I just got a car checkup from dealer. They said " I need new gasket for control valve body cover". Is there a help video or instructions to remove it?

Good evening,

I attached the procedure for you below.

The labor time in a shop is 3 hours. I would at least double that time doing it yourself.

Caution:
Support the control solenoid valve assembly around the connector when removing the seal. Excessive pulling force can damage the internal electrical connections.

Not to second guess you. But pan seems accessible without removing all that stuff. It's facing outward behind fan, radiator than bumper. Possibly even removing battery tray and reaching down and remove connector and bolts.

Okay. It's done I pretty much followed most of the steps. With exception of remove front transmission mount and fully removing both sides of radiator hoses. Currently I am monitoring for leaks. I noticed replacement gasket was slightly bigger than the one I took off cover, but it fit. I don't know if that might be problem. I torque bolts to spec. It took whole day. But looking at it now this definitely, 6 hour job or less. Thanks.
