I was wondering if you could tell me the towing capacity of my 2008 Yukon SLT 5.3L V8 VIN#: 1GKFC13J38R159666 (no flex-fuel)
I have towed a 4800 lb travel trailer approx 100 miles (one way) and noticed that my Yukon usually has a temperature of 210 degrees (even when not towing). However, when I'm towing the TT, as soon as I start any kind of hill or grade I can watch the temperature increase. I also noticed that the Transmission temperature increases as well...up to 232 degrees. Once I started back down the hill or grade the temp quickly returns back to the 210 degree mark. According to the RPO code and owner's manual, I have 3.73 gears and a towing capacity of 7500 lbs. However, I have read several other articles that state I only have 6500 lb towing capacity. Was wondering if I should be concerned about the fluctuation in temperature or if this is to be expected.
Also, should I tow with the "trailer" button on or not?

I understand your concern; I wanted to confirm with you that per GM the maximum trailer weight for your vehicle is 7500 pounds. It is also important to take the Gross Combination Weight Rating into account - essentially, the combined weight of your vehicle, cargo inside the vehicle itself, and the weight of the trailer should not exceed 13,000 pounds.
The Tow/Haul mode on your Yukon adjusts transmission shifts while hauling, making them less frequent and more predictable. This can perhaps be very noticeable on downhill grades.
As far as the fluctuation in engine temperature, engine coolant at higher altitudes will boil at a lower temperature than at or near sea level. If you turn your engine off immediately after towing at high altitude on steep uphill grades, your vehicle may show signs similar to engine overheating. I am not sure what altitude you are driving at, but thought that this might be useful to you.
I am going to ask our Technical Assistance Center about the fluctuation in engine temperature you mentioned, just to make sure you are within a healthy range and that this is normal. Once I hear back from them, I will be sure to relay this information to you.

#32 of 54 2007 Yukon Towing Capacity
Apr 24, 2012 (6:52 am)
My husband and I have been looking at buying a travel trailer. We could be towing it with a 2007 Yukon. When looking online for towing capacity it changes with each website we look at- some saying only 4500lbs and others saying up to 7200lbs.
Just wondering what is the maximum weight the 2007 Yukon can tow?

The following is the response I heard back on the fluctuation in temperature question:
Please see excerpt from owners manual page 3-47:
“It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210°F (100°C) or less. If you are pulling a load
or going up hills, it is normal for the temperature to
fluctuate and approach the 250°F (122°C) mark. If the
gage reaches the 260°F (125°C) mark, it indicates
that the cooling system is working beyond its capacity.”
I hope this helps!

#35 of 54 My husband is in a panic!!
May 18, 2012 (8:38 am)
We traded in our Ford Excursion and bought a 2011 GMC Yukon XL-SLE (i know.. big downgrade) anyhow, now my husband is in a panic thinking our Yukon XL wont tow our 25' boat. Boat weight is 4300lbs, with about a 1,500lb trailer - total tow weight is 5800lbs. He's afraid it's gonna be a total dog and not be able to pull the boat.. We also will have a full car - packed with kids and all their "kid crap". Should we be worried we've made the wrong choice?? Vin# 1GKS1HE07BR265482

Given your VIN, I found the following. I know it is a lot of terminology, and I hope that I can communicate it clearly for you!
The Gross Vehicle Weight Rating (GVWR) for your specific vehicle is 7200 lbs. This is the maximum number of pounds a tow vehicle may weigh. Everything that contributes to the weight of the tow vehicle is featured in this rating, including the weight of the vehicle, driver and all passengers, fuel, payload, trailer tongue weight, hitch weight and all optional equipment. The GVWR is displayed on the driver’s door or door-lock pillar label of your vehicle.
The GCWR (Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer including any passengers, cargo, equipment and conversions; the GCWR for the vehicle should not be exceeded) for your vehicle is 11,000 lbs and the maximum trailer weight per the owners manual is 5,500 lbs.
It looks as though the weight of your trailer and boat exceeds that of the recommended maximum trailer weight; as far as how this may affect your vehicle, I am unsure. It may be a good idea to speak with your dealership on this matter.

#37 of 54 2007 Denali Towing Temperature
Jul 23, 2012 (9:22 am)
Towing my 7,500# boat this past weekend I noticed the digital readout of the transmission temperature climbed to 227 going up hill and would typically hover around 200 on the flats. Is this too high? Will the cars computer tell me when the transmission is too hot?
It's a 2007 Yukon Denali 6.2L AWD.
Any information would be great. Thanks, MM
#38 of 54 Yukon XL 2008 Trailer Towing
Jul 25, 2012 (8:06 am)
Asked what is the maximum capacity of a 1500/ 5.3ltr. XL ??
Having also bought a 2009 XL with trailer tow option I found the rig came with a 3.42 axle and surprisingly NO transmission cooler. Although the mfg GVW ratings will restrict your 5.3 Yukon XL to 5400/5900#, with an adequate transmission cooler this rig will pull 8500# with out any shift scheduling or engine laboring while in trailer tow mode, however, make sure you have a transmission cooler. I found mixed reviews and also looked at Suburbans and Yukons and some do not have the transmission cooler.
Without this KEY element you can anticipate transmission overheat; I've experienced it!!
Also note the difference of a 3.73 vs 3.42 rear axle can make the total GVW decrease.
** Driving in extended hilly country without the 6.0 engine will place high demands on your engine but of relatively flat roads and moderate inclines you should have no issues.
