#122 of 164 07 Yukon Transmission Hammering/hard Shifting issues by cjsly172

Jul 09, 2012 (3:30 pm)

Hi all,
 
I had my transmission serviced (fluid flush) last June on my 2007 5.3L GMC Yukon. At the time it had approximately 55k miles and today has 64k miles. A few months later I started to experience very random transmission issues that have recently become more persistent. The first issue is the transmission seems to hammer when the car rocks back when coming to a normal stop (It doesn't always do it when you come to a very slow stop). Once it has hammered after the stop, it will do it again within a second or so after accelerating.
 
Now it seems to be occasionally shifting hard between first and second and/or second and third gear. I have stepped on the gas a few times to experience either a hard shift or an initial dogging of speed until I get in an upper gear.
 
Has anyone had a similar experience? What did you do to resolve this?

I have a 2008 Denali XL that has been the best ROAD CAR that I have had. I have run 100000 miles in 4 years between Oregon and California. However GMC planned obsolescence has kicked in as it neared the 100000 mile mark. Gauges started behaving mysteriously, going off, coming on, temp - drive indicator off brake light on when it is not set?? Ball joints went out, front end repairs. Door actuators needed replacing. Now tranny or differential from 35 MPH up makes a whine and is getting worse. The hard part in all these problems is knowing when to cut your losses when a similar replacement vehicle is in the range of 60K. I guess if you replace everything for 30K you make out. Cars are a losing proposition.

You're not alone on this. I made the fatal mistake to try again with GMC. We first bought a 2002 GMC XL Denali. At about 56,000 miles the transmission dropped. Called GM and asked for them to help with the transmission since it is inexcusable that you pay this much for a car and at 56,000 miles the transmission goes? Would not budge. I have 4 kids so I need a reliable car and we don't want to buy a mini-van. 2 years ago we traded that in for a used 2007 GMC 5.3 XL just like yours. While looking someone mentioned that GMC and Suburbans are known to have transmission issues at around 55,000 miles. We ignored the warning and bought the 2007 GMC Yukon SLE XL. Like you we are starting to get the hammering issue with the transmission at 65,000 miles. When we accelerate from a stop position it hammers (bangs) or jumps into gear. I'm sick over this car as we can't afford to pay $3,000 for another transmission. I have never experienced a vehicle that has so many predictable issues. Even before this I was so paranoid that I swore I felt the slight hammering at about 50,000 miles and asked my mechanic and he could not detect it. I'm not sure if this will save me from paying for the fix since they have it in the system, but I'm sure they will weasel out of it somehow. I also had a steering fluid leak back at around 52,000 miles and GMC did honor the fix as it was close to the warranty. I'll give them that but for a car like this to have issues is ridiculous. I should have learned my lesson and not bought a GMC again. I have zero faith in this car or any GMC or Suburban and feel like I could break down at any second. I go on vacation with my family and I'm always praying we make it back and don't break down on some back road. Whats worse I'm concerned my wife and kids don't have a reliable vehicle and could breakdown somewhere. With such a big family (6 of us) I have few options other than a minivan. One thing I do know is I'll NEVER buy another GMC or Suburban again if this 2007 has yet again another transmission problem. A Ford Excursion or Range Rover L4 can't possible be worse. BTW, If a class action does develop I'm on board.

I did get the following reply from Christina 7/27, but I have not heard from anyone else yet, neither phone or email.

Another one here. I have a 2003 Yukon XL with the exact issue you mention about punching the gas and the rpms surge but no acceleration. I'm trying to get prepared for the $3500.00 expense to replace the transmission. My truck only has 74k on it. This is absolutely ridiculous that a $45K vehicle can drop a transmission after 74K miles. I really wanted to keep this vehicle for a lot longer but after seeing all the failures here I think I'm going back to the imports!!!
