Default Changing The Transfer Case Fluid...

so i think its about time i change the transfer case fluid on my 2004 v6, what is the recommended interval we should change it at? i cant quite remember the last time but its probably been awhile since the last major service.

the other thing is i have full budbuilts on and havent dont it myself since having them on. what is everyone experience with changing the transfer case fluid and having bud builts in the way? is there anyway to change it with out having to take them off? it appears i can access both drain plug and filler plug easily but the question is removing the oil without spilling all over the skid.


last question - is there any special procedure to filling? like heating or something like that?


gracias!

theres 2 bolts on the back side of it... unbolt the lowest one to drain.... rebolt, unbolt top one, and fill. I think I used synth 80/90. You could stop by and we can bang it out quick.

Open the fill plug too when you drain, it will flow easier. You'll have to remove the transfer skid to drain.

Transfer case fluid lasts a long time. It is always the cleanest of the driveline fluid. The rear diff seems to take the most beating on the fluid by far.

Use a good syn, I think Toyota recommends 75W90. Need to double check. At any rate it will go a long time on a change.

Remove the top plug. Then pull bottom plug. Drain. Put back bottom. Then just fill the top like a diff. Better if it is warm, but I don't think it is a deal breaker. Skids are the hardest part to deal with.

Pretty much just a diff in the middle of the truck.

The xfer case drain is right over the Bud Build cross-member. You have to remove the xfer case skid to do the change. I put some tin foil over the x-member to channel the draining fluid into my catch pan.

Regardless of the state of the fluid, I change all 3 diffs at the same time anywhere from 20-30k miles.

Remember to remove the Filler Plug FIRST because you don't want to drain out the oil and THEN realize that you can't remove the Filler Plug & be stuck.

The idea behind removing the filler plug first is because it is a air inlet so once you remove the drain plug the oil will flow out in a even manner and not: "glug glug glug"


The filler plug won't be stuck all of a sudden because you removed the drain plug first

I think what KC meant was some people have had issues removing the fill plugs (so you're stuck with and empty t-case) but that's mostly an issue with the front diff since it's an allen bolt.

plugs where tight on mine had to use much force ended up stripping and getting a replacement from the dealer. I use Redline syn whatever Toyota specs in the manual. I have stock skid so skid part was easy.

Did my service for the F/R diffs and T-case before i installed my Buds...Used Mobil 1 75-90w in all three....Glad i don't have to do it again anytime soon.

All filler and drain plugs came off without issue.

For anyone about to do the service...Don't forget to get new gaskets/crush washers for all the drain and fill plugs.

And grab yourself a low-profile drain plug for the rear diff, too!

It happened to my buddy. He was draining his rear diff and for whatever reason he took out the drain plug without even cracking the fill plug. When he went to refill the diff, the fill plug wouldn't budge.

So a word to the wise--- always make sure the fill plug isn't frozen before you remove the drain plug.

Don't think I will use it for the transfer, but I was thinking about it for the diffs though.
