69 L78 Tranny question

[Chevy454]

Just an uninformed guess here, but I would have thought the M-20 would have been the base manual tranny behind the L-78 for the Camaro/Chevelle/Nova...

According to the Chevrolet SS Muscle Car Red Book:

1969 CHEVELLE SS - L78, if you ordered an auto it was the Turbo Hydra-matic (3 sp.)...if you ordered with the manual it was a 4 sp. of several choices but the M22 was only available with the L78 or L89. The 3 sp. manual was only available on the 325 and 350 HP versions. The 3 sp. auto, Turbo-Hydra-matic, was available on all versions.

1969 CAMARO SS - Says the Turo Hydra-matic 3 sp. was available with all SS engines. Goes on to say the only manual transmission available with the the 375 HP versions was the M22. Other 4 sp. versions available on other HP versions outside of the L78 and L89. The 3 sp. manual was only available on the 350/300's.

Quiz tommorrow!

Interesting Dick, thanks.

Seems every source has a different story . We need Jerry to do one of his books on Chevelles .

Ah the heck with it, I'm taking up drugs

Don, taking a look at another resource on your question....Mike Mueller's Chevelle 1964-1972 book says regarding the '69 Chevelle SS..."Turbo Hydra-matics were also offered behind the brutish L78 for the first time, as were all the manuals, including the Super Sport special MC1 3 speed and M20 wide ratio four speed units that previously had been spared the wrath of 375 horses".

This would support what the other fellas said about the MC1 which the Red Book did not mention.

Thanks Dick, I knew I read it somewhere. Before I posted the question I quickly scrolled through that book, but it didn't specifically jump at me. I see it now, page 73

What I would really like to see is a copy of the "Dealer Option Order Book" where it would indicate what "other" options needed to be ordered with specific options. For example, when ordering the Z25 SS Option, it was necessary to order J52 Power Disc Brakes. Was there a spcific "tranny option" required when ordering the L78? I still think not, but am always learning
