I have only seen the shockproof as it was drained out of a trans and it
seems to be "sticky" compared to the rest of the oils...Stringy and
definitely approaching the 140 wt oils. No feedback from guys who have used
it as it seems most of them are off roaders or racers who beat them hard and
are not really street machines.
The MT90 is a good all around stock hp oil that shifts nice when cold and
will smooth out some notchy synchro's at times.
High HP engines can wear the ring/pinion prematurely, so an oil like Swepco
201 is appropriate. The Porsche racers use it with great results.
I personally ( and no expert on the chemical properties) feel that most name
brand synthetic oils are pretty similar these days as the additive packages
have improved so much over 10 yrs ago or more. GL5 is fine these days and
its not so important to use only a GL4. Most of the trannies I take apart
have been used with GL5 and not any significant brass synchro wear is
evident.
The big key is to change it every 2 yrs or so.
