows the load to be to better distributed on the increased clutch apply area of the 9 clutches instead of the 6 clutches OEM);
Reverse Input Capsule
Helps reduce premature failure in the Reverse Input Clutch.
Warranty:
This transmission comes with a 3 Year 36,000 Mile Warranty!!
