Re: Correct Trans and diff fluid for a YJ
 

Mike,

I find your description of my assitance to this guy offensive and
uncharacteristic of you. What I stated is fact. The AX15 can not tolerate
80w-90 GL5 gear oil. DC recommends a special GL3 (no sulphur) oil available
from Jeep dealers. They also make a special GL3 oil for the NV3550, which
has the same issue re: GL5 oils.

If he uses any form of GL5 gear oil he will experience difficult to
impossible shifting (esp. in extreme cold) and substantial gear clash. Sorry
if my reply offended you, it's just the facts.

Sorry if I got mouthy.

The GL rating has nothing to do with the weight of 80W90.

Re: Correct Trans and diff fluid for a YJ
 

Mike,

The original manuals called for a 75w-90 GL5 oil and were corrected by tech
service bulletin years ago. Any 80w-90, even if a lower sulphur GL4, is far
too heavy a lubricant for an AX15 or NV3550. I believe Redline MTL is a
70w-80 GL4.

Re: Correct Trans and diff fluid for a YJ
 

Mike,

The original manuals called for a 75w-90 GL5 oil and were corrected by tech
service bulletin years ago. Any 80w-90, even if a lower sulphur GL4, is far
too heavy a lubricant for an AX15 or NV3550. I believe Redline MTL is a
70w-80 GL4.

Re: Correct Trans and diff fluid for a YJ
 

It calls for a 75W-90 GL-3, and there were some years when the shop manuals
incorrectly called for a 75W-90 GL-5. Redline's MT-90 is a 75W-90 GL-4, MTL
is 70W-80 GL-4. If you go with Redline, MT-90 is the correct viscosity.
