Towing a trailer with automatic leveling system
I do the same. Hitch and adjust with the ignition off. Your manual should have instructions for hitching with a weight distribution hitch. My 2016 manual says to adjust the weight distribution system to make the front fender opening height the same as when unhitched. This keeps an...- RobH

Safely long-haul towing with a 2006 Z71 Tahoe
My transmission went south on me during a trip from Texas to Florida to Pennsylvania and back to Texas in April. It became very apparent in South Carolina. I got a fluid flush which helped for a little while. I changed to driving at 2000 RPM at about 60 MPH on the interstates and nursed it...- RobH

My Experience Towing with a '17 Suburban 5.3L
I would speculate that your weights that are labeled on the weight ticket as Steer Axle -- 7780 lbs Drive Axle -- 6080 lbs Trailer Gross -- 13,860 are actually Surburban -- 7780 lbs with both Suburban axles on the front pad Trailer -- 6080 lbs with the trailer axles on the second pad where...- RobH

2016 Yukon/L680 Transmission upgrades for HD TOW 2016 Yukon XL
With a "tune", you can disable the AFM electronically in the Engine Control Module/computer (ECM). Basically, the ECM reads a parameter/settings file when the ignition is turned on. The file tells the ECM how to manage the engine. A tuner program reads the ECM settings file, edits it, and...- RobH

2016 Yukon/L680 Transmission upgrades for HD TOW 2016 Yukon XL
Welcome to the Forum. Does your Yukon have the "NHT" option code for the Max Trailering Package and "GU6" for the 3.42 rear axle ratio on the sticker in the glove box? Without NHT and GU6, the maximum combined vehicle and trailer weight is 2000 pounds less. It's in the fine print in the...- RobH

Cloud feeling Suspension?
BG1988 said, "the smallest rims on a NNBS tahoe is 17" that means you would need 265/70/17 to be equal size to the 18" 265-65-18 i don't think 15" tires fit on a 17" rim." You are correct on the tire sizes. I edited my earlier post. I must have been really tired when I made that post...- RobH

214K 6L80 rebuild before TCC failure
With my 1995 OBDI Caprice 4L60E, I did something like this using the TunerCat software. I was a lot happier with the results in transmission behavior. And I believed that I was helping longevity of the transmission and engine by reducing transmission up and down shifting and engine lugging. I...- RobH

Cloud feeling Suspension?
What is an XFe? In general, lowered suspensions have less suspension travel. So unevenness in the road is transmitted more abruptly to your backbone. Starting around 1970 off-road motorcycles and racing trucks and sedans started converting to longer travel suspensions and shocks to keep tires...- RobH

If you ensure you have the lower 70 Degree Centigrade Thermal Bypass Valve (transmission thermostat), you may be able to significantly delay the inevitable.- RobH

Slipping or stuttering in 4wd auto mode -- is this normal?
When my tranny torque converter lockup clutch started going out, it was slipping and grabbing in some gears, primarily second. No codes. Did a full fluid flush. Eventually there were codes and a reman transmission. I'd really watch it closely your next miles until you exit your warranty...- RobH

2011 Chevy Tahoe. Z-71 4X4.
Welcome to the Forum. Someone else may comment on this concerning the 2007-2015 Tahoes. My Tahoe fits in the 2015-2020 date range so I am not sure about the 2007-2014 Tahoes. You probably have a 6L80E transmission: 6 forward gears, installed Longitudinally, 80 series, Electronic control. The...- RobH

I got a GM reman 6l80 put in this week. I told the service advisor I wanted the service bulletin bypass valve. I was charged $88 for part # 86774933. I don't know if they happened to have some in the back or what. A December, 2021 copy of the service bulletin is attached below. There may be...- RobH
