I'm looking to change all the fluids on my '01 drivetrain.

DCX calls for ATF+4 for the Xfer case oil.
Can't find this stuff at any auto parts store.
Is it only available at the $$$ dealer?

What did the '98 models use in their Xfer cases? (same xfer case, right?)

 

Don't know why the +3 wouldn't work. My book calls for +2, but +3 wasn't used yet.

 

I used Dexron III in both of my trucks per the owners manuals.
See if this link helps you.


Transfer case specifications

Also I had good luck with this trick.

T- case drain trick

Hope this helps.

 

In a transfer case, I think most any ATF will work. There's no clutches, shifting etc.

That said...Redline C+ meets +4 specs per Redline. That's what's goiing in mine. I get it for < $7 per qt.

 

i went to my dealer for the +4 and it was only $16/gallon. i was happy. changed the tranny fluid and filter. didnt feel it was worth the headache to put in the wrong stuff.
