A855 - 5 Speed

They agree with the MT90.

From post #2:

Paperwork with trans states to use 75W140 rated for limited slip differentials, but for some reason, not knowing much, it didn't make sense. Called Passon, a change was made, use:

• Part#: RED-50304
• Item: MT-90 75W90 GL-4

WOW. I just read that sheet and flipped my beenie. How does engine torque matter in break in time, and what the hell is in there that needs to “seat” together or break in? They syncro needs to grab the cone on the gear and slow it down so the slider can engage the clutching teeth on the gear.

It’s funny that they called out for a gear oil that has the limited slip component to it. That would make the syncros more grabby.

I’m lost for words on this deal.

What a bummer.
