I have a 5.2 liter, Dodge 1500 truck. I took the pan off and cleaned the valve body. I also adjusted the bands. Now, when I take off, it doesn't slip, but at about 20 miles an hour it locks up the rear tires. What's causing that?
I think you adjusted the bands incorrectly. I recommend consulting a transmission expert, someone who knows Dodge transmissions. It sounds like you're pretty mechanically inclined, so if you pick the transmission expert's brain, they should be able to get you rolling again.
