Updates to the Transmission:
- Updated Sun Shell
A chronic problem with both OE and thicker aftermarket shells is failure when splines continue to strip or the shells break under normal conditions. Use of a updated hardened spline sun shell helps prevent. - Updated Accumulator Pistons
It is common for the plastic accumulator piston to wear or crack and older aluminum piston bores to wear from repeated reciprocation. This causes a loss of fluid, resulting in delayed engagement, slips, burnt clutches and/or bands. The Updated aluminum accumulator pistons eliminates the cracking problem and restores hydraulic integrity at the pin bore. - Updated 3/4 Clutch Pack
Updated alto 9 clutch 3/4 stack up helps correct one of the most common weak spots of the this transmission, the 3/4 clutch pack. This updated 3/4 stack up allows the load to be to better distributed on the increased clutch apply area of the 9 clutches instead of the factory 6 clutches. We also use a late model 3/4 clutch one piece apply plate to help prevent warping of the the clutch pack; - Updated Reverse Input Capsule
The updated reverse input capsule helps eliminates premature failure in the reverse input clutch by controlling bleed off. Reverse clutch premature failure
