I got a stock tranny, with 60lb vavle springs and no fuel plate with a 4in straight pipe exhaust and intake and a lock up torque converter switch. I dont have any problems, Im also not a heavy footed guy. 1st and 2nd do slip to much for my liking, but i thinks thats cause i got 37 tires and 3.55 gears with a stock tranny. when i had smaller tires it had way less slip.

Mine started slipping with just a #6 plate in stock position and a boost elbow. Everything else was stock.

My auto tranny is stock.I've got the banks twin ram,duel 4" turbo back exhaust,tripple pod gauges,tranny,boost,egt.BD torque lock,afe stage 1 air filter,htt 3 piece exhaust manifold,rear suspension air bags,ect. my tranny slips a little in overdrive if i get into it,but if i don't,it's fine.Stock trannies can only take so much of a power increase.

Okay so how much over stock could I potentially go?. Im not trying to get crazy I really only want to do my fuel plate? and would yall know about the gain I would get from doing a stock fuel plate slide? the only mods I got right now are S&B full intake, and this weekend will be doing a stright 3". Im trying to get as much info on this Fuel plate and star wheel as I can before I do it. and im also going to wait tell I get gauges. But any help is greatly usefull. Thanks guys...

I seem to remember reading somewhere that The stopping point for the stock auto was a 60 horse increase. My 96 was ok with the fuel plate forward , and the afc adjusted. I installed a valvebody when I installed the tst #5 plate , and had no problems with it , and I towed and had somewhat of a heavy foot.

Any stock trans is prone to fail without mods let alone with.

Autos can fail with the stock HP never mind modded. My clutch was slipping within a month when I got mine.
