The tranny is done. My dad has a 2002 yukon sle with the 4L60E automatic Tranny in it and we were driving on the highway and hear a clunk and then we hear grinding gears. Now the truck is missing Park, Reverse, OverDrive, and my brother took it to the garage today on the way it blew a tranny line and it made the exaust catch on fire. He had the cops following him down the road for a mile or so.

Our 2002 Yukon XL has been having transmission problems. We are now on number 4 and counting... Four Times in the shop for transmission problems.
 
We got our truck back from the last service in June with 49,000 miles.. we now have 63,000 miles and yes... transmission problems again....
  
"Hard Shifting" Code 748 was the number this time.
 
If you are thinking of getting a GMC Yukon .... Good Luck... You will need it...

So, what is the problem this time? Is it the clutch assembly again?
By the way, do you have the 5.3L Engine, or is this a Denali?

i have 2007 tahoe (company suv) with 24000 miles and have the same problem. as a mater of fact i know more then 10 SUV's that had the same problems. also, i own a 2007 yukon with 1500 miles and from first day i notice that when it shifts at last gear and while it is at 2000 RPM(going 65 to 70 miles), i hear a noise as it is not in the right gear and it feles as you riding a stick shift and you driving at wrong gear.

it is the 5.3L, 4X4,SLT. am not sure yet and am not planning to go to the dealer and let them to miss with the transmission unless the car stops completely because most of these service guys in Saudi dealer are not as qualified as the guys in the states.

My 2004 Yukon XL tranny just went out at 80K miles. Never pulled anything...always treated kindly...and boom...the tranny is gone. Really makes me sick. This was a great truck until yesterday. I thought about calling GMC but I know they won't help. Oh well, I am having a Jasper remanufacture installed and will drive till it drops...which may not be too long~!

I have a 2001 yukon denali and it runs great but when I drive the truck for awhile when I go and try to make a turn it jumps. One person told me it was the transfer case. is this true

2007 Yukon Severe Transmission problems by yukon6

Our 2007 Yukon Denali XL had its first transmission failure at 1,850 miles. At 55MPH it came out of gear, would not re-engage until we turned the ignition off and on three times. Limped back to the dealer with only 4 operating gears. The dealer rebuilt it. At 2,430 miles, while in the Sierras outside Yosemite at 2500 feet, the transmission heated up to almost 200 degrees (outside temp only 78), and it came out of gear again. This time it would not shift out of first gear until we let it sit overnight. Drove it back to the dealer. Now they are talking about putting in a new transmission.
 
While at a meeting with some business friends, I found out another 2007 Yukon owner and a 2007 Suburban owner both had the same problem! The dealer was replacing the Chevy transmission at 15,000 miles after the transmission failed, would not come out of third, and heated up so bad the transmission was toasted. The other Yukon owner had a complete transmission failure while on vacation and the vehicle was not drivable. The dealer replaced the transmission. Coincidence or a fundamental design problem?
