Perhaps your brake interlock isn't working. That's the deveice that releases the shifter when you depress the brake. Most cars have a manual override. You probably will remove a cover and press a button with a pen or screwdriver. It should be near the shifter. Check your owner's manual for details.
The transmission on this car is tiptronic, which means you can drive in automatic or clutch-less manual modes. The 'M' stands for manual, and when you put the car in this gear you can shift up ('+') or down ('-') while you drive.
If you plan on using the original shifter then you will need the one specifically for your car. If you plan on installing a universal shifter, then it will come with a new cable.
It needs to be in park or neutral to start. All cars have a "safety" switch which prevents starting in gear.
If it's stuck open, yes you can. If it's stuck close, no you cannot drive the car.
depending on car, u will need new computer, torque converter, transmission, auto shifter, bell housing (if not included with transmission). The last answer was backwards giving you info for changing an automatic into a standard.
There should be a shift release slot in the upper left corner of the shifter. If you stick a pencil in the slot you should be able to release the car from park. I had to do this for about two weeks and then it fixed itself. so it may only be a temporary solution but it should help you drive when you need to.
If by some chance you are asking " why is my shifter stuck in park and you cannot shift out of park " then just turn the key to the first notch, no ign. lights, then put the shifter in neutral, start the car and drive to your local garage. They can fix it for you.
Sounds like its starting off in second not in drive
The button does not switch from Overdrive to Automatic. The button just turns the overdrive off. Overdrive is not a separate drive system as your question implies. Normally you leave the car in overdrive mode. That way the transmission shifts into overdrive at highway speeds, thus saving fuel. If you are saying the transmission is stuck in overdrive and it will not disengage then seek out a A/T professional.
The gears are always being used in an automatic car, if you are asking about the 1 and the 2 on the shifter, i dont know what those are for, you can use them to slow down if your brakes go out.
Provided you could start the car, there is no reason whty you couldn't as they function almost as an automatic does.
More than likely - no.
