Trying to learn here and get a feel for what I am looking at and looking for in the future. I bet I'm not alone.
4th gear is on top in this picture. I brake cleaned some of the teeth. It seems in the pictures when you look at the teeth that are straight up to the camera they look more pointed. But when you look at them in an angle from the camera they look more rounded.
How would you rate these THREE cleaned off dog teeth on top that are front and center?
The 4th gear has some light pitting on some gear teeth. Acceptable, not a big deal, or bad?

None of those teeth look good enough to reuse that gear IMO. They should have nice clean edges.. Get a new syncro ring and compare them. The gear mesh teeth should look like the new syncro teeth..
I am truckless..

This photo might still be too big but it shows the points you are looking for in a used trans.This is a HEMI box I did for a member on this board.

Thank you.
Not too small at all. Could be even bigger. It's tough to get a good macro focus in the pictures I took.
So....
What I was guessing was right. the point at the base of the clutching teeth is susposed to go all the way to the top. There is not another top cut to the teeth.
When I look at your picture I notice the 4 gear teeth are the most worn of all four. Still very nice and better that what I have, but am I analyzing that correct?
I your picture are any of those gears brand new? Obviously the brass syncros are all new since you got paid to rebuild it.
What's the advantage of the ball detent cover plate?

I went through a close ratio trans like that back in 2010. It was a 1973. My gears were a lot nicer than that and it would crunch doing a powershift into 3rd before I took it out of the car.
Gears are actually more expensive for that trans than the early wide ratio trans of the muscle era.
I got a couple decent used and new gears from "Paul" at Liberty Gears. A very nice guy to deal with.
You might be able to polish/deburr that shift fork and reuse it. There are some shops, I've heard, that will plate forks to tighen up clearances. Probably not cheap.
Converting to the earlier style forks/cover is probably a better idea, as mentioned.

the easiest way for me to figure out gear ratios, is to put it into gear, and start turning the input shaft. count how many times you have to turn the input, to get 1 full rotation of the output. mark them with a sharpie to help you determine.

Put it in a crate and ship it to Passon. It sounds like you are going to do some serious driving with that box. Better to fix it now than to sweep up the pieces later. R.
Ditto. I disassembled mine and degreased everything and took all of the internals to Jamie Passon. He hooked me up w/a rebuild kit and other parts needed and gave instruction tips on the rebuild/assembly. 3 years later, still works like a charm.

Looks like he cuts/files the clutching teeth down to get the point/triangle back again. But tough to see in the picture on his website of reconditioned gears.
Yes you can re-dress the clutching teeth back to original shape if they are not too bad...

If it were my tranny i'd get new forks
another vote for Jamie Passon - you could email him the pix and get some more feedback

Those are the stock steel forks, I would use them I did a older 2.66 box for a customer several years back, I sent his gears to Liberty to have them replace the engagemnet teeth ring,and they converted them to Pro Shift I called them back and ask why did they do that instead of replacing the rings with stock ones, thier explanation was that stock ones aren't availble. I had told them that this box was a street box, not a race box He siad put it together and drive it and then call them back, it would work fine It DID

Best way, procedure, and tools needed to do this?
Any pictures of someone doing this?
