Transfer case Y62

Hi guys . Has anyone done an oil change on their transfer case .? If so what fluid did you use and did you have any problems doing the job.

There appears to be problems finding an equivalent product to ATX90A. Castrol claim their equivalent is SAF XJ which seems to be a synchromax 75-140 equivalent.

Does anyone have any of info on this topic or do you just pay the stealership the money and say thank you but you are f...ing dear.

Cheers Ian

apparently this stuff is compatible with 13-22 model Y62 transfer cases
