Transmission Rebuild

[mattfleming]

Okay.. I have a 90GT with the T5. Second gear is shot and im going to have to put a ring gear on the flywheel while im down there. The question is who makes the best and most comprehensive rebuild kit? I have been looking at the D&D performance kit and the Hanlon Performance kits. How are they? What additional parts might i need? what about gaskets?
can any of you who have rebuilt or have had rebuilt chime in for me?

I just went with the super duty rebuild kit from summit racing.

A T5 rebuild kit with syncros, bearings and other small parts costs about $160. It does not include any gears or shafts.

Hanlon also has a video on how to rebuild your T5 or Tremec. If they are out of stock see http://cartapes.com. It costs less than $20, and is worth every penny of it.

I did a Tremec 3550 rebuild, and it wasn't that difficult. The video was an immense help, and I would recommend viewing it. At $20, it will give you an opportunity to look and decide for yourself if you think that it is something you want to try to do.

You will also need a magnetic base and dial indicator to measure the endplay ($20-$40). See http://www.mscdirect.com/PDF.process?pdf=1312&Keyword=Y

The tricky part is that you will need some shims to adjust the endplay in the two shafts: the new bearings will change the clearance. There is no way of telling what it will be until you get to the point that it is time to measure and check the clearances. Halon has the individual shims if you can wait for them. If you can't afford the wait, the auto parts store can sell you some shim stock and you can make your own, or have a machine shop make them for you. The shim stock comes in brass (easy to cut) and steel, in varying thicknesses.
