Truck doesnt shift after 3,000rpms please help!?
Hey guys i have a 2005 ford ranger xlt and i noticed today when I hit the gas hard and the truck goes to about 3,000rpms and then the truck like shakes and the rpm gauge shoots up to 4,000rpms. When the truck is in park and i hit the gas it goes to 3,000rpms amd then the truck starts shaking really bad. What could be my problem? Please help.
