Towing a 21 with 4 speed transmission
We have a 2001 GMC Yukon XL with a 5.3L V8, towing package (including transmission cooler), and 3.73 gear ratio. Towing capacity is 7800 lbs. We bought it new and it has been pampered - only 100k miles and very well maintained, so we know it’s in great shape. There are also things I can upgrade (like brakes) that will improve the towing experience.
My concern is the 4 speed transmission, as our travel plans include trips through the mountains. Any feedback on towing a 21 (either C or NE) with a 4 speed?
Thanks much for any input provided!
