Powertrax TRANSMISSION - Manual (Page 6)

Richmond 6-speed transmission number 7041626 will bolt to the Ford Top Loader bell-
housing. It uses the same flywheel, pilot bearing, throw-out bearing and pressure plate
as the small input top loader. It requires a Chevrolet 1 1/8-26 spline clutch disc. This input
was used for this application because the spline O.D. is larger than the small input top
loader and the 26 fine splines are not cut as deep into the shaft. This makes the trans-
mission input shaft 50 percent stronger.
The length of this transmission from bell-housing face to end of tail-housing is 24”, which
is the approximate same length as the top loader , so in most instances the drive shaft
length is okay. The long top loader will require a longer drive shaft. A GM 1 3/8-32 spline
drive shaft yoke will be needed, Richmond part number SY -1310 or SY-1330. These
yokes are also available from Chevrolet and Dana Spicer dealers.
The cross-member will have to be re-fabricated. The transmission mount has to be
moved to the rear approximately 4.75”. The motor and transmission angle down in
relation to the frame; so the mount has to be moved back on the angle of the motor to
keep the driveline angles the same and to keep the transmission from hitting the car floor
pan. The rubber mount used on this application is a Chevrolet mount used on the GM T-
10 and Muncie transmissions. A Chevrolet mount part number is 3913498.
The 6-speed is designed to use Chevrolet speedometer parts. The transmission comes
with an 8 tooth speedometer drive gear on the output shaft. Richmond has available a
speedometer adapter kit, part number 6360005-21. It comes with the parts that fit into the
speedometer hole, a short cable that screws on at the transmission end with an adapter
on the other to accept the Ford speedometer cable. The driven speedometer gear that
comes with this adapter kit has 21 teeth. If this is not the correct tooth count to make your
speedometer accurate, other gears are available from Chevrolet. There will be a formu-
la in the owner’s manual to help calculate the proper tooth count.
The shifter in most applications will be 1” to 2” to the rear of the top loader location. If
using a console, a special shifter handle is available from Long Machine that will extent
forward under the console and come up thru the original opening. The shifter that comes
with the transmission is manufactured by Long Machine (phone 707/867-1303). A cut of
1” to 2” from the backside of the shifter hole under the console may be necessary .
