Rob,
If you drive the trans from the output shaft (driveshaft end), you MUST run the
drill
counterclockwise. Damage to the OD will occur if you try to engage it running
the
other way. If you are driving it from the input shaft (bellhousing end), then
you must
run the drill clockwise. You can drive either end properly provided you go
only in the
right direction. Note that if you use the drill technique, you'll need a pretty
powerful 1/2" drill minimum or you won't get enough speed to build pressure in
the OD
hydraulic circuit. About 1500 RPM under load should do just fine. 1200 might
be
enough - I say 'might' - I wouldn't say you have a problem if it won't work at
that
speed - switch to a bigger drill before you suspect a problem in the OD.
