The Dragon is right. Sorry, I never considered the tyranny having motor oil in it. But, from the pic I thought it was for sure from the tranny but listen to him. I always do.no telling what type oil you have in the tranny..it may be gear oil,it may be automatic transmission fluid or it may be motor oil.there are different opinions on what to use in these newer manual trannys so no telling what has been put in it...if it is coming out of the transmission and is dripping out of the bell housing then the tranny will have to be pulled in order to replace the front seal in it
I was told gear oil to put in the transfer case?You definitely should not have ATF. It should be either Gear or Motor oil. ATF goes in the TC. If someone took out the correct oil and replaced it with ATF that could be the cause of the problem. Either way it is an easy fix. There is a bearing retainer plate held on by about 10 bolts that the input shaft goes through. Remove that and the seal is right there. Would be wise to look at the clutch while your in there too.
x2No matter where it is coming from (according to the picture) the transmission is going to have to come out.While it is out Replace the rear main oil seal (easy) and put a front seal in the tranny.It would also be a great time to inspect the clutch,pressure plate throwout bearing and pilot bearing.
