Default Questions for guys who rebuilt their own T56

Did you replace the bearings?

I know my synchros need refreshed and I will update the 3-4 fork, but what else is good to replace while Im in there? Car currently makes 362 rwhp. I plan to get a little closer to 400, but that will be it. I never go to the track, no racing, no sticky tires.

Thanks

I only replace bearings if it needs it. If your tranny is whinning it probably needs it, but always inspect it to be sure before you order them as you may not need them.

My tranny is off to the rebuilder right now. As a general rule they recommend replacing the bearings if the tranny has over 100K miles.

I didn't replace the bearings in mine since you need a press and all, plus they were all in pretty good shape upon inspection. Only things I replaced were the synchros, shift fork pads and steel 3/4 shift fork. If I would have had enough time, I would have opted for the brass shift pads so they wouldn't end up cracking on me. Best thing to do is tear your tranny down and inspect the internals. If anything is showing excess wear, then order the replacement parts. That way you're only out some down time and not extra cash.

The tranny is quiet, but it does have 80K miles on it. Right now its grinding when going into 3rd and 4th when cold.

What about the billet sliders? I saw those on T56 rebuilds site, but I haven't read much about them

The sliders are one thing I would invest in, along with the steel shift fork. I guess you could always error on the side of caution and invest in the bearings, but if you are rebuilding it yourself and have never done one it can be intimidating. Also the bronze pads are nice, I wish they were an more common option when I did mine.

I don't have a press, so if I decide to do bearings, I will just have someone else rebuild it.

Are the upgraded sliders necessary for 1-2, 3-4, and 5-6?

The sliders are just needed for 3/4 as they are the farthest away from the shifter and under the most stress.

Making sure I fully understand this....I don't need a press to do the synchro rebuild and updates that you mentioned? Right now I am planning on that, then if I disassemble and find some bigger problems, I can take it to a buddy with a press.

You'll need a press either way. People do it without one, I wouldn't even attempt it.

Right, you don't need a press. It would be easier to pull the 1/2 and 3/4 synchro housings if you had access to one, but it is not necessary. Only specialty tools you really need are a good set of snap ring pliers (flat and tipped), a quality torx-40 socket and an extra long 3 jaw puller.
