Manual Tranny Numbers

[prossett]

These are the numbers stamped onto the tranny passenger's side of my 1983 Jimmy, converted to manual gears L-1-2-3 some time before I bought it:

No. 5
GM
465452

Does anyone know what these mean?

I have 3rd gear that keeps popping out, so I will soon have to take it out and open it up.

when you say 3rd.. that is the last gear? mine pops out of second which is up... if I get off the gas it just slides right out.. I was told the syncros... maybe you got the same problem

Yeah, RootBreaker, it's the same gear, the one up to the right... What's extra bad for me is that I'm in the Middle East with it!
