On my 2004 2500HD two wheel drive gmc, the truck empty, going under 10mph using engine compression only while slowing and going down hill. I get a shudder which feels as though the wheels are locking up and the back of the truck will hop slightly. Anyone experenced this or is it normal due to the engine compression. I was courious if was maybe the Tourque Converter Lock not deactivating properly also?
Thanks Steve
