I love my MTX-75. It's had the crap beat out of it. Wheel hop so bad it should have broke 10 trannies, power shifting, miss shifting, and other fatal handling along the way.
It's taken it like a trooper and never complained once (except for a broken shifter cable - I blame my heavy hand and the B&M's revised geometry for that)
I drained the fluid at 1000 miles and have been running the Mobil 1 "cocktail" ever since. I change it once a year (nearly 3 years & 27k to date)
I am also now going to find the largest piece of wood I can find and knock on it profusely, but I just thought I should give props to at least the revised MTX-75 anyway...
