Transmission Leak

Recommended Posts

I got the sudden urge to creep underneath the truck earlier, and discovered an oil leak at the end of the transmission where the driveline connects. There's a gasket there and that's where the oil is leaking from. There's a drip there, I don't even wanna know how much fluid I've already lost just from driving it. Luckily I caught it in time and know it's there now. Anybody know what I'm talkin about? How hard of a fix is this?

That would be the end of the Transfercase. There is just a seal there that the slip yoke of the driveshaft slips into. You will not loose enough oil from that seal to hurt anything. The oil drain and fill plugs are on the left side on the back and are allen head plugs requireing allen wrenches to remove. just remove the top one and top it off. the t-case only holds 3.5 quarts of ATF. Or just change the fluid. You can replace the seal but generally unless you take the t-case apart and replace the output shaft bushing it will always have just a drip hanging from it. Don't worry about it unless it starts leaving puddles. I have replaced many many of these and they always have a drip of oil hanfing off it no matter what.

Thank you very much!

It couldn't have been there for very long, there's no residual or dry oil around it. Looks like it's a few days fresh.

As for the fix, Does it require a tear down of the transfer case for the seal?

--- Update to the previous post...

oh, nevermind.

I have same thing. After what W&F on previous post said I just monitor it to make sure I don't get a bigger leak and fill up with fluid a bit more regularly (Like 1x in 1 year).

To replace the seal just requires removal of driveshaft only then pry the seal out and gently pound the new one in, simple as that. Seals are only around 15-20 bucks so it won't hurt to replace it, not saying it isn't bad as they do dry out and get hard over time.

to replace the bushing should only require the removal of the tailshaft correct? then you can just tap out the old bushing
