i have what i believe is a 57 chevy three speed manual trans. i would like to sell it, but first i want to make sure it is what i think it is. the casting numbers on the side are as follows- main case: gm 13 3845122 d 187, tailshaft: gm 28 0237 8707196, sidecover: 3845044gm. any help would be greatly appreciated.
thanks in advance

I have a 37 chevy truck with a built 305 bored .060 with a mild cam,sanderson headers,performer intake manifold and a 600 cf carb. I would like to go with a dual quad set up either using 500 edelbrock carbs or hollys 390. Which one would work for me

Well what's you thinks it is?

WHAT?

Sorry, What I ment is, What Transmission do you think it is in the car?

to be honest i have no idea. it was my father's, and he said he thought it was out of a 55-7 chevy. it only has two shift levers on it so i assume it's a three speed. it also has no mount on the tailshaft. this is all i have to go on.

I looked for u but I did not find the castings. All i can suggest is to google Chevy transmission numbers or sombody here will pick up where I left off or send you to a site where you could decode those numbers. Sorry I could not do more for you.

thanks for trying!
