2010 Chevy Colorado Crew Cab 4x4 Z71 V8
I had no idea the power would be reduced in 4 low. That’s absolutely stupid.Quick day trip through the mountains south east of Kingman, AZ. Checked out the Gold King Mansion. Trails were super fun with some technical spots. Lots of flexy spots and some decent rock crawling. Even scraped a few times, taking a couple of the optional "Pro Lines".
I'm sad to announce that the truck still sucks balls in 4LO, from a stop, even with the 4.56 gears. I got into a spot where I needed the truck to climb straight up about 2ft. Foot went to the floor and she didn't move an inch. I fkn hate the damn 4Lo tune in this thing. I managed to get her moving by bumping into the climb, but still... a 57:1 final ratio in first gear/4LO should easily roast all four tires when you floor it. I literally had zero power with my foot to the floor. I could probably have made the crawl in 4HI, as it doesn't reduce power, but didn't think about trying till after we were back on pavement. Much disappoint. I need to figure out how to shift into 4LO without the truck knowing, and subsequently be able to engage the front locker as well, since it's a 4LO feature. I'll take a quick DTC code over zero power any day.
Here's the single pic I took today.

I can’t imagine having no power in 4 low.
