Changing the Transferbox oil - 4/23/2008 11:10:45 AM    Captain Ducman Posts: 15 Joined: 11/5/2006 Status: offline Ok, I am most of the way through the 60k mile service and was wondering if anyone had done this and had some "Been the Done that" advise.  My truck is on the lift, we've completed the plugs/wires, the engine flush, oil and filter change, front and rear difs, when my helper had to go back to work.  I am supposed to go back to the shop in a couple of hours to help complete the servicing. Thanks in advance, Steve Post #: 1

If you've got a LIFT it should make life alot easier.  Typically there is not a drain plug for differentials and transfer cases rather a fill.  You're limited to either vacuum pumping the fluid out or siphoning.  Obviously the bigger the hose the better.  I've changed out the fluid on rear-ends before using the typical fish-tank air-hose crap and it's painful...but doable. Keep sucking the old out until you are reasonably satisfied that you've gotten it all, then refill with new. I would be interested in seeing what others responses are though.

That's a sweet gig!  Most differentials I've worked on only have the fill!  If someone tells me that the transmission has a drain plug I may be in heaven. not to hijack this thread but is 80/90W synthetic gear oil the recommended stuff for the transfer case and both diffs? < Message edited by unstable -- 4/23/2008 1:06:30 PM > (in reply to llesra) Post #: 5

D1's have fill tubes for the tranny while D2's don't, need to ddain then fill them thru the fill plug on the side of the tranny pan. _____________________________ Mike Retired service manager.

Thank you all!! The lift makes this a much easier job to tackle, I used a $6 hand pump from Advance Auto Parts. Drain and fill ports for both difs, xfer case, and transmission makes this a very easy job. I spent about $160 in synthetic fluids and sea foam but it sure beats whatever the dealer would've charged me, plus I got to see first hand the magnetic drain plugs and the condition of the life blood coming out of each component. We went so far as to run each fluid through paint strainers to look for possible problems. The biggest thing we found were some thin short shavings from the transfer box and they were trapped on the drain plug, nothing in the fluid. In return I have the peace of mind knowing this has been done and there is no excessive wear going on. Again thanks to all who have posted on PM of their rovers, Steve (in reply to Disco Mike) Post #: 7

RE: Changing the Transferbox oil - 4/24/2008 5:28:12 AM    unstable   Posts: 166 Joined: 4/20/2008 Status: offline Thanks for your post bruv.  I'm working toward the 60K checkup on my wifes rig too.  We've only had it since Saturday and I've already put new brake pads all the way around and did the first flush and oil change. Tonight I'm hoping to rip the front driveshaft out and go get that rebuilt.  I need to find out how to engage the CDL so the rig is still driveable. I'll have to check the account for $$$ but maybe this weekend I'll embark on draining the diffs and doing the tranny service. EDIT-->Pertaining to the Discovery II transmission fill plug...I guess that's better than a transmission with just a dipstick and no drain or fill plug.  I absolutely HATE doing tranny services on rigs where you've got to unbolt the pan and splash ATF all over yourself.  Even when I've managed to do this right, I always get covered in ATF. < Message edited by unstable -- 4/24/2008 5:30:07 AM > (in reply to Captain Ducman) Post #: 8
