Ever had this isssue? Tought I was loosing fluid out the t-case rear output shaft. Changed the rear output shaft seal helped but no go. When I looked again looks like atf from the bell housing in front. Talked with the guys who put my new south bend in and they are thinking the front input seal on the trans. Clutch went in 5 months ago. They want $850.00 labor to pull it out and look. What the ****. The clutch only cost me $450 in labor. Anyone had fluid leak from the front or replaced a front seal in the trans. I will do this one myself (for free)
