I just got my Yukon back after $3500 worth of transmission repair. What are the chances? I've had 2 Yukons (2002 and 2012) in the past 17 years and they both experienced the same problem. Both transmissions went out around the same mileage, about 150K miles!!!! The repair shop said XL version was brought in for the same issue while mine was being repaired, similar model year and color as mine too LOL

Have others experienced the same type of issue?

I replaced my 2002 with a 2012 and upgraded to 4X4. I've always taken care of my cars and have had other foreign makes and models last me much longer without these type of issues. I've always like the design of the Yukon over other SUVs, but this will likely be my last. With both, I've had too many major repairs besides transmission issues and other quality issues too. They've cost me too much money to own beyond purchase price.

The only reason I repaired this 2012 is because I'm giving it over to my teen son to take to college and finish running it to the ground. Hopefully it will last a couple more years before another major issue happens. Oh, but I already have something I should probably repair, bad driver side motor mount.

The transmission on our 2007 got replaced at 160K. Put a GM certified transmission in that came with a 100K warranty on parts and labor. Still going strong when we traded it in at 300K. Wish we would have kept it in retrospect.

Did you buy these Tahoe’s new? Did you change the trans fluid and filter out every 30-40k? A 4L60E and 6L80E are hydraulic dependent systems that require an extremely clean operating environment. Also, exposure to extreme temperatures, even briefly, can have severe consequences. Several years ago I worked as a medical contractor at Chrysler Proving Grounds. I was nosey and bored and bothered the staff a lot. They would let me hang around when they worked. The Mechanic-Engineers could “shred” a transmission in about two minutes. Even the bulletproof Mercedes G56 or ZF S6-650 manual would die after three hole shots. These guys were literally pro’s at destroying powertrains but it doesn’t explain why you’ve been so unlucky. I’d say it is mere coincidence.

You should add a "never" selection, but then you'd want to qualify that with mileage categories.

Never with mine, 104,900 miles on the clock. Fluid and filter change at 95K. Did I just jinx it? LOL

GM’s transmissions are a known weak point in the drivetrain. That being said I’ve seen a lot of guys here say they are still on the OEM transmission at or near that age, with regularly scheduled maintenance done on them and no problems. So if you stick to the scheduled maintenance on them they can last. My 4L65E died at 86,000 because the previous owner beat the snot out of it and never had it serviced. I’m three years into a rebuild and haven’t had any problems with it. It’s about time for a fluid flush and filter but that’s expected.

The engines Require Extremely clean oil too, Active fuel management

train wreaks on dirty oil.. you can't getaway with it like the non AFM engines....


that is why you always inspect the 8itch i mean hitch and ask if it was used for towing
towing = heavy wear and tear I would pay less on one used for towing minus 2500-3000 on what they are asking.. inspect for repaint on it ....

for towing the oil should be changed every 4,000 miles (unless you get a larger filter ) and 15-20k on the transmission

unless you get a after market setup for the oil (i.e larger oil pan)and transmission filtration..
also an oil and transmission cooler upgrade..... remember you want to keep the temps at NON towing temperatures...


I never hit above 165f in the summer and 145f in the winter on the transmission

2002 Yukon had 8K miles and 2012 was new off the lot. Tran fluid changed and always serviced by dealer for most work except for a set of brakes and some engine oil changes. I do pull a boat several times over summer but well within tow limit.

I bought a 2005 Tahoe new (still have) I changed the oil and filter at 30-60-90 thousand miles. Trans went out at 110,000 So the oil changes that I did was a waste.
But why did it go out? Always overhauled my own trans, before but getting to old to crawl under the car. Had Chevy install a rebuilt..
I think it was just one of the valves, or celenoid in the valve body hanging up. I will never know.
