My wife and I have just purchanced our 1st american vehicle(coming from a line if bmws)a 2008 Cadillac Escalade and its fantastic. We love the space and the ride is absolutely wonderful. This weekend driving it I noticed a clunk in the transmission as it down shifts from 2nd to 1st. It also clunks when I put it into gear from park or any sort of gear selection. After hearing this I went and did a transmission fluid change as the vehicle has just under 80k this did not help much. Driving thru the gears its still smooth and no noises at all. I'm a little worried as I just picked the vehicle up last week and a transmission repair is definatley not on the agenda. Is this normal noise in a GM or signs of bad things to come.

Hello Crijan11,

Welcome to the Cadillac family! I am glad to hear you and your wife are enjoying the space and ride of the Escalade :) I am sorry you are experiencing a clunking noise. Have you thought about taking the vehicle back to the dealership for a possible diagnosis?

I called in today to tell the sales rep that sold us the vehicle and he said he never heard the car make any sound like that. He claimed he drove the car on my occasions for personnel use. The dealership is about 2 hours away so if I can avoid a trip up I would but I definatley have a option to go back if need be. He said that gms are usually noise when selecting gears, I don't know maybe I'm used to our x5 it was pretty quiet. I've read on other forums about flashing the transmission or even maybe a motor mount being broken can cause a sorts of clunks or thuds??

My ext does on the the way up 2 to 3, I took it to the dealer a couple months back and nothing was found. I started using my ext as my daily driver and found a sweet spot in the RPMs to get rid of the clunk or hop. It seems like it happens less and less everyday.

It's the transfer case. I have had to put 2 in my Escalade. I also have 235,000 miles. The transmissions are bullet proof according to a few trans shops in my area. There is absolutely positively no doubt that it is the transfer case. A rebuilt case with a 3 year warrant cost me $1300 from a company called LKQ, they are out of North Jersey. That price is just for the part. I'd say installed you are looking between $2000-$2500.

I also have a 08 esky and I have the exact same problem it drives me nuts to the point I was going to sell the car it takes all the pleasure of driving away. And I refuse to pay 5 grand for two transfer cases I have only had the car for less than 3 months

I now have 115000km on the odometer I got it with 107000km

I thought this was caused by a broken motor mount?? I've noticed mine does it once an a while, really disappointing for a truck that is so expensive new.. maybe that's why the depreciate so fast

Oh man that's not the answers I was hoping to hear. Thats a little dissapointing on Cadillac behalf, having these kinda of issues before 150k. The should have spent some more time at the drawing board. I'm going to contact the dealer I bought it from, I'm not dealing with this kinda headache already.

This seems to be a problem a ton of escalade owners have had they have a TSB out that could not describe the problem that we are having anymore clearer TSB #09-07-30-004B it looks like some fluid seal rings need to be changed ... problem im having now is because the truck isn't showing an error code they said everything is ok clearley it is not what can we do?

Welcome to the forum. I have had 12 Escalade's, what you are hearing/feeling is not normal. How many miles? Did you have it checked by a pro before your purchase? Did you buy it from a dealer?

Hello Crijan11,

I apologize it is an inconvenience to take your vehicle into the dealership since they are 2 hours away from you, but I’m happy to hear that they are going to take a look at it. Did you get a chance to take your vehicle in today? What did the dealership say about the noise? Thank you for keeping us updated on the situation. We will be looking for your future updates as well.

Idid go in today and what he told was that this is a fairly common thing amongst escalades and he thinks that our first step be to take it into the dealer and get the tranny flashed or some sort of update that can be don't so I will try that early next week. In the mean time I'm going to get all the fluids changed in the diffs and transfer cases and see if that also helps.I think I'm do for that kind of maintenance any how.

Well Cadillac EXT seem to have this problem and my 2007 has always had this, my truck has 132K on now and still has this. I have always waited for a big Bang and this would be it, but never happened. I even tried driving a new pick-up off the lot and still felt it.
Well a couple of months ago we bought a 30' travel trailer and I took truck into a corner garage and had all fluids changed . The difference in shifting and clunking noise is very minimal now that I hardly feel it and have put on 3K since change over. The treatment was BG oil!! Yes the cost was $625.00 and well worth it!! This proves that you can buy a luxury vehicle and the manufacture uses low grade fluids just to get it out of the door.

I am really pleased with product!
Now looking up replacing front rotors and pads for towing

Soo today I had the car in at the cadillac dealership and had a diagnostic done on the transmission. There are no codes no errors or glitches with it. They test drive the vehicle and said that it was only occasional that they heard it and that it was very minor. They stated that because of the 6 speed transmission and being awd is the reason I could be possibly hearing "some" noise. So long story short no issue. I'm confused either I have a good sence of hearing or the tech is partially deaf. I ended up changing all the fluids in the diffs and transfer cases and it didn't do anything to help the clunking. I am planning to follow up with the dealership as I did see a note that said possible transmission program update. Has anybody had this update done? What where the results after

Our 2008 esv awd had a very similar sounding issue. Th transmission got reprogrammed, serviced, etc. none of that fixed it.

It was a broken motor mount.

Check your ujoints

Motor mount is very easy to diagnose in your driveway. It takes two people : first person depresses brake firmly and puts escalade in gear. Keeping brake firmly depressed, first person presses throttle gently. Second person watches the engine where it attaches to motor mount (from the driver side of the truck, not the front!). If the mount is broken the engine will raise off the mount. To check passenger side mount, repeat process while trans in reverse.

Check your ujoints

I had the exact same issue a year or so ago and it was the u joints in my case. They replaced some parts and the shifting was smooth as silk. It seems to have come back though as I am starting to feel/hear that again... whoops! Hope that's not the case.

Our "clunk" appeared after the first start of the day (cold temps), transitioning from reverse to drive out of the driveway. There was an excessive delay in the time to transition from Reverse to Drive (sitting in street for a good 2-ish seconds for it to clunk into drive). Brought into dealership we bought from and they said there was no problem (of course) because they couldn't duplicate it. Fast forward a year later, still clunking, took it in for some 60K-miles service items and they investigated a clunking sound. Turns out it was (supposedly) a broken driver's side engine mount. Extended warranty covered the cost... they claimed it to be about a $700 fix, but the $50 deductible is what we ended up paying. Anyway, time will tell if that was truly the cause, but sounds plausible.

Thank you for following up Greg. Really appreciate it. I am not really bothered by it at this point so I think I may just leave it, unless it get worse. I will pay more attention to it though.

I have the same clunk in my Escalade. I have owned a GMC truck for quite a few years and had the same "type" clunk in my Sierra. I was told by a tranny shop that is was the extra play in the yolk/shaft that slides in and out of the tranny. He filled the space with grease and solved the issue. The space or slop is there to allow the extra movement when the wheels travel up or down clearing bumps, it shows up when the power is quickly transferred to the wheels as when you shift into drive or sometimes between gears. The dealer will likely find nothing wrong. It is annoying, but pretty harmless if it is the same issue I had, he actually brought me in and showed me the "play" in the drive shaft to tranny while the truck was still up on the rack.

After official giving up with the local cadillac dealer I took it to a transmission and drive train specialist. Turned out it was play in the shafts due to the u joints. Replaced them for $200 . Drives like a beauty and is silent. The reason for play occurring is not engaging the emergency brake when parked on slopes. We all notice the car bounce back and forth when we park:) all the weight is eventually going to wear those joints out.
