6-SPEED AND SUPER STREET 5-SPEED WITH OVER DRIVE
TRANS AM, CAMARO, CHEVELLE, GTO, CUTLASS, WITH T-10/MUNCIE
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.
To install the 6-speed, the transmission mount must be moved to the rear 3.75”. This has been accomplished by several methods. Some cross-members have a removable center extension that can be removed and re-fabricated. Some extensions are welded in and have to be cut out and re-fabricated. Another method commonly used is to cut the center section out of the cross-member and weld end plates with bolt holes on each end, then fabricate a removable center section. This way the motor does not have to be pulled to install or remove the transmission. Some have also cut out the complete cross­member and made a frame to frame bolt-in crossmember . On some of the Corvettes, a pulley for the emergency brake cable needs to be relocated. When relocating the transmission mount, check the driveline angle in the car . If the mount is too high, the transmission will hit the car floor pan, and it will change the drive shaft angle, which could cause a vibration.
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 you may have to change the drive shaft yoke. For a Corvette, the yoke has to be open end. The hub on this yoke may be too long for the Richmond 6-speed. The hub length on this yoke should be cut to 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 tail-housing seal. In most instances, the drive shaft length is close enough to meet these dimensions.
The 6-speed uses the same bell-housing, flywheel, pilot bearing, throw-out bearing and pressure plate as the T-10 or Muncie. The 6-speed can be supplied with a 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 splines, which makes the 26 spline input 40 percent stronger .
T-10 or Muncie rubber transmission mount and speedometer parts may be reused or new parts are available from Chevrolet.
The shifter will be approximately 1” to the rear of the current location and may have to be cut 1” from the backside of the shifter hole under the console, but the shifter will fit the console with no modification to the console.

To install the 5-speed, a new cross-member must be fabricated. The transmission mount has to be moved to the rear 2.25”, and since the motor and transmission angle down, the mount will have to be .38” 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 5-speed has a 32 spline output, so change the drive shaft yoke may need changed. Drive shaft yokes come with various hub lengths. For this application, the hub should be approximately 4” long. When installed, 3” to 3-1/4” 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.
