Buy this quality rebuilt solenoid pack that fits PWM type 4R100 transmissions only. Please check before ordering.
You can measure the OHM's of the lock up solenoid pins to make sure this is the correct solenoid (check the picture).
OHM's should be 10-15 if not, this is the wrong solenoid.
Also the Ford part number is stamped in the solenoid, needs to start with "F8"
This is a PWM solenoid and does not work with an ON/OFF solenoid type.
The solenoid will have a white solenoid with two holes like in the picture.
If you have question please ask.
This solenoid has been cleaned and tested on a transmission solenoid Dyno in hot transmission fluid.
