Synergyn substitute???
I was planning to pick up some fluid and drain/refill my T-56 today.
I want to mix 2 quarts of Mobil1 with 2 quarts of Synergyn but thats not an option.
Is the Redline 80w140 an okay option as well? Synergyn II is shown to be 80w140 as well but it's a GL6 rather than a GL5+. I'm not even honestly sure what the difference is.
I guess I just need to know if my trans will like 2 quarts of Mobil1 and 2 quarts of Redline 80w140 or Ams Oil 80w140.
Trying to find out ASAP

To answer your question , I would not use that heavy of a fluid in a T56 .
I ended up running 2 1/2 quarts of Mobil 1 ATF with 2 quarts of Mobil 1 75w140.
Noticeable difference in shifting.
I'm currently having occasional issues with reverse. I go to put it in gear and it feels like its in but it isnt and then I have to put it in again. No grinding or any other issues and 1st gear is fine.
Before reading the FAQ on here I had swapped in Royal Purple about 10k miles ago.
