You're not going to need overdrive until well past 150mph...
I'm more concerned with the spread on the way there. The old MT82/Tremec will have 30mph, 30mph, 40mph between three gears, while the new MT82D4 has a whole 40 and 50 mph between just two gears...
70-170 in the Tremec and 80-170 in...

This must have gotten started by some idiot who sprayed half the bottle of oil from the cleaning kit on the filters when servicing them.
