Hi partsguy
Mine is doing it intermently and I have no Air Raid cooler. I'm going to talk to dealer after weekend. It will hesitate and make a noise like it is hung in that gear at first and then briefly slows down shifts and takes off. It just started it a couple weeks ago and has done it only 2 times. Mine wants to do it on a firm acceleration or hard. If I'm just coasting along it shifts. I'm trying to remember but after thinking about it it seems to be at redline in that 3rd gear only. If anyone has ideas let us know. Come on Hummertech tell us what is happening.
Thanks for any help
TAZ (Rick)
