Took the GTX to go and take care of my Dad. Everything was fine, til I was on my way back home and pulled away from a stoplight. I went from 1st to 2nd, with no problem. Then, when I went for 3rd, it wasn't there?

I quickly tried 4th and IT wasn't there either!

Yep, I had Reverse, 1st and 2nd! The car sits too low and I'm too big around, to be able to get under it to check if the linkage had come off or not. So, I got it home bwst I could (about 12 - 15 miles, with some hills). Got it home and put it up on the ramps. The linkage is intact and moves like it is supposed to. Jacked the rear up, had Joey turn the wheels to see if I could go under the car and make it go into gear?

Nope! So, now I'm draining the trans to pull the side cover and see what happened. Never been into a car trans before, but I'm hoping a pin has come out in the shift mechanism in the side cover. Any input, would be appreciated. I will be in and out, til I get the cover off and see what happened.
