I beleive there is an aftermarket part that fixes the retainer problem on the 4500. I will tell you about another problem with them, though, incorrect lube use. Seems that they are very sensative to what goes in them. They call for a full synthetic 50 weight oil, Castrol is the factory fill, and the part number for it is on the right side PTO cover. Anything else will wipe out the syncros, especially regular gear oil.
BTW, there is no direct fit adapter to bolt the 4500 to a 235. That was the first trans I looked into when I got mine. AA doesn't have one for it. You might be able to favbricate something that would work, though.
