I'm looking for some pics of what would be acceptable wear on the clutch/synchro teeth of a gear. I took my Corvettes T56 apart expecting to only upgrade your typical items but finding want looks to be excessive wear on all the clutch teeth except 1st gear.

The service manual shows some basic drawings but actual pictures would be a huge help. If anyone has some please post, it would be very helpful.

Thanks

You might try a different approach and post some pictures of what you are seeing so others may comment on the amount of wear you're observing.

Take some pictures of the damaged teeth and contact Rick Kim

A good rule of thumb is when in doubt, replace it. A witness mark (mark on the gears but no loss of sharpness on the tooth) is acceptable but any wear should be replaced.

These were replaced:

Thanks for the pics.

It's difficult for me to get a clear picture that shows the condition:

I ended up having them inspected and was told my 2nd, 5th and reverse gears need to be replaced. Which I agree.

I'm looking at around $2500 for the gears and input shaft, 9310 G-Force main shaft, bearings and rebuild kit (Synchro assembly's, blocker rings, billet keys, bronze pads, etc). What are my options, if any, for around this price? I'm not looking to buy a used trans right now.

Also, what would be the best way to sharpen the teeth? And has anyone tried this? They should be case hardened steel, I'm assuming .030 deep and 60Rc.

Thanks

Hello Rick,

I have been looking at Tick performance, Zip Corvette and thegearbox.org for parts. It looks like you offer all the items I would need as well.

I can give you a call and we can go over what I'm looking to do. This is going to be a weekend car with maybe a couple visits to the track. I'm looking to rebuild this transmission then doing a 3.90 or 4.10 gear swap.

Engine will most likely be a 383 stroker LS1 at 12:1 compression and possibly a bit of nitrous.

I was not planning on running into the transmission issues (gears, main shaft and input shaft) so I'm trying not to spend a lot on getting this back together. Below is a pic of the main shaft.



Thanks,

Josh
