    Odd ball transmission identification and fix

    Its also a 350! I'm pretty sure the 2wd is the same retainer but this one has a smaller bolt pattern then the sm465, i think its the same pattern as the car type but diameter is wrong

    It has 7 side cover bolts and it is fully synchronized. Just lost as what to do with the throwout bearing retainer. I can find the ones with the smaller diameter for cars and the SM465 all day but not this.

    How do i find out what my gear ratio is?

    I tried the tape on the wheels and drive shaft and it turned out to be a 3.73, Seems fine but is does rev pretty high on the highway because of the transmission only being 3 speeds. The fluid was actually replaced a little while back so i think i am good on that, But i get what you are saying.
