Unfortunately there is not a cleaning procedure for these solenoids. They come in a block and I am sure you can take them apart but it is easier and better to just replace this.

Also, it sounds like you have an issue in not only the shift solenoid pack but the reverse servo.

More than likely the fluid is contaminated with clutch debris or metal.

I would start with servicing the unit and checking the fluid.

Then look at replacing these solenoid. Please see the info below and let us know if you have other questions. It would be a good idea as well to check for codes and make sure we don't have anything different to go on.
