You have a 4L60E trans with OD, no doubt.
On the Pontiacs, OD (overdrive) is when you have your shifter in "D". Firebirds have D...3...2...1
On the Chevys, OD is when the shifter is in "OD". Camaros have OD...D...2...1

I would suggest racing in "D" (Trans Am) (overdrive). There is a debate among trans builders as to which is better, but after hearing both sides I'm sticking with D/OD (overdrive).
You can research this further in the auto trans section if you like. There are quite a few threads on it.
