Hi all, this is my first time having to deal with a situation like this so I am after as much advice as possible.


My car was due a service last week so I picked a well respected specialist garage to do the transmission fluid change as this was a part that I didn't want to get involved in. Too many awkward filler plugs to be messing around with on my garage. I am a capable hobby mechanic and have maintained my own cars for many years.


The transmission fluids were all changed and I drove the car 50 miles home down the motorway. Once home I carried out the engine service with the new oils, filters and plugs. 3 days later I come to drive the car and there is a constant transmission grind/whine whilst in motion. There is a video on youtube titled "Strange evo transmission noise"


I've spoken with the garage and they want the car back to investigate as they can't diagnose from the video. So in the new year I will have the car taken there on a truck as there is no way I'm risking driving it.


I don't know how these situations normally play out or get resolved. All I know is the car was perfect when I took it there and now its broken. Is this a clear cut case?


Many thanks in advance.

Not really. Pre existing faults can be getting worse with no external signs. It takes the strange noise or different 'feel' to alert tbe driver not all is well. Exchanging fluids will not be seen as a contributing factor UNLESS an incorrectly specified fluid has been used. Was what they charged for, what you actually got?


They ma need to strip down the shaft to identify the problem (hopefully they will discount he cost of doing this) but remember this was not done he first time, so they cannot be liable to fix something they never saw originally until the disassembly. So take it as it comes, and keep full notes of what happened and when, and record any telephone calls in case a dispute arises later.

Thanks. I fear it's not going to be as straight forward as I hoped. I'm absolutely furious that my conscious decision to have a professional do the work has resulted in a problem. Fact of the matter is that only 1 person has touched the transmission. Maybe I am looking at it from a biased point of view but to me all fingers would point in the same direction.

I've listened to the noise on the video and it's quite clear that it's a bearing failure however where is not clear as you did not change gear. However it seemed to be linked to road speed so would suggest that the car has been run without oil in one of the diffs. I'm not totally clued up with the 4 wheel drive set up on your car and whether or not it has a transfer box or not. I would also suggest that the car has been run without oil in the affected area as even with the wrong oil it would not fail in such a short space of time. The mileage also suggests this as you would have heard this noise very early on if the bearing had been suspect. An expensive mistake for the garage to make me thinks. You need to be present at the initial investigation drain down to verify if any oil is there and to take a sample if need be.

I do a few gear changes in the video. I accelerate through the gears and also shift from 5th to 4th and back while at constant speed - note the tacho movement vs speedo.


There is a transfer box on the car, its permanent 4wd with an active diff to adjust the power to the wheels.


I too think that the failure is too quick for wrong oil viscosity. It's going back to the garage on the 4th jan. Hopefully it will get there at a reasonable time so I can see the start of the investigation.
