I just bought my 97 gtp and for some reason it only will hift into 3rd gear at 48 mph or above. i have a 2000 gtp and never experienced this problem at all, i want to get this fixed but do not want to pay shop rates to have it done. if anyone has had the same or similar problem let me know. i dont know when the filter was changed, i thought it might be that the filter is stopped up and has to build more pressure by getting to a higher rpm to shift but i could be completely wrong. thanks
