One of the best if not the best companies that makes lubricants is Petro Canada. Some people may laugh but all GM, Ford and Crysler vehicles world wide use Petro Canada products in thier factory fill. Except for those vehicles requiring synthetic engine oil.

Try going to the 75W140 rather than the 75W90 that is asked for. 75W140 is considered the heavy duty lub for rear ends and transmissions. Ford changed from 75W90 to 75W140 in all the police Crown Victoria Police Interceptors to prevent rear end failures and it made a big difference.

For what its worth the last time i changed my trans a diff fluid i used Eneos 75w90 in the trans and Redline 75w90 in the diff (i had two bottles of Redline 75w90 left over from something and i was pleased with it last time so i figured i should just use it up -- no preference for it being in the diff or anything).

I changed the diff first. I have this crappy pump i use to pump oil for these types of jobs and without fail i always spill some. It gets on my hands and on the pump. With the Redline oil this was no problem at all. I just kept pumping until it was full. When i got to the trans i cleaned up the pump and started filling the trans with Eneos 75w90. Inevitably i spilled some and it got on my hands and the pump. But this time I could barely hold on to the thing. It was slipping out of my hands and the hose kept popping off the pump. Call me crazy but there is something rather slippery about Eneos for being the same weight as the Redline.

Not sure how they both react in a hot gear box but between my fingers and pretty much anything it gets on it's super slippery. Shifts feel much better than with the Redline. Because of how slippery Eneos felt to the touch i'm inclined to believe the smoother shifts were not solely attributed to the "new oil feel".

^ Eneos 75W90

says on their manufacturer website that it is okay for differentials (NON-LSD) type... we have LSD's in our RX8.. I hope you were aware of that before your choice of oil.

Also looking at the typical properties of Eneos 75W90 vs. Redline 75W90, I'd take the Redline one as being better.
