I’ve got a 2018 GMC crew cab Z71. I’ve got a 2.5” level on it and it’s still about .75” lower in the front than in the back. Is there a small lift I can do to get it closer to level (no squatting) and maybe a little higher overall (maybe like an inch or so so my 34” tires won’t rub)? Ideally I’d like to keep the same ride quality I’ve got now.

And today GM called me (?!) asking for an update, because they apparently have no clue what is going on and were not aware I’ve had the truck back since beginning of last week. Sent from my iPhone using Tapatalk

We’ll never know what the issue is, as they ended up replacing the whole transmission. Thus far it seems to be fine judging by the much lower temperatures (and much slower climbing) driving around town. Will hook up the boat soon and see what happens. Sent from my iPhone using Tapatalk

Yea I have an escalated case open with Customer Care now as this has become a bigger issue since at this point I have a 2018 truck that I’ve been without for about 20 days. Sent from my iPhone using Tapatalk

Thanks for the info. Unfortunately, at this point, I’ve had the truck at the dealership three times and it currently is still sitting there with the transmission taken apart waiting on parts yet again. I have no idea if they have checked the items y’all are referring to but I will ask.

This guy predicted it. Multiple trips to the dealer in the last month and still not fixed.

Do you have any pictures or diagrams by chance? The dealer still hasn’t fixed this and actually have somehow made it worse (now transmission overheats in town when not pulling anything). edit - the strange thing is it went over 250 but the alarm didn’t go off this time

Thanks for the info. Truck has been in the shop for one full day so far. Sent from my iPhone using Tapatalk

And thus far today my truck has hit 210 driving around town... supposed to take it to the dealership tomorrow morning. Sent from my iPhone using Tapatalk

Just for reference, father-in-laws 2500 pulled the little boat with the transmission temperature at a cool 185 degrees... Sent from my iPhone using Tapatalk

No brakes, good idea though Sent from my iPhone using Tapatalk

I’m guessing like 1600 for the boat, 400 for the motor. Sent from my iPhone using Tapatalk

Could it still be the thermostat if it doesn’t do it when not pulling the boat? We ended up unhooking the trailer (and swapping trucks) and my truck drove home without the boat in the 195 degree range.

So I just got a new boat (only 17ft fiberglass) and was on the way to put it in the water for the first time and my 2018 GMC Z71 with 10k miles apparently can’t handle that, as within about 15 miles on the interstate I get a warning saying my transmission is overheating and I need to pull over and idle. After a couple of minutes I was finally able to navigate through the control panel it said the trans temp was 258 degrees. I was driving in tow mode. After it cooled down to 210 degrees I tried again without tow mode and it was back to 241 degrees before I got to the next exit about 2 miles away. Needless to say I’m pissed off.
