Can't help you with #2, but for #1 the answer is "it depends." The angle of
the pinion should be the same as the angle of the engine/transmission --
parallel but not in direct line. In other words, if your engine/tranny tilt
down by 3* your pinion should tilt up 3*. The attached picture should
explain. It doesn't say, but I believe the ideal pinion angle is in the 3-5
degree range. 0 doesn't let the u-joints work. If the angles aren't the same
you'll get vibration vs. whine though.

Subject: [Mgb-v8] Two Questions
I Have a couple of questions that I hope someone out there may have the
answer to.
1. What is the correct pinion angle for an MGB with a Ford 8 inch axle? I
have installed one in my B and have a significant amount of humming noise
coming from the axle. My suspicion is that it needs a rebuild but I wanted
to check the pinion angle first before I pull the third member.
2. Does anyone know what type of automatic transmission fluid goes in a T35
transmission? Its the transmission that was coupled to my Rover V8 when I
installed it in my B. I have been using type F but that is just a guess.
Thanks for your help.
