Transmissions
NEW!
The original performance
transmission, born in the Muscle
engines, the Richmond Super T10 and Super T10 Plus
The robust side-lever rail-shift mechanism and four- speed countershaft helical gears provide smooth, consis- tent shifts. The Super T10 Plus adds upgraded brass race synchro assemblies and a billet front bearing retainer
for the shifting smoothness and strength demanded by road racers. Both are available with multiple gear ratio options.

Super Street 5-Speed
with Overdrive
NEW!
The Super Street 5-speed
provides the ultimate blend
of performance and economy.
Low gear ratios in gears 1-4
ensure powerful acceleration,
while a high 5th gear ratio
yields a smooth and economi-
cal highway ride. Strong enough
it weighs in at only 106 lbs. (dry). A
durable side lever rail shift mechanism and a lightened 1st gear result in easy, consistent shifts.
