It is my truck that I have had for 8 mos now. Yes, I drive it. It has a reverse in the far left, upward (toward dash) position. It has a 1st (actual GRANNY), 2nd, 3rd and 4th forward gears. 1st (up), 2nd (down), 3rd (up), 4th (down).
As I have stated before it is a 3 speed case (gm casting number 591195) and is stamped with a 3 speed serial number.
