What causes a P0613 Code? Replaced TCM 2 times.

What is your question?

P0613 code. Took car to transmission shop. They replaced the TCM with an after market unit. Took a week to get and had to be programmed by Chrysler. Failed the next morning and went back into limp in mode and displayed P0613 code again. Repair shop replaced TCM with Chrysler OEM part and had them program it again. Failed 5 hours later. Same P0613 code. Back in the shop at Chrysler. I can turn off power and it resets after about 2-3 shutdowns. Transmission shifts smoothly after reset. Pulling my hair out!!!!!!
