Hello all-

I have a cl that I love and don't want to give up. Purchases at 150,000. Now at 164,000 miles and check engine light is on. Codes were map sensor (108) and transmission (740). Fixed the map sensor. Put some transmedic in tranny. When starting out cold, shifts pretty well through all gears. When it heats up, won't shift from 2nd to 3rd. And not always great about shifting from 1st to 2nd either when hot. Any suggestions or information to share would be greatly appreciated.

 

Transmission drain and fill, and maybe a new selenoid

 

Thanks for the info. Have you had this problem?
