Muncie 3-speed Tranny

Thomas · #1 03-17-2003, 06:58 PM

When I was searching for my first Muscle Car, about 7 years ago, I looked at a '69 L78 RS/SS that originally came with a 3 speed Heavy Duty Muncie according to the GM of Canada Documentation. It was owned by Mario from Early Birds in Toronto at that time. I may still have the sheet for it if anyone is interested.

I'am interested in that info if you still have it. Considering how unique the Heavy Duty Muncie 3-speed is, its worth a shot. I've seen it listed as RPO MC1 and RPO M13.

Feel free to PM or email me.

M13 was the HD 3-speed in 67/8.
MC1 in 69.

What's the casting # on the main case?

Thanks for your help on this Kurt S, and allow me to offer the following:

Two years ago, I spoke with a gentleman at the Turkey Day run in Daytona. He told me that he bought a new 69 L34 Camaro from a dealer in Northern FL. and it had a Muncie 3-speed. In 1974, he attempted to sell the car with no luck. All potential buyers claimed no 69 SS Camaros' came with a 3-speed. He replaced the trans with a 4-speed and eventually sold the car.

I have no reason to doubt the mans' word.

Should we rethink 3 vs. 4 speed Muncie transmissions?

That's what happened to a lot of the 3 speeds. Yanked and replaced with 4 speeds. Makes the manual 3 speeds pretty uncommon these days.
