Thread: LSX-90 in transfer case

I had our 05 fender in for it's second yearly service yesterday. Despite me supplying syntrax for the transfer case, it would appear that they have put LSX-90 that I intended for the diffs in.

Will this be ok? I presume they wouldn't have done it if they were worried about it, but is it optimal?

Tech info states for the Defender T/case 75w/90r for most temp ranges.

For LT230T in Discovery 75/85 through to 90ep can be used.

P38 transfer - ATF

LT95 - engine oil.

B/warner transfer - ATF

I cant see why syntrans or similar 75/85 or Castrol Transmax cant be used. I use the Castrol version in the LT230 and R380 with a turbo Isuzu driving it and have had no problems with them.

If you were using the vehicle in very hot conditions and towing I would assume the 90ep would be the go in the defender.
