Transmission code on spid?

Looked at a 70 cst 1/2 ton 2wd with a trans code of "M38 3 spd auto trans" I know most of the autos were m49. Was this a 350 or 400? It was gone so i couldn't look. Just curious.

Re: Transmission code on spid?

that is the car way of saying TH350. A hand full of trucks ended up with that. You are right in thinking it should say M49.

The M49 code was used for the 350 and 400. Sometimes you will see an asterisk behind the description on the 400 but not always.
