Re: Console
No.
The only difference between the D2 and the D1 console is there is a plastic blocking tab on the D2 plate to keep the shifter from moving to D1. Some people remove the plastic tab from the D2 console so they can access D1.

Re: Console
They had to do it to meet Federal noise regulations.
From the 4th Gen FAQ:
Same as the "Skip-Shift" feature that prevents the 6-speed manual trans from shifting from 1st to 2nd at low speeds.... the shifter is defected to 4th gear. They had to do that to meet EPA fuel consumption requirements, and avoid being classified as a "gas-guzzler".
From the 4th Gen FAQ:
Q: Why is there no selectable 1st gear for my automatic transmission?
A: On cars with automatic transmissions and the 2.73 rear (GU2) 1st gear can't be selected because in order to pass the Federal noise pollution tests, GM had to lock out selectable 1st gear. It has to do with downshifting into the lowest selectable gear at some speed as the car goes through the sound traps.
With the 3.23 rear end, the required speed is high enough that the transmission won't allow a manual downshift all the way to 1st gear. But with the 2.73 gears, the car will downshift all the way to 1st when manually selected thereby increasing engine and exhaust noise. So GM had to prevent 1st gear from being selected on the 2.73 cars in order to meet the guidelines.
However, making 1st gear selectable on these cars is relatively easy. Lift off shifter cover, locate plastic (nylon) stop at the right side of the notched selector ramp, use a hacksaw or X-acto blade to remove the offending (square) stop. Then you will have first gear.
