Ok so ive done a little research and am confused as to what could be my problem with my tranny. Its in a 2003 GT Symptoms: about 10k miles ago every now and then the tranny would shift from 1-2, 2-3 really hard and then if you shut it off and parked it for a bit it would be fine. it has done this on and off for the past 10k miles and i just figured it was me getting on it and the computer setting it like that. well last weekend it did that and on monday when i started it and started driving it acted like it was low on tranny fluid, car would start moving but the rpms would be way out of normal range like i could be going 10mph and push the pedal half way down and the rpms would shoot up to 3-4k. the transmission will shift very slowly from gear to gear if you dont let the rpms go over 2500 and when it does it usually jerks a little. When the car has been warmed up and driven for a few miles it is fine, shifts normally. I have already checked the tranny fluid its clean and at the proper level. Ive read that the shift solenoid could be the culprit as well as a pressure solenoid (which makes more sense to me) but i would like some more opinions on it. It has 122k on the car and has been maintained by the book since the car was purchased in 2003.
