The issues with my 88 B2 stem 100% from the previous owner's neglect and abuse and complete lack of any sort of mechanical knowledge hense the reason it had the wrong dispstick in the engine when I got it, I think from an F-series pickup as it measured to 8 quarts of oil yep when I drained the oil to change it the damn thing had well slightly over 8 quarts in it, no wonder all the seals and gaskets were blown and it was burning oil, but by the time I bought it the damage was done already. The transmission lost overdrive, shifts 1-3 were perfectly fine and reverse was fine, when it would shift to overdrive it acted as if you reached over and put it in neutral. A complete rebuild was done on the transmission and as of 3 years later in about 1 week it hasn't given me any issues, and about 9 months on the engine replacement and no issues there either.
Most of the problems I've found to have been caused by the driver with many vehicles.
