light green most likely, the easiest way to find out is pop out one of your taillights quick and have somebody sit in the vehicle with the key on and put it in reverse then probe the wires coming off your reverse bulb socket with a test lamp until you find power, this way you know which wire for sure. Thanks for using fixya!!

Check the linkage that goes from the shift lever down to the transmission. It sounds like somewhere along the line, it has become disconnected or has broken.
if that parts are clean then It sounds like you have a shift control solenoid that has high resistance causing the hard shift you describe. Scan the PCM for trouble codes if none are present you could have a internal transmission problem.

Yea, hummers are notoriously unreliable. They are gas gusslers too.
I'm assuming this is an automatic?
When the transmissions computer detects any malfunctions, it will give you a check engine light, or something along those lines.
Do the normal checks such as checking the transmission fluid level as per the user manual.
For further diagnostics you'll need to take it to a mechanic. It's impossible to diagnose a problem like this without driving the car and being able to reproduce the problem.

Like the first guy said. The small roof lights that run along the front edge of the roof leak water, usually during car washes or very heavy rain.the corners were my culprit. Clear silicone was the answer.
(Dont get it anywhere you dont want. use sparingly as it can be a pain to get completely off a nice paintjob)

Dead Battery? Bad starter motor?
Try pushing on the brake and making sure its all the way in park.
Turn the steering wheel back an forth a little to remove the key.
None of those work, Call triple A, find a shop.
