Manual (Standard) Models and Types
Although from my experiences all manual equipped V8 Monzas had Saginaw 4-speeds, I once read that Muncie made some so-called Saginaw style transmissions that were used in the V8 Monza. If anyone knows anything about this e-mail me.

Factory Bellhousing V8 Monza, GM p/n 354496 and Nova GM p/n 360162.
(pictures copyright Bob Gumm's "Building the V8 H-Body" website)
Here you can see the factory V8 manual transmission bellhousing (GM p/n 354496). I've also discovered a second part number (GM p/n 360162) that looks similar to p/n 354496 except it has the bolt hole that is missing from p/n 354496. Notice how driver's side of the bellhousing has one bolt hole missing! This was done for clearance purposes. Also, notice the clutch pivot ball hole is positioned at the upper right of the bellhousing. This again was done for clearance and because the clutch arm is cable operated. I suggest you use a scattershield bellhousing for performance applications. You will have to dent the firewall to trans tunnel area slightly to use a scattershield bellhousing.
5-Speed Manual
Some H-Bodies had Borg-Warner T-50 5-speeds. If anyone has anything they would like to say about this transmission please e-mail me.
Clutches
Clutch Cable Part Numbers
GM Group 0.854.
There were five different clutch cables made and their specific application varied with the engine in use. Since many clutch cables are being sold online it's critical that you get the right one. Before you buy a cable use the list I have compiled below to ensure you get the right part number for your application. I don't sell these parts, I just list them for your information.
- V8 (262, 305, 350 cu.in.) GM p/n 465472
- V6 (196 & 231 cu.in.) GM p/n 465472
- L4 (Cosworth 122 cu.in.) GM p/n 364673
- L4 (140 cu.in.) GM p/n 364672
- L4 (155 cu.in.) GM p/n 463006
Clutch Cable and Adjustment
Adjustment is made with the return spring removed.
- Place cable through hole in clutch fork.
- Pull cable until clutch pedal is firmly against the rubber bumper.
- Push clutch fork forward until the throw-out bearing contacts the clutch spring fingers.
- Screw pin on cable until it bottoms out on clutch fork surface.
- Turn 1/4 turn tighter and position pin into groove in the clutch fork.
- Attach the return spring.
- Use the above procedure to produce .90" (plus or minus 1/4") lash at the clutch pedal.
- Cycle the clutch 3 times by depressing and releasing the pedal and recheck.
ShiftersThe picture on the left shows a Mr Gasket V-Gate Shifter installed on a Muncie 4-Speed transmission. This is the shifter of choice for many die-hard drag racers. Installing a Mr Gasket V-Gate Shifter (P/N 411 8156) will require modification to the reverse linkage as well as a huge hole in the transmission tunnel that will need to be reinforced. The reverse shift rod will need to be moved to the opposite side (driver's side) of the Reverse Shift Handle to clear the Torque Arm Bushing. Even then I had to shorten the Torque Arm to move the bushing back several inches and fab a mount that I had welded to the transmission crossmember. The reverse shift rod also had to be custom bent to navigate it's way back to the proper position in the reverse shift arm. Some of those who have shorted the torque arm have reported that it eliminated wheel hop. I never had wheel hop as I have always had a Competition Engineering traction device installed. I'll have to take a picture of the CE traction device which consists of boxed lower control arms inside an adjustable cages that bolt to the rear axle housing.
