Yet another 904 rebuild thread, what kit?

You seem to know everything. No sense in giving you any suggestions.
Sorry I even tried. Lesson definitely learned.
Good luck with your trans.

Sorry you feel that way. I definitely DON'T know everything, otherwise I wouldn't have bothered to start this thread. I'd have just rebuilt my transmission and enjoyed my car and not dealt with all of this drama. But I'm also not some novice that's incapable of evaluating the information I'm getting. Yes, I had an idea of what I was going to do before I started this thread. What's good for a 500 hp street/strip car is not the same as what's good for a 300hp daily driver. If you'd given reasons why I should follow the same build plan as guys that are making an extra couple hundred horsepower or more, I would have been all ears, just like I'm listening to transman. But just saying "red plates are better because they're more expensive" doesn't cut it, because I do know better than that.

Get a spring and roller kit and replace the old ones in the sprag. Take a photo of the way the springs and rollers are mounted. There is only one RIGHT way to put them in, but you sure as hell can get them in wrong. You might want to make sure the pump bushing is Perfect, if not replace it. You can see how good your pump bushing is/or is not by looking at the hub(neck) of your converter. Check all bushings. By the way, if the pump bushing needs to be replaced, get the babbit one, not the bronze one. Consider getting a complete washer kit, not expensive and might be required. There is a small thimble filter called the governor screen, again cheap, and why not change it while the transmission is apart. Sonnax makes an intermediate accumulator repair kit you might want to also think about, and both Sonnax and Superior have an upgraded reverse servo piston for you. On the rear clutch there is a diaphragm spring that is known to crack, again, an inexpensive item. At the rear of the trans there is an output shaft ball bearing. Check it out too. By all means get the ATRA book on repairing the transmission. It will be full of information on clearances etc. All your parts would be available at a local Transtar parts warehouse. Google them to get the one nearest you. Hope this all helps.
Have fun and "DO IT RIGHT ONCE"

Awesome. Again, thank you sir for taking the time to lay all that out. This is the kind of info that I was looking for. I'll tear my transmission down first and check the tolerances/clearances before I order my parts, so hopefully I can just order everything at once, get the right parts and reassemble in one go.

Here's a picture of the hub on the original converter. Sorry for the dirt it's been under my bench for a few years, just like the transmission. It does have a crack, which I'm told is pretty common on the earlier 904's, but the hub is smooth. Probably should just replace the pump bushing anyway. Obviously I'm replacing the convertor.

This is the manual you're talking about right?

I've already got the 727 book by Carl Munroe, but the ATSG book looks like a good one to have too. This is the one I've already got
