Newbie with trans problem

You will never know which one is the best choice for a rebuild until you take them apart.

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/index2.htm for parts

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.
