Changing the oil this weekend I noticed there was a leak where the trans and transfer case mate. It has leaked on top of the skid plate so its noticeable, but wondering has anyone else had this issue? Searched the threads to no avail. Please help.
I checked the trans fluid level - is good.
Tcase - is hard to tell.

 

The seals are probably bad. There is an input and output shaft seals. Need replace if it's leaking between the two.

 

thanks zman just found the thread in the DIY.
How tough is it to pull the tcase out? How much time would it take the mechanically inclined back yard mechanic?
Is it ok to drive like this if I do not use the 4x4?
Is this one of those common problems we are always running into?

 

R & R is about three hrs work. Keep the fluid topped up and it will last until you fix it, but oil spraying around under a truck is a mess and a hazard.

 

Having had this same problem, get it fixed. Mine was so bad I was having to add trans. fluid every 2 weeks. I had my trans and t-case serviced at the same time. Cost me $302 for the whole she-bang at a local trans shop.

 

t-case is easy to remove and not that heavy. sheriff has a thread on it. pop off linkage, vac line. front drive shaft. 4 or 5 nuts at transmission. get your knee up under it and press it down.

how do you know which is leaking? trans or tcase?

 

Having the same issues with my 98 1500. I'm taking it to a friend later this week to get the seal redone. He said that it would be a 3-4 hour process if I did it by myself.

 

thanks all
dvaughn - i think it is the trans simply because I recently completed the trans service, but have royal purple in the t-case. The leaking fluid is blood red. I simply looked at it said *&#% and finished the oil change.

 

is there any risk of cross contamination of the fluids? should I change both?

do I need to drain just the tcase? or both?

 

Two things, put ATF4 in both, that way you have less fluids to buy and no, there isn't a real risk of contamination between the two.
