How much to rebuild a T5

Do it yourself it is easy, just set aside some time. The worst part is getting the tranny out to do it.

after going through two t-5's, i'd recommend just going with a tremmec if you can afford it. with anything more than stock power the t-5 isn't going to last. if you choose to get it rebuilt though, i believe it cost me around $300 for everything

See http://www.ttcautomotive.com/English/onlineorder/product.asp to download a FREE service manual for T5 or Tremec 3550
You will need the Adobe Acrobat viewer which is also a free download – http://www.adobe.com/products/acrobat/readstep2.html

See http://www.hanlonmotorsports.com/ or http://www.ddperformance.com for parts

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

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

Thanks Jrichker , Great info there , just picked up one of the tapes on the T-5 rebuild . Hope to tackle that myself here soon!
