Chrysler cirrus limp mode

1995 Chrysler cirrus in limp mode. Scan shows ecm code 66 and tcm code 60. Local mechanic has replaced input and output sensors on tranny and also tried switching out both tcm and ecm (PCM?) modules. When stored trouble codes are cleared car will run O.K. for a while but then erratically go back into limp mode. Would like to keep the car (95,000 miles and good engine) but don’t want to spend $1,000s on it.



HELP!!!

Take it to a reputable transmission shop.
