Transfer box oil

[Difflock]

Just checked mine whilst in the area (Changed a snapped handbrake cable     ) and it appears to be transmission fluid i.e its red and p*ss thin,is this right ?? as I was under the impression it should be EP90/80

If you've got an auto with the viscous coupling instead of a central difflock then yep, it's right.

Is this the '93 RRC, then yes it should be ATF

I've just been through this debate on another forum.  When the switch was made to the Borg Warner transfer box with viscous coupling (1988/1989), the correct LandRover recommendation was for Dexron IID ATF.  The Haynes guide still refers to the use of EP90 which is incorrect.  I'd followed the Haynes guide until I got a Land Rover workshop manual.  Luckily after 50k miles on EP90, the transfer box seems unaffected (fingers crossed)

EP90 should be used on earlier transfer boxes; ATF on the Borg Warner.  I contacted Haynes who will make a change to their information when/if they update the Rangie manual

Definately Dexron IID, thats what i am using for mine :D

Because of the afformentioined cockup I ran mine on EP90 for well over a year.  It makes no difference (tad quieter).

Thanks for that boys,I thought I had a duffer on my hands,looks like she my have been serviced by someone who knew what they where doin

P.S its a 5 speed manual,the 380 box I think
P.P.S its the BW transfer box

Now I heard something about the R380 being a different oil to DexIII, but if reverse is next to your leg then it's a R380, if it's next to 1st (and the box is s**t) then it's a Sherpa van box (LT77).

Land Rover now recommends using MTF in the R380, although ATF is fine.
