2013 Chevy Silverado 1500 4x4, about 45k miles. Pan drop, NAPA filter with Supertech Dex VI. YouTube videos indicated the back of the pan wouldn't clear the exhaust crossover unless you jury rigged a device to pull down the exhaust. I wedged a 2x4 in and drove a couple of shims in to get clearance. Still took a bit of work to get the pan to clear.
Putting it back on, I was smart enough to remove the dipstick, lol. Slid on like a champ. Now, I wonder if the clearance issue would go away if only the dipstick was removed first.
Fluid didn't look bad, magnet only had a coating of very fine metal on it. No other metal in pan, and the bottom was clean. I've been a disbeliever in doing fluid transfers instead of pan drops, but in this case, I'm not sure the pan drop with filter change was necessary. I do know GM calls for it at 45k with severe service, but the dealer only wants to do fluid exchanges. Guess like other dealers, they are tired of returns from leaking tranny pans caused by techs being in too much of a hurry to torque the pan bolts correctly.
