Q: Jerking reaction when accelerating

asked by on

Mr car a toyota Ceres when driving it would slip outt of gear and bucks especially heading for hills at times it won't move at all then I would have to restart the vehicle until another like 20 minutes or so it acts up again an now it only goes in reverse an not going forward and an also makes their wiring sounds as if its straining what can be the cause for this?
My car has an automatic transmission.

Hi There, What you are describing sounds like possibly a bad speed sensor or potentially a faulty transmission control module, which also controls the speed sensors. The transmission control module has various sensors such as vehicle speed sensors, wheel speed sensors, throttle position sensors, turbine speed sensor, and transmission fluid temperature sensors that all direct information to it in order for it to perform it’s function. Other functions controlled by the TCM are components such as a kick down switch, traction control system, and cruise control module. Any of these may also affect the way the transmission control module performs and controls the transmission and the shifting of your vehicle. A faulty transmission control module may cause also cause a delay in acceleration or erratic shifting of gears. Lastly, this may also be a result of low transmission fluid. I would suggest having a professional from Your Mechanic come to your location to properly diagnose your transmission problem.
