When i nail the gas my RPM's shoot up, i had a gear change and thought it might be that but if its the trans slipping then ill be replacing it with something else, either a T400,T350 or maybe 700R4. I want to be able to do 80-90 on the highway without being super high in the RPM's so i want overdrive. I would also like to have the trans shift by itself, not me monkey shifting it. And i was wondering if i can keep my stock shifter. Let me know your guys's recomendations.

 

what are your mods? From what it sounds like you DO NOT want a 3-speed trans, so i would go with a 200R4 or just get the 4L60E rebuilt (cheapest)

 

sorry, ill post my mods

Long tube headers + lanes X Pipe
full ls1edit
Moser 12 bolt w/3.73 gears
F1 cam 230/226 .591/.569 112
PT4000

I was going to go with a heads and cam package but now this will delay it back a while. I dont go to the track often but i do want to make a few 10 sec passes with the new heads and cam. I also run on the street alot so i want somethin that willl hold to that abuse. Another member said i could get a T400/T350 and get a gear vendors overdrive onto it, could that be a good choice?

 

Also consider the newer 4L65E, have it rebuilt/strengthened as well.

 

I thought about it, but wasnt it only rated for not much more than the 4l60E? I am kinda weary about trying something new, i would rather go with a tranny that is proven.
