I took my 2007 Jeep Grand Cherokee to the AAA Auto Care Center

Customer Question

I took my 2007 Jeep Grand Cherokee to the AAA Auto Care Center this morning for an oil change. The check engine light was on, so I wanted them to check the code. The guy called me and told me that it was the electronic shifter module and that it would be 655 for the part and 189 for labor. Is this a frequent problem for Jeeps? This morning and a couple times in the past, my check engine light has come on and all of the gears lit up. I resolved the problem by shifting down and then back up. I would rather not pay for a part that needs to have the software upgraded. Any advice?

This is a common problem and the fix is to replace the shifter module.

 

If the car has less than 36,000 miles on it then it will be covered under warranty.

 

If more than 36,000 miles then call Chrysler and complain and ask for help paying for it as it is a common problem and most times they will help you.

Thanks Jeff...is this a DIY easy fix? Do I have to get the part from Chrysler or can I get it through an OEM source?
Expert:  brownjeff replied 5 years ago.

The part will need to come from the dealer, but is a DIY fix. I will attach some information to help.
