i noticed yesterday that while i was driving on the highway, that my car wouldn't shift gears while accelerating. it just stayed in first gear. I was going 60 mph but i noticed that the RPMs were around 6000 or so and it was never shifting. I checked the transmission fluid but noticed that it was kinda pinkish. it wasn't bright pink but it wasn't burnt. i didn't know what to think it could be.
My car has 150000 miles.
My car has an automatic transmission.
Is the Check Engine Light on? You checked the fluid quality, but was it at the proper level? A shifting malfunction can sometimes be caused by a low transmission fluid level from a leak or a failed electrical component of the transmission assembly like a vehicle speed sensor. If you would like to have this checked, consider YourMechanic, as a certified technician from YourMechanic can come to your car’s location to diagnose the shifting issue.
