I switched from Mitsu gear oil, what ever they use, to redline 75w-90 gear oil in the tranny, transfer, and rear end for my 94 VR-4. It is does fine when it warms up. But I thought this stuff said it would give you easier shifting when it was cold. It is right around freezing where I live in the mornings now. Even just before it got cold here it was still a little harder to shift once I switched. I like being able to feel it go into gear but not at the expence of harder slower shifting. What's the deal? This stuff was expenceive for me and I have to say I am dissapointed.
