I've got a question for the resident trans gurus - I have a customer with a 4T65 and P1811 code that it surging under load once warm and the converter locks up. I see varying converter slip on the scan tool and lightly resting your foot on the brake pedal pulls the converter clutch command and eliminates the surge.. So... any chances the converter clutch is still good? Is this usually a clutch issue, solenoid issue or EPC???
Would pulling it and installing the TransGo kit plus the EPC and converter clutch solenoids fix the issue?
