    Hello Mr. Allison Man...I was just referred to you...maybe you can help...our 2002 Allison equipped DP will "slip" or "hunt" between gears when the outside temp. is below 30 takes about 20 miles or so before it starts to do this and does not clear up or get better. It is hard to keep the coach moving..usually in the 40 mph range...I just let it hunt without pushing the accelerator too hard and head home. I had it to Kansas City area Allison facility the winter of 2003 and they could not find anything wrong using their little hand held computer. They did not drive it. They said it could be a Freightliner problem with the wiring harness. I really don't think they believed us entirely as they kept saying they have never had one do this before. Can you give me some ideas to take to them about when I take it back in this month(warranty is getting close)? By the way, it does work perfectly and shifts perfectly when the temp. is warm outside. Thanks, Larry
