We loaded back up started back out on the road and lost of transmission function in forward and reverse. Turned our 2005 Yukon SLE off and waited for a few minutes and transmission started working again. We never had any signs of transmission problems and had our vehicle checked out before leaving home.
We are now in a hotel trying to come up with a plan to get us back home safety. It appears this vacation is shot and will end up dropping our vacation cash just to get home.
If we rent a van wand a car hauler it will cost us over $1,000 just to make it back to East Texas. My only other option, is leave my wife and kids behind at our planned vacation location which is another 200 miles away and fly back home to get my truck to drag this Yukon back home on a hauler.
I had a 1999 GMC 4X4 extended cab that had a similar problem, however it would at least run in low and reversed worked. Either way, I am in a pinch with no way out unless I open up my bank account. Good Luck to you and hope things work out. Tomorrow is another day in almost paradise for us.
So anyone reading this thread. when you get this thing rebuild I would stonly advise against the oem parts as it apparant they suck. I told my trans guy I would be towing and I wanted it to be bullet proof. he put in a hardened sunshell. a 5 gear planetary ( vs 4 gear stock) upgraded spauges. better clutch pack and a shift kit. Also if you are towning I recommend looking at an upgraded tranny cooler. that is my next upgrade.
I am doing everything I can moving forward from having the trans explode 1000 mi with on vacation. As I bought this vehicle to vacation with.
Sorry to hear about your problem bro. I hope you and your family make it home alright.

Installed a new GM trans and Engine into my 2002 XL Denali over the weekend and when hooking everything back up was confused about the vent line routing. There are 2 long vent tubes that go on the back of the transmission and it looks like one just ends to the open air. Is this correct or is there a place this is supposed to hook in and I am missing it?
There is a barbed vent connector on top of the Transfer case (hooked the shorter of the 2 vent tubes which showed signs of a bulge in it from having a barbed connector in it previously), but the second, longer tube looks like it is held by a clamp over top of the rear output seal on the transfer case and just vents to the open air. On the front of the vent lines, there is a bracket that attaches to the back of the engine block. Seems strange to me that these would be high up and have plugs/diffusors in them yet have an open end on a lower plane at the back of the trans/transfer case.
Any help would be appreciated!
Thanks,
Ken

Took the truck to an independent mechanic who specializes in transmissions and performance shop work. Upon disassembly, he found the 3 / 4 drum was burnt up. According to him, everything else in the tranny looked "pristine" - no dirt, sludge, or signs of wear or abuse. The clutch drum just wore out. He also told me that he sees this a lot with these transmissions. He replaced the drum, put in a performance 3 / 4 band (to increase surface area when the band engages the drum), replaced all the springs, bearings, bushings, seals, and the torque convertor. He also drilled out the valve bodies for 1st and 2nd to give the tranny a little quicker response out of the hole. The truck is as good as - if not better than - new. Total repairs were 2 grand.

As (one of) the latest victims of the bedeviled transmissions on the 04 Yukon :lemon: , I have been searching for a solution that will meet three criteria: 1) speedy repair, 2) inexpensive, and 3) permanent. I have been reading this forum and I have noted that you, as a representitive of GM Customer Service, acknowledged that there is a problem with this product and have confirmed a willingness for GM to fix the problem. But as was stated in a previous post, the $3500 repair job was not cheap, and now that the problem is back, it is NOT permanent. So, please let us, the sorry customers :mad: , know what GM is doing to help fix this problem.
I hope this helps to clarify what I can do as a part of Customer Service. I understand that the process can be frustrating, and I apologize for that.
Best,
Sarah

I appreciate your response as well as your dedication. While I may be a bit cynical, I do believe in the addage "You get what you pay for." The sticker price for this Yukon was on the far side of $40,000! It has had numerous inconvenient problems and is now sitting idle with a bad transmission :lemon: .
Staring down a $3K+ repair bill (not to mention a loss of confidence) makes me think "I did NOT get what I paid for." I don't see how a long history of expensive repairs changes anything. The transmission fails once or it fails three times, it still failed. Nobody is going to say "Boy, those GMC's have a bullet proof tranny!"
My plan is to have it fixed and then sell it.

