I used to have occasional wonky shifts. After installing my FitzStick, I discovered my level was down 3/4 qt from the factory. Bought a quart of Mercon ULV from a dealer, corrected the level, shifts have been mostly good with a very occasional downshift clunk. I drive mostly in Tow-Haul mode.I had some weird shifting when I bought the truck used 2 years ago. I had to talk the dealer into checking my trans fluid level because I had read here some came low from the factory. It was a quart low and the weird shifting disappeared. $301 to check and top off something they should have done at the factory.
