Q: Transmission does not shift properly

asked by on

my tranny has been acting up. It jerks into the first two gears and delays form first to second gears. Was also disengaging while delaying from three to four.It also jerks when coming to a complete stop

A: This may be a result of low transmission fl...

This may be a result of low transmission fluid or potentially a faulty transmission control module. A faulty transmission control module may cause a delay in acceleration or erratic shifting of gears. 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 components 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. I would suggest having a professional from Your Mechanic come to your location to properly diagnose your transmission shifting problem.

Unless the fluid is obviously contaminated, and thus there is a possibility of a blocked transmission filter, I wouldn't start the diagnostic with a fluid/filter change. Eventually, you should change the fluid and the filter but more likely causes of...
