My car drives from my house to the stop sign. It stops rough. When I put my foot on the gas it moves slow and it whines then jerks. I have to keep pulling over to make it stop. It keeps jerking and the car has stopped running. I just had the input and output speed senors replaced and I also replaced the throttle position senor. Is there anything I can do to find out if the transmission just need service or do I need to replace it. Yesterday I smelt some burned. It was only brief.

While driving i am Watching the rpms it goes from 1 2 3 as I accelerate but doesn't feel like it shifting gears Can someone help
Not fixed yet but 65 mph and gear slipped to 3rd and wouldn't shift back up. The error codes generated were P1529 and P0720, I'm hoping to replace the Output Speed Sensor and hope that helps.
No reverse, stuck in 3 rd gear. Replaced speed sensors still no reverse, drove OK for a mile stuck in 3rd again.
Transmission won't shift gears/CEL on
when i drive above 20 mph and then come to a stop when the tranny is coming down from gears and right on 20 mph it makes a sudden stop. Does anyone know what would cause this on the tranny, im thinking that its either the input or output tranny sensors.
Cold Start it shifts OK and I can drive around for hours till I turn off car then it sticks in second till I shut it down & it cools completely.
Check engine light on, transmission stuck in third but car still operates just accelerates slowly and can only safely operate up to 45-50 mph.

Car over heated. Rt/Rr wheel bearing went bad. Check engine light came on. Had wheel bearing replaced. Pulled thermostat. Check engine stayed on. Drove car and now stuck in 3rd gear. Drove 160 miles to get car home. Car engine ran perfectly. Didn't over heat. Upon breaking at low speed (~ 15 mph) car jerked and felt like it trying to slip into reverse. (Felt like the brakes had locked up). This happened only once during the entire trip. Car moderately jerks when shifting from park to reverse or into drive. The slower I shift, the less the jerk. Haven't had the car diagnosed yet.
Ok my 2006 drives well but just say I stop at a stop light and Geen light I go to take off and it like the RPM goes up and then kick in but it not a jerk when it kick back in to take off help ..........
