It's a good idea to replace the seal for the OD solenoid plunger on the housing while it is out. If oil gets into the solenoid it will cause problems. You can take the cover off and check the contacts and clean if needed. To test the solenoid operation, ground the base, apply 12V to the #4 terminal. It should click in and stay in. The seal number is 3060CR, Napa should be able to order it for you.
