Okay, here's my report. I drained the Hypoid 80/90 from both the gearbox and the O/D, and replaced it with straight Valvoline 50w racing oil, supplied by my transmission man. It took several seconds for the oil to work into the O/D channels, but then it kicked in nice and solid. No more slippage under acceleration. I haven't been on the freeway yet to really give it a good workover, but the switch to the lighter viscosity gearbox oil seems to have done the trick. At least, that's my preliminary assessment. I also notice smoother shifting in the gearbox. I wouldn't have thought I'd feel much difference there, but I do and I like the change.

II It's amazing the diversifications of opinions, btdt's, spec sheet conflicts, etc etc ...as an example, the D type O/D is the same on the MG as the early (read same model years) and the Triumphs. MG spec'ed straight non-d 30wt motor oil while Triumph spec'ed 80-90wt hyd. I use... 30 in my MG and Castrol 90 in my Triumph. both (all thee) O/D's run fine and have never given me a problem. Triumph did, in it's later days, suggest 30 was better. I've always used what was in the oem handbooks for that year. The real concern here is the additives in both (or lack there of) and how they effect the brass and copper parts and seals rubber used by the mfr.
