Hi, Critterfoot and TY for using 2carpros

Try scanning the computer for code/s if any present comeback with it-

NOTE:

Stored DTCs may be retrieved from PCM memory using a factory recommended Tech 1 scan tool or aftermarket scan tool. DTCs CANNOT be retrieved by grounding 16-pin Data Link Connector (DLC). Plugging scan tool into DLC, located under instrument panel, enables user to read DTCs and check voltages in system on serial data line.

There's no other transmission than the 4T60E on those vehicles
