I've got 2.25" level up front, and 275/60/20's now and i'm rubbing the UCA's as well, and looking at wheel spacers - Steve, what brand of spacers did you get?

Found it in this thread: You'll need to read through the first few pages to get the idea of what to do. Deets for the cargo lights are in there.

Oh and picked up a Range device as well... the V4 noise was noticeable and 'some-what' irritating after the exhaust mods, but not huge. Found a used Range for basically half of new and gave it a whirl.... actually fairly impressed with how well shifting has improved with V4 being disabled.

Fog lights on with parking lights - DONE Cargo lights on with reverse lights (so that unlocking from the remote turns on the cargo lights in the bed) - DONE Soft fold tonneau (pulled from a trade at the dealer) - DONE Stone deflector (added at dealership, part of the deal) - DONE Weathertechs front and back (referral deal with dealership, only paid for the rear) - DONE Full tint - back added additional 35% to factory to make near-limo tint, front driver and passenger just a straight 35% - DONE MBRP polished stainless exhaust tip - DONE Custom cat-back exhaust - Borla XR-1 muffler to replace stock and resonator deleted - DONE ProComp 2.5" level kit in front, 3" ReadyLift block kit in rear - DONE Pioneer 10" TS-W261S4 350W subwoofer w/Rockford T400-2 400W 2-channel amp (used an AudioControl LC2i to get line level audio out of stock stereo) - DONE Custom 12V power port in the box near the tailgate - wired into the 12V supply line from the trailer 7-pin connection at the bumper - DONE To Do: USB charge only ports for rear seat (install into back of armrest/console) Black bowties Multi camera interface to add cameras that can display on factory screen, with sideview cameras and front camera. aFe Momentum GT Cold Air Intake System w/Pro DRY S Filter and..... some new tires (stock Goodyears are 'poop') - likely BFG KO2 275/60/20 (increasing size to 33" to take advantage of lift)

I have this all the time.... I had taken it in to my dealer and there was a software update for the trans, which they applied - it seems to help a 'bit' at first (definitely not a complete fix), but after a bit of time (oh say a few weeks), I couldn't really tell any update had been done. My "fix" would seem likely a bit extreme by most here, but I've just traded for a 2018 LTZ Z71 (that has the 8-speed by default) and with a test drive, I found a HUGE improvement in the trans response on that 8-speed. I know the 8-speeds of 2014 through 2016 or so had plenty of problems, but the 2018 LTZ Z71 I drove was surprisingly perfect.
