Internal pictures of/inside the back-half of my Duramax ZF-6, 6 speed transmission (just for reference, or if anyone is curious).
Shown here are the gears, from left to right: Reverse; 1st; and down below on the lower horizontal shaft is 6th. (not shown here, in the other half of the tranny, continueing in the same direction: 2nd, 3rd, 4th and 5th.)
