Hi everyone,

I've noticed that the gearbox oil pump on my Sportshift 4.7 Vantage doesn't activate when I open the door. Normally, there's the distinct noise from the pump when the door opens, but that noise is gone.

Interestingly, I can sometimes hear the pump operating when the car is stopped and locked, such as when I walk past it in the garage to get to my daily. I can also hear it when starting the car with the slower process: inserting the ECU, waiting for all dash lights to go out, and then pressing the brake pedal to start.

I've upgraded to a lightweight clutch, and it worked fine for several months after installation. The issue began after a dead battery incident. I replaced the battery, and the pump started working again temporarily, but then it stopped once more.

There are no error messages, and the door switch seems to be functioning correctly since the window drops when I open the door.

I'm not sure if this is a problem or if anyone else has experienced it. Any opinions or advice would be appreciated.
