Motul MOTYLGEAR 75W90 - TechnosyntheseŽ - API GL-4 / GL-5
We have used it successfully for about 6 years and everyone we have supplied has found an improvement is shift quality on both 901 and 915 transmissions.
When used with a plate type LSD it does need a small amount of friction modifier.
I used the Redline 75/90NS and also found it good but when we switched to the MOTUL we did see a shift improvement.
I would never use Swepco in a 901.
