A4 shifter
Make sure the brake switch is working... you should hear a distinct clicking sound when you step on the brake.
A weak battery might not have enough juice to overcome a reluctant shifter solenoid.
Unfortunately, a simple problem (like the brake switch or battery) can interfere with shifting... someone then forces the shifter, causing damage.

This is definitely fixable. Might be a [damaged] reverse lock-out pin or a faulty shifter solenoid.
Or it might be something simple, like a brake-light fuse. That is, there might be something preventing a signal to the shifter solenoid. Do your brake lights work? See post #6: http://forums.corvetteforum.com/c6-c...-in-drive.html
Do NOT force the shifter... you might do more harm than good. And don't let a well-intentioned ham-fisted tow-truck driver force it, either.

If you're handy...
All fixed!!!!
The short version.........the lockout solenoid was overextended and jammed, not broken. I was about to order a new one from the local dealer ($249) and decided to try and figure out why it wasn't working before tossing it.
When you press the brake it extends a rod on a solenoid that moves a plastic piece out of the way of the release button on your shifter allowing you to put in gear. The rod on the solenoid was slightly bent and not aligned with the lockout piece. I popped it loose and bent it strait with a pair of needle nose and its as good as new.
The hard part was removing the ****. Now I can remove it in 10 seconds or less. The other obstacle was how to remove the linkage once the shifter was unbolted.....lift and twist clockwise.
If your shifter takes a dive don't pay a.dealer $800+ for replacement, It can be done start to finish in thirty min once you know how to get that **** off.
Thanks for everyone's help and feel free to contact me if you are replacing one yourself or just have questions.
