Help! Car does not move in drive or reverse

I was doing something stupid last night and tried to do a small power brake burn out. Well, aftrer letting off the throttle the car made some noise like the active handling system was trying to take control and now the car doesn't move in drive or reverse. The active haddling was turned off. I tried turning off and on , seems to operate ok. There are no current codes, the engine speed appears to drop down when putting into drive and reverse but no movement. No fluid leaks or nothing visual underneath. One odd thing is it will roll forward in neutral when pushed but won't roll backward??? It's like it is lock up in reverse? Tried disconnecting positive battery terminal for one minute, touched it to ground for one minute, re-connected, no effect. Any ideas??? Torque tube? Not sure where to start. Any ideas are welcome.
Thanks,
Clyde

Jack up the rear of the car and see if you can spin the drivers wheel seperate from the passengers wheel. If they dont move together,,,, thats most likely the issue.
heres a post for you that shows you the inside of the differential and how to fix the issue with hardened C6 ZO6 parts.

Theres another link in that e-mail with more info! Its some GOOOOD STUFF!



Thanks for your help! Do you think now would be a good time to put a set of better gear ratio in being the differential has to be taken apart and what would you recommend for a stock automatic daily driver? Do you think the cost would be? As always thank you for your advice.

Ive never replaced the gears or pinion carrier so, I can not comment on the process. I did just discoverer the special Kent Moore tool on E Bay for an AMAZING $29.00
Sooner or later I will find a junk rear I can fool with and learn the set up process.

I do not plan on doing the work myself. I have to have the work done. I'm going to try and find a reputable shop on Long Island to do the work. I am actually very pleased with the performance of my stock setup but I guess my question is if it is the differential output shaft that I damaged has to be replaced and while its apart should i go the extra mile to change the gear ratio since I'm getting the work done or just replace what's broken. What do you feel is the most cost effective thing do? I hear changing the gear ratio to like 3:53's is the way to go adds alot of performs power vs. stock gears I have of 2:73. What do you think the cost would be to have this done? Is the job of changing the output shaft much easier than changing the differential gears?

Today I went out to work on my problem and found my battery almost completely dead. There were no lights left on, no reason for the battery to go completely dead in a 24 hr period.
I jacked up the rear end of the car and spun the wheels as you suggested Bill and both wheels spin the same way together so your diagnosis would be the automatic transmission output shaft. There is something wierd teh car will not roll backward only forward. If the trans shaft was broke wouldn't the car roll both ways? Could I have a shorted selenoid of some sort maybe in the trans or something that would drain the battery and not allow the car to roll backward and not allow the trans to engauge in forward and reverse? I felt at the time I had my problem and heard the noise it sounded like the ABS, traction control was trying to kick in although it was turned off at the time.
Any other thoughts? Do you think the dead battery is just a coinsidence? Do you think I could have an electrical problem causing the trans to not engauge in drive or reverse and not allow the car to roll backward in netrual???
Transmission problem???

There are several things inside the trans that could have broken. Most likely a clutch drum/ Im not an automatic guy so otheres may have a better idea on the specific component. There are sprag clutches that only catch in ONE direction. Good luck on that one!Today I went out to work on my problem and found my battery almost completely dead.

There are people on this forum (sponsors) who do it and do it correctly. Pick one of them for a successful rebuild/repair.
Seen too many people on this forum use a local Mom and Pop tranny shop that was SUPPOSE to be great and able to build a bullet proof auto tranny that just plain sucked or they flat out lied about the work that they did. Once its sealed up, your buying a pig in a poke.
You live in Long Island. I highly recommend that you contact Chuck at Corvettes of Westchester. Its a hop skip and a jump from your location!
If nothing else, give him a call and discuss your issues, desired goals and performance needs. Chuck will give you an honest answer and if fixing your OEM trans is all you want, if it is possible, he will do it and NOT rip you off. He tuned my wifes 06 Coupe and WOW,,,he did a fantastic job. Ive see his shop and I was totally impressed!
