Hey guys I have a 98 4l60e that was just rebuilt and upgraded with 2000 stall Corvette shift kit..
Now I also added the dorman 901 I Intake and 90mm throttle body and headders
So after first build got about 500 miles doing ve. And maf. Tuning them started slipping 4th then 3rd while driving.. pulled trans again and 3rd clutches smoked..
Repaired and now 1/2+ throttle starts slipping into 3rd dont want to burn it again so.... only 2 miles on it so far,
My question.. is the trans tune going to be off that much at stock trans tune to burn it up with the upgrades I did.. is there something to address first thanks for any and all ideas.
