I'm having a problem with the transmission in my 2500 Silverado HD. It is a relatively new transmission. The problem is when the transmission shifts into overdrive, it kicks hard repeatedly like its trying to downshift. It only does this in overdrive. I usually drive it in tow/haul mode or just keep it in 3 low so it does not do that. Could this be a timing issue or something worse? Hope I can get some help!

Thanks
