MTF Comparisons?

I have the OD Was running 80w90, then 50/50 with dexron/ then 75w140/ never could get 3rd gear crunch to go away. 1st gear was hard to get into at times. So finally after a year of this BS, I decided to fill it with Valvoline synchromesh. wow the 3rd gear crunch is gone. Never shifted better. Have 5 miles on it and it is super smooth. Time will tell. The unit is going to be replaced. But it works good enough for now.
