This is a thread to document the Oil change procedure for the P38 Borg Warner Transfer Box.

Yes I know, this is simple to some!!

But we do have a " Door Card Removal " how to so eh ;) :p:D

#1 Locate the Drain and fill Plug(s) these are a 1/2 square drive, i used a my small 1/2 inch breaker bar.

First 'orf make sure you can loosen the Filler plug!

Ideally when you remove this filler plug, a nice stream of fluid should trickle out, in my case I changed it around 2 years ago so i knew the old oil only had around 4000 miles on it and TBH it wasn't in bad nick, but i used cheap crap and wanted to get some proper stuff in there ;)

Then using a 1/2 breaker bar or wrench drain the fluid out!

Leave this for 5 minutes to drain...


Then there is the most important bits.
The Oil and Syringe, in this case i'm using Mannol Dex III, the manual specifies Dextron IID or III.
If you can find IID then i'd like to know where!!! ;)

But TBH Dex III is far superior, so use that!!

The syringe is needed for a clean fill ;)

Fill the thing up with Fresh fluid.

And pump it in, this syringe is 500mil per fill so roughly 4 1/2 syringes needed for this case!!


Remember to put the drain plug back in!!

And fill 'er up!

When it starts pishing out the fill hole you're done!!

Put the filler plug back in, don't torque the mothering fook out of it..

Just snug it up!!!

Not too bad.

But the new stuff should last a good while yet..

but with it being so easy to do i'd do it every other engine service.

Literally a 10min Job ;)
 
Handy for a RR noob like me to see where the fill/drain plugs are. This is on my list to do along with engine and gearbox oil and filters.
 
Not always about confidence, sometimes it's ability. Still nice, for those not able, to see how to . Good one @Henry_b
I'll happily take an engine out and rebuild, but ask me to take a door card off and I'll make a right mess of it
Good job there! Always a good habit to chock a wheel while you're underneath and an axle stand or 2 if you're using the suspension to lift it up for easier access
