Will trans fluid pass thru from trans to transfer case?
Or do I fill transfer case?

trans and t-case are separate. the t-case has a drain and fill plug on the back of it. it'll be either a large hex or a inside square.

Thanks,  Just had to ask because there's a gasket between them.

lol you can fill through the tranny if you somehow have broken that seal.....and then ur 4wd wont work after you drive 3 hours not knowing it was broken....lol bad experience
