Question for stick racers.
What would be the next best upgrade if replacing a jerico 4 speed for a super stock car. Although this trans has held up well I feel I may be at the limit as to what this trans can handle. Broke a shift finger and replaced that and they now have a brace which ties 1-2 and 3-4 together which so far so good. 3rd gear shows wear prob. from burnout.
Now have a slight twist and runout on the 18 spline input.
I imagine a higher spline count could help that.
Is G Force the next step or step all the way up to a $$Liberty?
