Q: Q: Transmission not shifting properly

asked by on

2003 Dodge Grand Caravan. My transmission has been occasionally shifting roughly. Made an appointment to get the screen changed, but before getting there, the engine is revving high and not shifting into the next gear.

My car has 190000 miles.
My car has an automatic transmission.

Hi There, This can happen for a few different reasons such as low transmission fluid or a faulty control solenoid. An automatic transmission requires hydraulic pressure generated by the transmission fluid that gets pushed through a series of chambers inside the transmission, activating solenoids that cause the transmission to shift at specific intervals. These intervals are controlled by the transmission control module which reads input from transmission speed sensors to determine the rotational speed of the input and output shafts in the transmission. Based upon this information, the control module directs the transmission shifting function. When any of these components are not working properly, you may notice an erratic shifting of gears or in some cases the transmission may not shift at all. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.
