Judson runs this (or used to when their car was running 10s on a factory shortblock). The tranny is just like any other 4 speed from what I know about it. Uses a clutch to shift all gears just like any other manual.

1- Works with strait cut gears, and "dog" ring enguagement- no syncros

2-Gets driven with the clutch only on take off, regular 1-2/2-3/3-4 gear changes have no need for clutch use, just let off the gas, and change gears! Its a bad *** feeling, thats for sure

3- See #2

5- Its is expensive, Loud, Clanky, whines, and most of all, has to get rebuilt every so often, depending on the driver, to replace the dogs.

If the driver is soft on it, it wont need rebuilding. We have gone 2 years on dogs before.

Can you make 4th gear a overdrive ratio like they use at Pocono in the NASCAR races? Jimmy

I think You can get a 4th over drive. The cup cars make 3rd 1:1, so that they can run in that, then for gas mileage, they plunk it in 4th- usually only a few hundred rpms.

Jerico is the manufacturer out of Concord NC.

Dont quote me, but you *may* be able to get them with syncros.

If judsons car has a RR type in it, it has dogs. I can tell just by hearing the car being put in gear if it has dogs or not.
