Inspection of a 904 torqueflite
Any bore is to be treated just like an engine cylinder bore; if it needs honed then it needs a bigger piston PLUS bigger rings. Not available. I throw the stuff away. You should by now have found a nearby source for transmission parts. If you start shipping hard parts....it's too easy to end up with clusterjunk. Part in hand for part in hand. And even after you've learned the proper terminology (and make sure the person you're dealing with has as well), and every stage of these builds are simplified, there will probably still be errors. And that's why people hate working on automatics. An engine you can throw together and it will probably at least run, but a transmission is unforgiving; one little mistake and you can feel it.
