I have a 1997 T4R Auto 4x4 that has 130,000 miles on it. It has been a great vehicle. Recently when driving at say 50 mph and kindly coasting then give it little gas it has a hesitation or jerk to it. I've tried to figure if it was the engine or maybe the transmission. I am hoping maybe someone else may have ran across this and know what may be the problem. Thanks.
