I was looking at your stage 3 4L60, what is the difference between the whole tranny and the stage 3 pro-kit? What would be the core charge on this tranny? and last does the stage 3 pro-kit come with a trans-go shift kit?

 

Prices have changed, the mechanical diode is no longer available. The complete kit sells for about $450.00. The transmission (top of the line) sells for $1350.00 outright (includes core) and comes with a one year warranty. The (1988-1992) transmission comes with a Perormance Trans-Go Shift kit, new rear planetary, new late design sun shell, machined front pump, hand picked reverse input drum, turbulator low drag steels in the reverse input drum & low/reverse clutch packs, etc., and any other hard parts necessary during the performance buildup. The hard parts that come in the kit are, new stator support, rotor/ slide/ vanes/ rings springs, latest Borg Warner design front & rear sprags, etc.
Hope This Helps!!!
