Powertrax TRANSMISSION - Manual (Page 2)

To install the 6-speed, a new cross-member must be fabricated. The transmission mount
has to be moved to the rear 3.75”, and since the motor and transmission angle down, the
mount will have to be .56” lower.
Some Muncie and T-10 transmissions have a 10 spline input and 27 spline output. Some
have a 26 spline input and 32 spline output. The 6-speed has a 32 spline output, so the
drive shaft yoke may need changed. Drive shaft yokes come with various hub lengths.
For this application, the hub should be approximately 3” long. When installed, 2” to 2-1/4”
of the hub should be in the transmission, which would leave 3/4” to 1” from the hub
shoulder to the tailhousing seal. If necessary , cut to the proper length. The hub O.D.
should be 1.885/1.886”. Drive shaft length is okay in most instances.
The 6-speed uses the same bell-housing, flywheel, pilot bearing, throw-out bearing and
pressure plate as the Muncie or T-10.
The 6-speed can be supplied with 10 or 26 spline input. If using a high torque motor or
going to change the clutch anyway, use the 26 spline clutch, because the 26 fine splines
are not cut as deep into the shaft as the 10 spline, which makes the 26 spline input 40
percent stronger.
Muncie or T-10 speedometer parts and rubber transmission mount may be reused or new
parts are available from Chevrolet.
The shifter will be 2” to 3” to the rear . If using a console, Long Machine manufactures a
special shifter handle to fit the console opening. Long manufactures the shifter that
comes with the 6-speed. Contact Long Machine @ 717 -202-8360.
