Interesting M6 Transmission Problem - 05 GTO
This is my first post so hello from central TX. I did a little searching to see if anyone had similar issues, but couldn't find anything so I thought I would post to see if anyone had any insight into this problem.
Over the weekend, I was out driving my goat pretty hard at high speed when I noticed it getting harder to put into 3rd gear. It didn't grind, just felt locked out - but a few tries and it worked. Then, when turning around to re-run a long stretch of country road, I couldn't get the shifter into reverse. It felt like when the "preventer" solenoid locked it out to avoid damage when moving forward. It has not gone into reverse since and I tried everything I could think of (shutting vehicle off, cycling gears, etc...). I took it to the dealer yesterday and the latest notice I got was that they had to pull the tranny and are in the process of taking it apart to see what the problem is. To me, that rules out something simple and external like solenoid or linkage issues, and I'm not very familiar with the way transmissions work internally. Anyone else had similar problems or have anything I should pass along to the dealer to speed up the process? I have a business trip next week and I sure as hell don't wan't to do it in the stinky Grand Prix they gave me as a loaner.
I appreciate the help & I look forward to getting involved more in what looks to be a great online community.
