I bought a used T56 out of an '01 Z28 with 80k miles. Shifted well according to the owner but I took it with a grain of salt. This tranny will be going into an '01 Silverado 5.3L extended cab which will be boosted soon, looking for 500+rwhp.

I finally got the T56 all apart and for the most part it looks okay. There was no excess metal on the magnets, all bearings look great and move smoothly, no chips in any gear teeth, no unusual gear wear.

The only damaged part I found were the fork pads on the 1/2 fork (I think, could be 3/4).
Broken tooth on the 3/4 blocker ring, which might have been my fault.
The synchro sleeve/out housing teeth for 1/2 and 3/4 look fairly worn too.
And the synchro teeth on 2nd gear are pretty worn, see pics. Worth replacing?

I was thinking of doing the stage 2 rebuild kit from The Gear Box, or maybe just the basic kit. After buying all the other parts needed for the swap I am low on cash, so I'm leaning towards the basic kit.

Thanks for the help.

Still kind of hard to make out the real condition of the dog teeth on those photos but it looks like many are in rough condition. That said if they appear to be blunted or the points are worn off, they are candidates to be replaced.

Recently when I rebuilt my T56, the dog teeth on all of the gears were perfect, not a bit of wear since I am not a big gear banger. However there was light wear of the dog teeth on the 1/2 syncro ring and that caused the issue of not wanting to easily shift into 1st gear when sitting still like at a light. Once this was replaced and the tranny was done, the problem was completely gone.

Since you are doing your own rebuild and saving bucks, dont be shy about replacing questionable parts especially since you like to bang gears as evidenced by looking at your fork pads. Wow. Its no fun to have to go back into it casue you skimped.

Also dont forget to check the fitment of the 5/6 driven cluster gear. If you had to pull it off with a puller, your good. If it easily slipped off the main shaft by hand, you just found another worn gear and possibly a worn main shaft.

This is not my transmission, I bought it used. The 2nd gear ain't cheap so I was hoping the synchro teeth on it would be okay to reuse.

Huhhh???

You will simply need to determine what needs to be replaced. No point rebuilding it if you dont install what it requires. From what your implying, 2nd is shot and needs to be replaced.

You said I like to bang gears as evidenced by looking at my fork pads. I was just saying that the previous owner did that, not me.

I'll go through the parts again and see what needs replacing. I can't afford to do the stage 2 build and replace gears. Thanks for the help.

First off, go ahead and replace your second gear. I know that it is expensive but if you dont all you are going to do is end up eating up the engagement teeth on the synchro associated with it. Second off a rebuild stage kit is the way to go, however if you are putting it in a truck (which is a lot heavier than a fbody) then there is going to be alot higher stress level on the tranny. With that being said I would look into a stage 3 viper spec. We have them for sale as a kit for you:

2nd gear is reusable with some minor deburring done to it.

Thanks for the input. I got a new 2nd gear and will probably go with a stage 2 rebuild kit but without the 3/4 syncho assembly, as it looks to be in decent shape, just to save some money.

I've reprofiled gears like that, but it's a toss up based on your pictures. I'm sure it might work if cleaned up some, but not ideal.
