I am leaking a small amount of transmission fluid from where my drive shaft goes into the back of the transmission. Its just a little bit, like 3 drops in past 12 hours but there is more around that area that hasn't fallen yet. What is going on? Should I be concerned?

 

Tail shaft/output shaft seal leaking. Very, Very, Very, Very, Very, Very, Very, Very, Very, Very, Very common from about 99 on up. Did I mention its very common? You might jiggle the yoke and see if there is any play in the bushing, usually there is. On the ones that aren't leaking I've jiggled the yoke just to see and they all have IMO a lot of slop yet some leak and some don't. You have to pull the driveshaft out but its about a 20 minute job to change it out. It just drives in.

 

Rear seal. If so, driveshaft needs to come off. Pop out old 1, replace new. Install shaft. But mine has done this for some time. I figured the trans would be removed by now, so i didn't dink w/ it.

 

+1 one on what they said!
