I don't know that anyone cares about this transmission--heck, I don't think I do anymore either--but in case it helps anyone here's what I found by poking around the web and asking some questions at http://www.ford-trucks.com...
The M5R2 transmission seems to have two main problems:
1) They leak from some badly-designed rear seals--that can be replaced with better ones--causing the transmision to become extremely distraught when the lubricant drains out
2) Most guys who use them say they just don't shift very well, and that it's a very unsatisfying transmission for those of us who enjoy rowing through the gears
So, no M5R2 for me. That leaves me with a choice between a T5 modified for a forward-mounted shifter, or a Tremec 3550 set up for the same.
