2018 Compass Transmission PM
Car idiot here…
The automatic transmission in my 2018 Compass has been acting weird more and more frequently. The check engine light will come on, and then I can’t get the transmission to shift beyond 3rd. It’ll max out at 3,000rpm and about 33 mph. I can usually solve the problem by stopping, shifting from drive to park to reverse a few times. Then stopping and starting the engine. The check engine like will usually stay on, but I’ll be able to shift beyond 3rd. I have an OBD gizmo that is exactly no help, as it’ll give me no error codes when the CE light is on.
There’s no dip stick do the transmission, so I have no idea of the fluid status. It seems dumb to have a closed system like this, maybe I’m missing something.
Is there a way to PM my transmission fluid, or transmission itself, without potentially wrecking my car due to being an ICU nurse and not a mechanic?
