Q: Transmission

asked by on

Got an oil change and my check transmission light came on

My car has 169289 miles.
My car has an automatic transmission.

Hello. The check transmission light comes on when the computer detects an issue with the vehicle’s electronic transmission control system. Unless the oil change included the transmission fluid it is not likely that the issue is related to the oil change. I would recommend scanning the computer for trouble codes, as they will likely reveal some insight as to what the issue may be. It may be possible that a sensor or component that is a part of the transmission or computer systems, such as a speed sensor or transmission solenoid, has gone out and needs to be replaced. If the vehicle does not appear to be suffering in performance that is a good sign. However I would have the vehicle looked at, or the codes retrieved, as soon as possible to avoid the problem from potentially progressing into a bigger issue. A certified mobile mechanic from YourMechanic can come to your location to inspect the transmission light.
