Wondering if anyone has experience or info about either of these two transmissions.

The 5 speed can be shifted at higher RPM than the 6 speed with the OD gear, I'm talking about
normal synchros, not a faceplated deal, or other tooth engagement mods.

Torque capacity is evidently not the limiting factor with either because the gears are so big,
it is more the fact that the gears are really too massive for the size of the synchros (what I read anyway).

Everyone seems to like the T-56 of whatever version. It looks to me like the T-56 does have better synchros
than the Richmond, but the Richmond case and components are bigger and stronger.

Richmond says don't shift the 6-speed above 6500 but they don't say that about the 5-speed,
now the newer 5-speed OD, I have not read much about.
