Hotrod -

After all of the additional discussion, here, I'm thinking that your best first step would be a fluid change; while you're ate it, clean the governors, which can be done with just the pan off. Though it could be something else gummed up, fresh ATF may help break up what you can't clean without a complete disassembly - surely, worth a try.

You're gonna have to drop the pan to check the torque on the valve body bolts, anyway.

However, don't mess with any adjustments until you've read the shop manual procedures AND checked all the related bulletins for updates.
