Hello, I have a 440 engine, (engine block code: 4006630-440-3) I was just wondering how can I find out which transmissions will fit with my engine, and if you know any that will work?

They are going to go in my 1967 Plymouth Barracuda.

I have easy access to the engine, so if you need anymore information/pictures on the engine I will be happy to give you the information you need!

There were two (maybe three) factory transmissions. The 727 automatic as mentioned above and the A833 4 speed manual. I don't know - maybe the three speed manual was found behind the 440 as well. Anything else requires some custom work.

Yeah, the big block 727 and the A833 4 spd, the 3 spd was behind the 413 back in the early 60s, don't think it was ever offered behind the 440, but it could be one of those really rare options.

OK, then the 727 big block bolt pattern (that's 383/400/413/426 and 440, also known a B or RB blocks) or the big block manual bell housing (etc.) to bolt up.

Transmissions that will bolt up, doesn't need to be correct.
Then you can also include the NP435, which is a truck transmission, but might be a good option if you have a shorter rear gear, such as 3.23s or the even taller 2.76s. (There are two variants, one with [NP485L] and one without [NP485A] a granny gear.) The Novak Guide to the New Process 435 Transmission

Numerous other manuals, such as the NV4500 and T56, will bolt up with simple bellhousing swaps. New automatics, such as the A518/46RH/46RE can also be used with an adapter (MENU Home Catalog Contact Info -or- JWCatalog), but also require modification to the tunnel for clearance and may require a computer or other electrical control device to function as intended.
