How often do you change your transfer case fluid?

 

There's no official interval I could find from GM...so I was curious to see when you guys "typically" do it.

 

For me, I tend to change my tcase and front/rear axle fluid around the same time - this interval is 30k miles.  If I was just cruising on the highway I would extend it, but this truck tends to get dirty often enough.

most of my rigs, as soon as i buy them i change the fluids in all the diffs, powersteering, brakes, along with engine tune up. then i do them all again every summer (doing engine oil every 3,000) or if i submerge the diffs or transfercase i will change the fluid

I hear ya...

I just had to flush my tranny b/c I submerged it (~$250 mistake)

 

After that I extended every one of my breather tubes  to as high as I could get them - http://www.gmc4x4.co...tube-extension/

I want to say the last time i checked they had to be changed every 30k miles (not sure don't quote me lol) but I always tend to forget to change the fluid in that thing Hence the reasons I'm having issues with mine as we speak  :negative:

I changed all my fluids when I purchased this truck, and have all my intervals set for when I do them. Along with the book keeping from the PO who was an older man, who changed it every 25,xxx. And all fluids were recorded as well. WHen I do my SAS I will change all my fluids again as far as tranny/transfer/diffs.

For the GMT360's (TB and Envoy) The T-case has a strict 50,000 mile interval. It also uses the Autotrac II fluid.

 

I was reading my owners manual the other day and noticed that there isn't a "normal duty" interval for the transmission. Only a severe duty interval.

 

Couldn't find anything on the T-case either. The maintence scheual only has you check the fluid level and top off at every oil change. Doesn't list a complete change.
