Boy the 727 is about the easiest tranny to build if he can't do that he needs to retire. All the crap you see in the converter could have been from the tranny.

If it is a big name converter I would have it rebuilt and sell it. Ask them if anything failed as the tranny guy could just be feeding you another line of crap. Then get a slightly smaller converter if your cam can handle it.

If he knew that he was the one who screwed up he should be able to rebuild the tranny correctly as there are not many trannies simpler than the 727

Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.
