Thread: 99 gtp trans issues

Since I have to remove the valve body I figure I'll replace/upgrade the parts in there since I'm already in there, but I'm kinda hoping to limit the amount of stuff I remove since this will be my first time inside a tranny that I actually intend to put back together.

I just ordered all of my stuff last night. I'm going through it all, new seals, steels and fibers, new bands. I've seen the reverse band break on newer trans. Figured I'd might as well do it all, I don't want to have to take it back out. I don't know if there is any advantage but I'm doing it for piece of mind.

You and I think alike my friend! That's exactly what I did. Good luck!

As long as you don't have any issues now, you'll be ok to use old clutches unless your over 200,000.

For performance, a great resource is the performance rebuild dvd from ebay, had some great advice.

For turbo, personally I agree with triple edge on their approach of upgrading input shaft, pump shaft, output shaft, hd differential if you don't have one, 7/8" chain, custom torque converter, and billet flex plate. Too many people try to skimp on the flex plate and torque converter and end up kicking themselves later.

Basically, for performance, you're easily looking at $2000 just in parts, which is the only reasonI haven't gone for it yet.

This is not saying that you can't run turbo with no mods, it depends how you drive, what your performance expectations are, and how long you want it to last.
