Replace Gearbox,Transfer Case and Rear Diff Oils. T30 5sp 2002
Gday all, Just thought id take a few pics when I changed out the drivetrain oils.
This is quite simple to do and will save you some dollars if your exy is out of Service Schedule. This procedure is for a 2002 T30 5sp but it would be similar for most models.
Alright here goes.
- Whip down to your Local Auto parts store and get yourself the following.
- Manual gearbox Oil (I used Castrol VMX-80) Could only find in 4lts. Approx $42.00
- Transfer case and Rear Diff oil (Castrol EPX 80w-90) 1ltr bottle. Approx $13.00
- 'Tom Thumb' hand pump. Approx $23.00 This is a good quality pump.
- Long plastic thin funnel $3-4
Dumpster dive your Recycle bin and find some plastic milk bottles for when you drop the oils down. (two milk containers fro the diffs but maybe find something a bit bigger for the gbox as about 2.2ltrs will come out )
- Locate the 10mm Hex key plug on top of the gearbox and remove.
The filler hole is next to my thumb (Its easier with a long extension bar and breaker bar)
(Note) - Always remove the Filler plugs first when doing these kind of jobs because if you remove the drain plug first and then manage to strip the filler plugs thread, you will have to call a tow truck as you cant get oil back in it
- climb up under the gearbox and locate the 10mm hex drain plug, remove it slowly and catch oil in container
- Let it drain for a while (Good time to remove the filler and drain plugs on the transfer and rear diff)
- When drained put the drain plug back in and tighten.
- Place long funnel into fill hole and pour you 2.2lts slowly in.
- Tighten nut and your done.
- Transfer Case
- Assuming oil is drained, replace the drain plug back in with some Silicon Goo on the thread.
(Top hole is filler - taken from underneath car looking up)
- Take your 'Tom thumb' pump and fill it with 0.5lts of oil and place the tubing into the filler hole (easier to get to with Drivers wheel removed and sliding in over the axle)
- Pump til oil starts to come out of the filling hole, do this slowly so you dont create air bubbles and a false level. about three minutes to fill.
- Replace 12mm nut with silicon goo and tighten, your done.
- Rear Diff
- Climb up under rear of car and replace you 10mm drain plug.
- Fill your hand pump back up with another 0.52 ltrs of oil again and place tubing in fill hole
- Slowly pump oil in again til it dribbles out, Replace Fill hole and yep. done.
- Overall the oils weren't too bad and were prob replaced before I took ownership. gearbox was pretty black tho.

Re:
Yes they do otherwise they can't send drive to the rear wheels.
Just look where the prop shaft joins the transfer case.
The transfer case is bolted to the transaxle where the front drive shafts come out from which is bolted to the engine.

Re: Replace Gearbox,Transfer Case and Rear Diff Oils. T30 5sp 2002
I just wanted to say Cheers! to Scott, for his ridiculously well described engine rebuild and oil replacements posts, and thank God that I made the effort to actually check (and subsequently replace) them myself, even after having a major service done only a few weeks ago. I figured I'd also check the engine oil too, while I was at it. And, well, I'm sure the photos can speak for themselves..
5L's of this was in my engine!
And I'm sure the little filter was still efficiently doing it's job..
And of course, the rather proud moment I had (one week later), upon checking the engine oil and grinning at the comparison. Thanks again, Scott!
(Apologies for the unclear photo, but it doesn't take a rocket scientist to identify that nice synthetic colour vs. the previous jet black =D )
I am also quite relieved to add that my diff, transfer case and gearbox oil were all positively beautiful! (not sure if that's exactly a fitting descriptor when talking about motor oils.. but hey, the car is 10+yrs old after all!) I probably should've taken a photo of all the healthy-looking oils in their tubs and catch trays before I filtered it all back in, haha. I will attempt to remember this for future edneavours.
