Ok was driving the LBZ today shopping and pulled into a lot and felt the truck still pushing even though I was not on the throttle. When I stop at a sign or light it still tries to push through the brakes like the converter is not unlocking. When i finally got home and put it in reverse and said shift range inhibited. Shut truck off and restarted and it would go into reverse but still felt like the converter was locked up. It would spin the rear tires while stopped on gravel and same in D. Any Ideas? Was serviced sept 09 but only has about 7k miles on it since and no hooks.

I'm going to check and make sure my wonderful little dog didn't chew on some wires and they finally broke today.
