It’s interesting Pawel that such a minor deviation from true in one component caused vibrations. Given that, it’s surprising that most drivelines run smoothly. I guess something like that may not be apparent on a GoPro camera either.
It sounds like an issue for the workshop who did the swap Christian (or did you do it yourself?)
Thanks a lot for your input, and I have indeed an appointment the coming Monday with the workshop, who did the Getrag 5-speed installation. They will raise it on the lift and take a look what is causing the vibrations.
I will keep you posted, once I have news from the workshop. :-)
By the way, about the Getrag, then it is running smoothly in all gears (except reverse where I sometimes have to work it a bit in and out to avoid "teeth brushing" and make it engage) with ATF Dextron III, although with a slight bit of gearbox noise, also when warm at certain rpm levels.
In connection with the visit to the workshop, I will therefore also ask them to change the ATF again in the gearbox, as the gearbox had an unknown past history and was a bit of a gamble to install, and after 1300 km it may be good to flush the oil out and refresh with new oil. But I have also asked them to add some engine/gearbox add-on, which I have with succes used before in the engine oil in my other cars, and which reduces the internal friction between contact surfaces. It is not a Teflon based product, but it chemically works with the internal contact surfaces and makes them smoother. I am thinking that this may cure some of the slight noises, the gearbox makes and will extend the lifetime of the gearbox.
What are your views on this?
Cheers,
Christian
