My 01 has about 700 miles left on the factory warranty and I am
trying to get a clue what could be causing my problem. Greg, you suggested that I check the motor mounts, in a reply on another forum. Motor mounts are fine. During the summer months, my Lightning sees boat towing duty. The truck remains garaged in AZ with my boat, and is primarily used to tow a 3500 boat to and from the Colorado River, about 20 miles each way. In July it's not uncommon to see 115 degree days. After towing the boat a short distance if I stop and put the truck in reverse, the engine speed drops to the 350 400 RPM range and acts as if the TC is trying to lock up. After a couple of seconds, the idle returns to normal. Another way to describe how this feels would be momentary overdrive in reverse. The dealer continues to state that there is nothing wrong, and I would imagine that is because they can't duplicate what I have described. There is no doubt that the problem is related to the temperature spike after towing is extreamly hot weather. What I am trying to avoid is paying for trans work that should be done under warranty. Your thoughts about possible causes of what I have described will be greatly appreciated. Also, is there any safe way to get my trans as hot as it gets in 115 degree weather after towing so that I can demonstrate the problem to my local dealer?
