I went to get my truck tested because my check engine light came on. They gave me code 632, Overdrive Cancel Switch(OCS)- no switch action detected during Engine Run Self-Test. They said I need a Torque Converter Celleniod. How do I replace this and where is it. I have a 1994 Ford-f150 Automatic w/ Overdrive, 300 inline-six 4x4. I dont know what to do! I need help!!!

 

Did the test operator press the overdrive cancel button while self test was running? If not, that's why that code set. If so, there is a problem with the button or the wiring. It isn't related to a solenoid at all.
