I have a 1999 mercury cougar and when I'm driving on the highway doing 65 the hand goes up to 3 and 4 and the car starts to jerk. I'm scared that's its the transmission please tell me it ain't.
I assume you mean the tachometer go to 3-4000rpms. It very well could be the trans, The torque converter might be slipping. But only way to know is have a local mechanic inspect it. Try 2-3 different ones to get a correct diagnosis and price. How many miles on the car and do you know if the transmission fluid was ever changed?
Yes I have had the transmission fluid checked! I've also had 3 different people look at it. The codes they ran was all different and my car still jerks. They said the intake manifold and the o2 sensor. But after reading everybody else answers on here about their jerkin problems could it be the Transmission Range Senor.
