Mark, I'm sure this comes too late. I've been out of town and am
way behind on the q-list mail.

Use the High Performance Gear Oil  75W90 GL-5 in the rear. Period.
Do NOT use this in the transaxle. Way bad for synchronizers.

You may use MTL or MT-90 in the front.  The MT-90 is closer to
the factory speced 75W90 GL-4 weight and will give better heavy
duty service in terms of bearing and gear life.  It handles more
pressure and is slipperier than the MTL. I'm running MT-90 now.

OTOH, MTL makes for better synchro action and cleaner shifting, at
least when cold.  The BMW crowd loves it but they don't have to
worry about final drive gear loads in the front box.  I used MTL in my
first transaxle. The modified engine may have increased the loading but
I was beginning to develop bearing whine shortly before I swapped it
out. Shifting was great though. MTL is probably OK on stock car with
minimal hot shoe application.
