Take a look at the link below for some info on the T-85 3-speed and the T-10 4-speed both from Borg Warner. The T-85 was very beefy and heavy. It did not have a syncronized first gear. The T-10 was developed from the T-85, but it was not as rugged. It did well for chevys, fords and the like, but big block Mopar power required a lot more strength. The original T-10 had an aluminum case, but the later "Super T-10 had a much stronger steel case. GM used the Muncie as a replacement for the early T-10. My '64 GTO had a Muncie 4-speed that worked quite well for me, but the biggest engine that I put in front of it was a '65 421 out of a Pontiac 2+2. Max Wedges and Hemi were just way too tough for any of those. I had a couple of cars with the T-85 overdrive and loved that trans except for having to do the old double clutch to down shift into first as I rolled through a corner.
