Rebuilding a T56

I have a T56 that I got cheap because 2nd and 5th synchros are going out.

I've never built a manual tranny before... you think its something I can tackle, or are there too many special tools and techniques to get it right?

I hate you. But yes, there are a few special tools that facilitate disassembly and assembly. I'm not saying it can't be done, but....

Not that I've done a T56, but you've rebuilt automatics right? Can't be worse than that.

JMO, autotragics are WAY easier to rebuild then manuals.

I just did one this winter. Had never rebuilt a manual before either. I found one cheap with second gear out. The syncro engagement teeth on the gear itself had stripped. Common problem from what I have read.

I have the factory rebuild manual (PDF file) that includes exploded parts diagrams, disassembly and reassembly steps/instructions, and parts inspection procedures with accept/reject criteria for replacement. Be happy to email it to you, but I had no problem finding it on the internet for download.

Here is a link showing a tear-down and rebuild with pictures.

T56 Rebuild

Between pictures like these, other forum threads I had found, and the rebuild manual, I had no real problems. When disassembling, I took all the parts and stacked them in order on a wooden dowel as I removed them. I made a stand with a 2x6 wood base and affixed wooden dowels vertically for each sub-assembly. This made reassembly a breeze. I would upgrade to billet syncro keys and a metal 3-4 shift fork while in there.

I purchased my rebuild kit and parts from Tick Performance and Gear Box Transmissions. They both have websites and were great to deal with.

Other than the long jaw pullers, which I made by modifying a standard set, I had everything I needed, shop press, dial gauge and base, snap ring pliers, etc. Just took my time and studied the diagrams in the manual and pictures before and during reassembly. Once you are in the case, it makes more sense as to how everything works and goes together. It was a great learning experience and thus far it is running and shifts great.

Excellent link... THANKS!

I have everything I need except the long jaw pullers and the press, but I know a guy with a small press I can borrow, and maybe I can modify my pullers like you did.
