Were on the 1985 ranger auto trans 4spd is the t/c clutch plate solenoid?
I heard on some cars its in the trans.
I want to test the solenoid, & it has to be removed to test.
Here is the tech. article on the part Im looking to find on my ranger:
The hydraulic lockup that occurs is not the same as the mechanical lockup that occurs in a torque converter equipped with a computer-controlled mechanical clutch. Because there is no mechanical connection between the impeller and turbine wheels, an ordinary torque converter will experience up to 10 percent slippage between the engine and transmission. This hurts fuel economy and performance, so the torque converters in most late-model vehicles have a computer-controlled pressure plate that locks up against the housing when the vehicle is about a certain speed and/or is in higher gears. A "computer-controlled solenoid" controls the flow of hydraulic pressure from the transmission to apply and release the pressure plate. When the plate is engaged, there is no slippage between the engine and transmission, and the torque converter acts like a solid member in the driveline. But when the brakes are applied or the vehicle is idling with the transmission in gear, the pressure plate is released so the torque converter can slip.
