Man that stinks! I really don't know much about transmissions, but from what I was able to find out, there is a part in the reverse drive that is prone to failure and is fairly easy to fix....the problem is that it's the last part you would remove when taking that trans apart, meaning that it requires complete disassembly to get to. So, if you're going to repair, you may as well rebuild since you're paying for the labor to R&R it.
My preference would have been to rebuild it, but I couldn't find a shop I felt I could trust in small town Western KY....the local shop recommended by a fellow forum member was a general repair shop and a Jasper dealer. I ended up going the Jasper route since they have a 3 year 100k warranty honored by any Jasper dealer in the the US, and there are thousands of them. My buddy who owns a 6-bay independent shop in NY has been dealing with Jasper for years and advised that their warranty support is good. I figured that being on the road with the RV at least I would have warranty access if I needed it.
FYI, if you go with Jasper, be advised that the fine print on the warranty requires you to change the filter and fluid at 5k miles. You can do yourself but save receipts.
You have the advantage of being home and not stuck on the road...if you have a good trans shop that you know will do the right job, you really shouldn't have to rely on a warranty...and it will likley be cheaper to have it rebuilt than go Jasper.
I would suspect that the fact it works in 4LO has something to do with the line pressure or whatever in the transmission rather than with the transfer case...if the transfer case was bad, it wouldn't go forward in 4HI either. I never tried 4LO when my I lost reverse, didn't think it would make a difference.
