Sm420?

[redrustbucket]

Talked to a guy today about a spare tranny he has laying around for a 57? chevy p/u. All he knows is that it's a four speed with a granny low. Sounds like it could be right but I won't know till I get a look at it. Where do I check #s to see if it's what I'm looking for?
Thanks, Jeremy

465 wasnt made that early so its a 420.

Novak Adapters (mostly Jeep stuff) Has pictures and info on most old trannies. Makes it real easy to ID.

Psst. Go here and look under transmissions.

Or just click the "Technical Links" link at the top of this page

If it is a chevy 4 spd w/ granny that early, then it is a 420. 465 started in 69

IIRC its 67, as 67 is the last year for the SM420.

Damn you lucky bastard I've been lookin for a 420 for a year, followed leads, even bought a tranny thinking it was a 420 (was a 465), can't ever find anything local for a decent price.

If you are going to register this truck you're going to need to install a reverse switch. (I think 67 was the only year to have them)

I have one in my truck and I love it.

yup , got em all over the place . Not new if thats what you wanted. PM me if you wanna talk bout gettin one. Have both the old school no seal on the front input and the newer style. Cal west trans out here can also do up a core and the tranny builder there is a good ole boy from the mid west named Kelly and he knows how to build em and has cores .
