Xc 90 transmission noise .

[ijpears]

I've just bought an 07 XC90 SE LUX and I've the same issues I think, noise/vibration at low speeds, up to 60 then fine. If I accelerate hard I get the same.

I wonder if I should take into a Volvo dealer see when it last had any upgrades applied. Question is how would I know?

Has anybody had this problem recently as my car is doing the same and has been back to 2 different dealers who cannot find any issue.

So I had a similar transmission/gearbox issue recently: http://www.volvoforums.org.uk/showthread.php?t=195616. I ended up getting 50% paid for by Volvo UK (because I missed 1 service).

However this did not fix the issue. I drove the car 500km back home from the dealer (long story) and after a week or 2 started hearing rattling noises. I thought it could be brakes, as I had those changed, today took the car to a local dealership (who were amazing) and told me that all the oil in the gearbox was now in the coolant system, and that the problem is actually originating in the radiator. Somehow the idiots that fixed my car thought the problem was with just the gearbox, but the source was the radiator. The silent block was broken which was causing the rattling.

I had all the issues you had with revs at 1800 rpm etc.

I am furious because they say I need at least a new radiator etc. and they will need to flush the gearbox. Maybe even replace it again!

Your problem solved

Just wanted to help all the people who have had issues with the transmission or weird vibration noises from under the car. I have an XC90 2010. I bought it 6 months ago from a dealer and took out an extended 3 year warranty ( thank god). The car had very low mileage 35,000. Been driven by an old chap to the shops and back.

Anyway about 4 months ago I noticed a weird noise when I got to 5th Gear at 2200 revs. It sounded like a weird vibration noise almost like an exhaust sound/ grating noise. Almost like the noise when you have a hole in your exhaust. My first thought was the catalytic converter going. I took it into the dealer and they said it was an engine mounting and same thing again. At same time the AWD light came up saying not working. It went back in and as the car had been sitting for a few year not doing anything the filters in the Haldex Pump had clogged up.

Finally to car in last week and they had it for a week and have diagnosed the problem as being the drive shaft dampers worn out causing the drive shaft to oscillate at certain revs or between gears. They have just fitted a new drive shaft and dampers kit and it seems to be fixed. Total cost for new prop/ drive shaft plus labour about £600. Warranty covered the lot and now the car seems really responsive. Hopefully that will be the end of it. Hope that helps

That's interesting as problem like this do get posted frequently. Just to confirm it was the prop shaft between the transfer box and rear diff?
