Now the car has done 90k with full history and before the change it didnt do the noise. However I had the back box changed at the same time due to ruat.
Now the noise is strange, its like a grinding grating noise. It only does it in first from what I can tell. It changes up super smooth and all gears work as they should. I was there when they checked the overfill allen bolt and they left it open till nothing came oit so its not got to much in.
What could it be?, should I be worrid as it drives ok?.
I tested it on the drive with my foot on the brakes and in D it makes the noise upto 2,000 rpm. It does not make it in N or reverse. The garage said not to worry about it as it drives ok but im worrid as it didnt used to do it.
Any ideas gang?
