Evening, ok I have been researching and reading and need some input. I have the 700R4 in my car right now. With swapping out the engine for a more powerful one in the not to distant future has anyone had any luck with beefing up their 700R4? Is the 4L60 or 200R any better? I do like manual trans. and am not opposed to installing one, but I like an auto for this application better. Thank you for the help.

200r4 and 4L60 dont have that big jump between 1st and 2nd gear. Ive seen 700r4's hold up to 500 HP in daily drivers with a good performance rebuild and oil coolers. 4L60 hold up pretty good in High output motors. not too much exp with the 200r4

 

I have been looking at some good kits for the 700r4 that I think should do the trick then. Unless the 4L60 is that much better to start with, then I will go find a good core to rebuild. Thanks for the help!
