If I was below 1K and in drive or reverse, the car would bog down and stall. I thought I was gonna have to have the car towed home, but I managed to get the car rolling by revving to 4k and 5k in neutral and then dropping it into gear. The momentum got the car moving, RPM's stayed high enough to prevent the car from stalling. Shifting, especially downshifting manually seemed to aggravate the transmission and would cause the "stalling" symptom to return. I was able to reproduce the problem on demand, all i had to do was drive it like a manual

Anyway, dealer has my car...says they're gonna replace the transmission under warranty. They haven't said what the problem is and I doubt they are going to diagnose it to figure it out. I want to prevent this in the future but I don't know if this is my flex plate or something else. So I'm hoping your experience might help point me in the right direction so i can spend my money wisely on this.

This is actually my second transmission, the 1st one got replaced Sept 2013. The way this is going, I'm sure it will happen again.

I pinged Megan370z and he seems to be in the same boat with the 7AT, except i think he's gonna throw in the towel on fixing it and just swap it out for a 6MT.

I called GTM about the flex plate seems it's just checmically treated to better withstand the heat, I ahve no idea if it will fix my problem or if I need their torque converter or maybe something else.
