So my dads car has the manual 3 speed that was replaced long before he bought it and I did not know if it was the 2.77 or 3.03. Well I just pulled it and tore it down to see what the noise was in it. And looking at the internals/comparing to pictures its the 2.77.

My first question is if the tag on the trans is missing is there anything exterior that can identify between the 2.77 and 3.03?

Also anybody have any good links for parts for the 2.77?

I know many will say upgrade to the 3.03 but time is of an essence and I just want my dad to enjoy the car while he can. So I just want to figure out repair vs. simple used replacement/identification of a replacement.

Thank you..

Only the 64-66 6 cylinder had the 2.77.

They look very, very different. See below.

I'd be willing to bet Glazier/Nolan can supply anything you'd need for a 2.77.

Nothing wrong with the 2.77 as long as you don't beat the snot out of it. I towed a small boat all over the place with mine.

Tiny 2.77 with 4-bolt top cover:



By comparison, the 3.03 is massive. The 3.03 was the standard transmission with the 390 engine, as well as 289 and later 6 cylinder.

If you have a 2.77 I would say it would be silly to spend any money at all on it. There are so many good used 3 speeds out there that you can pick them up cheap. No body wants them. I have one I would sell for $50, it's a 3.03.

If you have the bellhousing and shifter he'd need, that's a pretty good deal.

Now, if the budget could stand some upgrading, a T5 5-speed can be bolted into that 66 with a few adapters, it would take the same amount of time as installing a 3.03.

Either way, you also need a C5ZZ-B slip yoke.

Not bad, but I didn't see anything Glazier/Nolan can't provide.

Glazier/Nolan?

Yeah, I mentioned them in my first post. They have over 9000 items in their catalog, and if something is not in that, they can usually find it.
