Can anybody advise what to do. Had an engine oil change done and was advised there is a leak. Car has autoguard platinum warranty. Any advice what to do. Noticed a small juddering when coming to a stop. Transfer case fluid already changed 2/3 months ago

Could be just some oil that got onto components while servicing the transfer box. With operational heat, it has seeped down.

If you have judder, though, then that needs to be checked out. Who performed the oil service on transfer box and was it issue free before?

That black part where the oil is, is that the output shaft

Transfer case had oil change already 3 months ago and there was no leaks. Only recently like a few weeks ago had the guibo changed. Straight away the car drove better for a week but since i noticed the leak theres a faint judder coming from the transfer case

The black part where the oil is, is a transmission mount bearing set. I don't know if it is a hydraulic bushing, but if it isn't then that grease/oil doesn't come from that. Failed transmission mounts can of course cause NVH issues, but I dont know if they are hydraulic or not. I would have it cleaned up with brake cleaner and codes read from the vehicle. Then reinspect in a week.

Again, who serviced the car? Was it the dealer, very competent idie or some cheap hack working at a jiffy lube?

Hi just checked on realoem and yes that is from the transmission bearing. I thought its from transfer case becuase car has been sweet after service. And it feels like a transfer case judder but also i noticed car feels slugish on low speeds. All of the oils have been changed just never done transmission fluid yet. All fluid changes was done locally indie
