Re: how do i know what transmission i have?
It is most likely a Muncie SM420.
Here’s a link that's full of information regarding this transmission: http://www.novak-adapt.com/knowledge/sm420.htm |

Re: how do i know what transmission i have?
I agree with what Markeb01 said, only real way to know is to find the casting numbers and run them

Yes more than likely it is the muncie sm420, assuming your truck is a 2x4, if it is a 4x4 its more than likely the sm465...bascilly the 4x4 version of sm420

Re: how do i know what transmission i have?
The SM465 didn't come out until the '68 model year. All light and medium duty GM truck 4 speeds prior to that were the SM420 in both the 2wd and 4wd.
