Ford Mustang TCC Solenoid Q. On a 1991 Ford Mustang 5.0 automatic transmission, where in the world is the torque converter solenoid located? THANKS!

A. It does not have a Torque Converter Clutch (TCC) solenoid because it doesn't have a torque converter clutch. Here it is from the Ford Service manual.

DESCRIPTION:
This unit is a 4 speed automatic transmission incorporating an integral overdrive feature. The design of the transmission features a split torque path in third gear, where 40% of the engine torque is transmitted hydraulically through the torque converter and 60% is transmitted mechanically through solid connections (direct drive input shaft) to the drive shaft. When the transmission is in overdrive (4th gear), 100% of engine torque is transmitted through the direct drive input shaft.

OPERATION:
With selector lever in 1 position, the transmission will start and remain in first gear until the selector lever is moved to another position. In 3 position, the transmission will automatically shift through 1-2-3 range, but will not engage overdrive. In D position, the transmission will automatically select the appropriate time to shift into overdrive (4th gear). The torque converter operation is similar to other types of automatic transmissions, but has an added damper assembly and input shaft for 3rd gear and overdrive.
