ok got an 89 gt 5speed... i broke reverse in the stock t5 pulled the tranny appart and literally teeth were missing off the gear on the lower shaft. now hears the question do i have this one rebuilt and hope it lasts or wait till tax time and say to hell with it and buy a new world class t5?
i've got three kids and a house... I don't have the luxory of just buying new ****...
if it was otherwise ok, and didn't grind or howl, just pull out the mainshaft, cluster shaft and replace the broken reverse idler and slap it all back together. Not sure why you'd want to do an entire rebuild on a t5 with just a broken reverse
Cost you less than $50 and you can spend the other money on beer and mods
astroperformance.com is the best place to locate a reverse idler...or hanlonmotorsports.com
A new t5 and a freshly rebuilt t5 are pretty much the same, no reason for a brand new one.
As far as what parts to rebuild, IMO, while it's apart do a small parts rebuild.
Might as well, you are going to have it out of the car, and that's half the battle.
Also, if you don't know what your doing, pay to have it rebuilt, not everyone is capable of it. If you remove the trans yourself, rebuild labor pricing won't be that bad.
