Default Transfer box oil - Dexron11D or Dexron 111

Hi all,

I want to drain/refill the transfer box- ( 1998 P38 4.6 Auto )

Local supplier only has ATF Dexron 11 not ATF Dexron 11D as recommended in my manual. Any one know the difference ?

A search mentions Dexron 11 being replaced by Dexron 111 about 1995 - I have plenty of ATF Dexron 111 available. Anyone used the newer Dexron ?

Thanks

EP 90 for the final drive units in P38

I have read that one can go "higher" with the numbers but not lower. Dexron 111 instead of Dexron 11 but not the other way round.

Am interested to know if anyone has "changed up " and any issues that resulted

Dexron 111 equals or exceeds Dexron 11 specs. I suspect any damage from using this may show up after another 15 or more years of use. Dexron is correct for P38 transfer box. Note there are seperate level plugs in main and t/fer boxes.

The manual mentions Dexron 11 D - how does that differ from Dexron 11 ?

Dexron 3 supercedes 2 - it'll be fine...just like years ago Dot4 replaced Dot3 in brake fuid.....as already said it's ok to go Up, never down!

just ordinary aft dexton 2 is fine ,synthetic oils are dsesigned to last longer, car manufacturers are obsessed with extending service intervals ,good cheap oil as used by most in the trade changed often to remove contaminents is better than the highest priced synthetic left in a long time,although the correct viscosity can matter

My version of RAVE specifies Dexron III for what it's worth. The only thing I wouldn't do is replace III with II.

Maybe wrong, but thought you said the other day that it was not cross referencible and that Dexron III could eat oil seals. Make ya mind up.
