The shift solenoids are all the same, just different locations.

The side cover has to come off, which means you need to drop the drivetrain down enough for the cover to clear the frame rail. This is beyond your average DIY'er.

Start by doing a trans filter and fluid drop, possible you just have contaminated fluid.

When you have it apart you can test the solenoid by applying 12v to it. If its clicks, it's good and you'd need to further investigate your problem. Check that the valve moves freely in the bore.
