Picked up this gsr trans a while ago and one of the bearings took a crap in it i guess, I have never used this trans and was wondering if I should go ahead with rebuilding it, I was planning on getting new syncros,bearings,lsd the whole works. Im not sure if the gears are worn down/damaged to much what do you guys think? This will be my first trans rebuild so im a noob.

Rebuildable, yes.

Will it be cheap? NO!

3-4 combo, 5-R combo, ISB and seals, 1-2 slider, lots of deep cleaning.

I'd guess easy $500-600 in parts.

Can you feel the marks on the gear teeth of gears 2-5 at all? Or are they still pretty well polished and smooth?

I would give everything a good solid cleaning. It makes it 10x easier to check for wear. When parts are dirty it tends to give a false reading. From what I can see its going to run some $ to get it back in shape. I would also not run that 1st gear in addition to what bone suggested. Check the rest of the forks to see how they clean up. They should measure between 7.4-7.6 mm. If under those parameters...replace them.

Thanks for the replies guys I appreciate it, Im going to head out and clean the parts up good and look them over again and ill get back with my findings.

They are pretty smooth, would rubbing/sanding them with something like a scotch brite polish them up a bit more or would that not be good? overall though I think they feel pretty good

You can wire wheel them. Just make sure your wire wheel is not to aggressive.

I prefer 120 grit flapper wheel in an air grinder to debur the sliders and hubs. It's not very agressive so you really have to try to mess something up!

KISS factor

Ok I might try and polish them up a little then, I sprayed the gears down yesterday until I ran out of brake clean and carb cleaner but they did clean up a bit, I have yet to completely disassemble the main shaft waiting on some tools to arrive first but after cleaning these so far look the worst to me. I also measured the shift forks and they are within spec.

Reverse

1st/2nd slider

1st looked pretty rounded

5th/rev slider? this one looks quite nasty has a bunch of small metal pieces ground into it

Sorry about the crappy pics they are kind of hard to see, I will tear down the rest of the mainshaft and post my findings.

The 2nd gear teeth on the 1/2/R sleeve don't look too terrible but it's hard to see. They seem to still have a fairly decent point to them. Can't see 1st. Reverse is pretty beat up on it, so you may want to just replace anyhow.

3/4 hub is scored. Can't see 3/4 sleeve teeth to make judgment.

5/R sleeve should be replaced due to 5th gear wear.

Ill see if I can get some better pics up tomorrow the wifes pink camera doesn't like greasy parts lol.

Got some tools today so I pulled apart the mainshaft not looking so good




And this bearing feels like it welded itself to the shaft I put quite a bit of pressure on it and it didn't budge at all, sprayed it with pb blast and ill let it sit overnight.


Overall its looking pretty crappy I think, but I do have good news I should be picking up 2 GSR gearsets tomorrow and hopefully I can make one good one out of them all.

Ouch! That looks like someone starved it for oil. Those needle bearings don't normally go bad.

Mista Bone

recycle bin is my suggestion.

MR.johnson

i just tossed one that looked like this.

Thats what I was thinking too

That thing has had quite a bit of heat through it. Looks like somebody thought MTF was just a suggestion. That C-shaft looks unusable. Hopefully the two extras you are picking up have some usable parts in them. I would pretty much bet on the fact that you are going to be buying a 3/4 slider set, as rarely is it that I find one not abused thoroughly. We seem to not understand how clutches work when we beat the **** out of these transmissions.

Picked up the box of FREEBIES!!!! today, was told they were parts from 2 gsr tranny's

Layed out most of the stuff, counted the teeth looks like 1 is a gsr and 1 is an ls no big deal

This mainshaft looks quite a bit better, I have to clean everything up still but I think I should be able to piece a good trans together.

That LS 3/4 is shot, but that one you have labeled as GSR has some promise.

Whats a clutch?? lol

i also use the same technique and it works wonders.
