Jerico upgrade
 
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?

I ran Jerico stuff for 18 years had 3 different transmissions in those years. But once the motor power went up they just couldn’t handle it. I went to a Liberty it’s been flawless and it’s the best shifting transmission I have ever shifted. I to had trouble with the jerico 18 spline input. But the 18 spline Liberty has worked without trouble.

I got rid of my Jerico stuff in 2013. Went Liberty. Best trans I've ever ran. Never let me down after 100s of runs.

If you are going to go with an upgrade, go for a much stronger clutchless set up. Stay away from the split slider set ups.

Gforce makes a true clutchless trans, a gf2400 four speed. I am sure it is good.

Liberty equalizers are also a true clutchless and I have run one for several years.amd love it.

Jim,

Liberty's clutchless is the way to go, we switched back in 2011, best move I ever made. My son in the Sunfire has had some issues with sliders with the 4 speed. I have only messed up 1 slider in the 5 speed.

Never broken any gears or twisted any shafts.

Liberty is the best trans on the planet period end of story. After I put one in my Chevy II all I could say is why didn’t I do this 10 years ago. Buy a Liberty and never look back!
