So I've got a 1999 GTP, fluid looks ok. Level is fine but its acting up.

If in drive or 3 it does nothing. Reverse works fine. But if I shift to 2 or 1 it will drive but shudders if give too much throttle. After getting going and it goes through the first 2 gears you can move the shifter to 3rd, shifts to 3rd fine. Drive a little more, put it in overdrive, overdrive works fines and it flys. No shuddering at all in 3rd or 4th.


Tranny shot? I have heard of PCS issues but didn't think the symptoms matched what I had going on.
