So for several summers the overdrive I “rebuilt” did not have reverse. It had it for awhile but then nothing. Checked linkage, did lots of reading, messed around, ended up driving it about 2000 miles with no reverse. Last summer the car sat and never moved. Mrs was getting pushy about this and I tried to sell the car this summer….stating there was a reverse issue. Of course there was no buyer. So 2 weeks ago I conceded and pulled the gearbox and overdrive out and found a transmission shop in the city that claimed to know about these. The shop called and asked more questions, they said right away they could reverse on the bench. Well I know I went through lots of linkage checks all with no result. They said a gear was smashed up really bad….I think I know when that happened. I confessed it also ran low on lube for a long highway run and so I agreed for them to tear into it. Today he called and said the overdrive drum is pretty worn. When I was in there several years back doing a “rebuild” I really had no idea what I was doing. So now I am waiting to see what this is going to cost me, but I will have peace of mind an expert will be rebuilding it and Mrs has settled down a bit thinking it is getting fixed.

You're aware overdrive, when engaged, locks out reverse? -assuming you have an R10 B&W.

many folks don't realize the OD has a separate oil fill plug for service and checking

I gave up, trans O/D issue
