YEEEEARS ago.. my 98 GTP went through 4 stock trannys covered under warranty in a 2-3 year period.
Only mods back then was 3.4", intake, ubend removed.. maybe rockers. Car was only the mid to high 13's.
Some of them would last a few months and only a few dozen runs at the track.
They would go bad while driving down the road or leaving from a stop and something would snap inside.
None of them blew a diff. Always bands and clutches just going to hell.
My PRJ trans got me about 6-7 years of use before started to show some slipping.
