My wife’s town and country had its serpentine belt replaced. Now it won’t go past second gear and is running 3.5 rpms at 40 mph. What do I do?
Coach, You Sure Have Your Share Of Car Problems.
What Do You Do?
It’s Like Saying “My Foot Hurts, What Do I Do?” That Depends…
I Don’t Think The Shifting Problem Relates To The Serpentine Belt, But Take It Back To That Mechanic And Ask For A Diagnosis.
Check the fuses if the power distribution center. There should be a fuse titled ‘transmission’ or transmission solenoids’. If this fuse opens, the transmission goes into ‘limp home’ mode which is Reverse and 2nd. It is a cheap fix for a sick transmission.
If this does not help, have a capable transmission specialist scan the Transmission Control Module for codes. If the TCM has a problem with a sensor or otherwise cannot decide how to drive the clutch valve solenoids it will revert to ‘limp home’ mode.
I am not sure what year your car is, but certain generations of these are prone to the shift solenoid going bad. It is $100 part and easy to change, so make sure you don’t pay for a full overhaul unless you have 2-3 opinions.
