When driving my 2003 Jeep Liberty Sport the engine started revving, but the car only moved because of momentum. If I pull over and restart it is fine for 50-100' then does the same thing. I had to put it into 2nd gear to limp it in to the dealership. The engine light came on. The dealership claims it has 2 errors, one of which is error after shift, and needs a transmission. The car only has 100,000 miles on it, barely, and is regularly maintained.
