722.6 no torque converter clutch lockup
722.6 no torque converter clutch lockup
Has anyone had this problem on a 722.6 before? Do the converter clutches wear out?

If it is the TCM, maybe you can do a factory reset.

I'm wondering if the TCM will log a DTC when the TCC slips due to mechanical fault only. On Fords and other makes, TCC clutch slippage is monitored via engine RPM vs output shaft speed. It's a useful DTC.
Are TCM codes checked through the OBDII port? It's looking like it's time to replace my lost copy of EPC :-(

.6's opperate the TCC as a slipping type of clutch. The TCC do wear out fairly often.... easy to diag by adaptation numbers
