I have 2 questions if someone could help, id appriciate it.
I have a 95 Jeep Grand Cherokee Laredo 4.0. My first question is that when im coasting down a hill, the tach will rise and fall and it speeds up and slows down. i also get a hestitation with normal driving. i've changed the plugs, wires and everything. still didnt help. second question is a transmission question. when im going up hills, the transmission feels like it always wants to stay in overdrive, like going up a hill in 5th gear in a 5 speed car. i have to let off the gas then push it back down for it to drop into a higher gear. i've changed the filter and tried that Lucas transmission treatment and still happens. anybody know whats up? thanks.