GM customer service contacted me thru here. but it looks like they are just trying to cover up a known faulty product. yes you can bring it to out facility they said. but if we find no issues you will have to pay ~$800for the tear down. Well of course GM is not going to find no issues with the OEM parts they put in the 46le for the Yukon / XL . Because they suck!!!! and last as just long as they were meant to, that is why you see people complaing of 3 and 4 transmission rebuilds.
So here is my advice if anyone wants it. And I am by no means an expert. but I did do a lot of research before shelling out $2600 because for me that is painfully an awefull lot of money.
Anyway the 46le actually IS a good transmission design. it is found in a lot of different product lines from the S-10 and blazer ( which I own and on 80,000 miles with no issues ( knock on wood)) to the corvette!!!!. and I guarantee the corvette can hammer on the transmission pretty hard.
The problem lies in the components used for the yukon line ( corvette transmission use diffrent internals!!!). Plain and simple. the OEM internal componets used for yukon's suck and are under engineered and obviously judging by this forum to not last very long.
So when I when to my tranny guy. I definately did not pick the cheapest guy. I sat down and told him what my expectations were from a tranny and what I wanted to do. in my case pull a 20 foot boat thru the mountains.
so he DID NOT use oem parts on the rebuild. he put in a hardend sun shell. 5 gear planetary upgraded spragues, larger tranny cooler bla bla bla. all the upgraded stuff will cost a few more hundred extra dollars.
Only time will tell for me if it will last longer. but I truley think the OEM parts are a bad design for the YUKON product line
--------------------------------------------------------
oh and as a footnote I bought my truck used and had to replace the tranny at the 120k mark. however the previous owner was the original owner and he had to replace the tranny at the 60k mark.
good luck everyone

I see that you are experiencing some difficulty with your transmission. Have you already had this looked into by your dealership? I would like to see how we could be of assistance in addressing your concern.

I just wanted to put my two cents in this thread. I have 2003 yukon 4x4. transmission made whining noise last night. This morning it wont go into reverse. I purchased 2 new GM products at the dealership within the last 12 years this yukon being one of them. I like the yukon.. problem is that they are inferior products. I should not have to worry about a transmission at 149k miles. I already replaced the water pump, rear axels, unit that controls the shifting into 4 wheel drive. So disappointing. Of coarse after searching the internet "The sudden loss of reverse in a 4L60E or a T-700R4 is a common problem in respect to the actual amount of internal problems these transmission have" NICE!
What a shame that the transmission only lasted 66K miles. I have loved the car until now. A high end SUV like this should last longer. Should have been a red flag to see a 36K warranty. My local GMC dealer has ripped me off on previous repairs, when they mis-diagnosed a loose oil filter. So, unfortunately, can't take it to them. I'll review Consumer reports very carefully on my next purchase.
As I am a very conscientious driver and prefer to drive my vehicles quite gently in hopes of prolonging their longevity. Apparently though according to what I have learned through researching the subject, their appears to be a history of failures regarding the 4L60E transmission. Following the conversations with the albeit few repair shops that I was able to contact whilst out of town, each one of the reputable repair shops seemed to know exactly what was wrong with my Yukon tranny. They all stated that I was going to need a transmission replacement. The estimates given were in the $1,000 to $3,500. OMG! Why would this happen to a vehicle with just 80k mile on it I kept repeating…
So, after spending hundreds of dollars to have it towed back to my hometown, I am now faced with the dilemma regarding the estimated costs to repair it. Like most working people in this country, I can’t work without a vehicle. What I have since learned about the ‘well known failure’ occurrence of this transmission from researching the TSB’s and documented cases, it has been an ongoing problem for quite some time. I desperately need the customer service reps at GMC to step up to the plate and help me out in assisting in this immediate repair.
Asked them to do repurchase or a warranty extension, but I just wanted it fixed....
