Here is the info from Ashton

Just like the B13/B14/B15/P10/P11 transmissions, the manufacturer calls for a 75w90 gear oil. I believe they call for GL-4 oil as well. For those putting heavy use or above 500whp on their cars I highly recommend using Valvoline 85w140 Conventional or Durablend in the trans except for winters in cold areas. Stick to a 75w90 Synthetic. The thicker gear oil is great in this trans. When warmed up it shifts buttery smooth and it will help prolong the life of the gears and bearings and allow it to take more abuse just like it worked in the B13 trans I ran before. I will leave your choice of oil up to you. That is just my recommendation. Coheed first used it as well and liked it but when it started to cool down some it made startups and the first few blocks annoying as its very very thick. Also didn't like the feel of the shifts when the oil was cold so he went with a 75w90 oil for the cold months and no issues.

Are you guys buying your 4.7 FD direct from M Factory or from Mazworx and at what cost are you getting them?

Direct from M Factory!!

The FD wont brake that easy no matter what oil you use its because of worn bearings and flex of the shaft and the abuse at high power level that they will break!!

Yep, 85w140 Valvoline Durablend is what Ive been running. Zero issues. It works, me and several others have proved this. Works better than any other oil out there that people commonly use in our transmissions, including Redline Shockproof and so on.

I usually just pour it into a bottle and use a hand pump to pump it into the trans. Still takes a while but its faster than trying to pour it in thats for sure.
