On the top of the transmission it has the markings GM2 and 591568
On the side is's got 8761930
I'm not the most mechanical person around but have a great mechanic. Any help on identifing the model would be most appreciated.
Life without beer is like a broken pencil.... completely pointless.

Any one else got a different book ? | | |
