A904 high performance rebuild--advice wanted

Awesome info, guys. Thanks to all of you.
I'm already feeling better prepared.

Learn to do it yourself is my suggestion. For about $200 in parts you can do one at home. No need to spend a ton of money on a trans for that build.

I'm inclined to agree with you in regards to most topics...in the long run it's more affordable and more gratifying to learn these things on your own. That said, pyrojim nailed it:

I learned a long time ago that it costs me more to get stuff fixed after I fixed it. I'm a believer in "I'll do what I do for a living and let other people do what they do for a living"

My experience exactly. I'd probably make it worse. :p

If I had more time off from work or wasn't hoping to have the car on the road in the next couple of months, I'd give it a try. I know it's not magic...but I have a relatively limited space to work in, no access to a lift, still only building up my tool box.

I can see both sides...but in this case, I think it's worth my $ to let a reputable shop take care of it and I'll write the check.
