Nice to see it's back.
Has anyone used this in a Mercon V application? More specifically a 4R70?
It is in my '02 F150 right now (for about 20,000 miles).
I have done 3 drain and fills on it (I installed a drain plug on the transmission pan) using Maxlife ATF.
First time (when I installed the drain plug and changed the filter) I used Supertech Merc V.
I had 167,000 miles on the transmission (never serviced) and was having a little "thud" sometimes between 3 and OD.
After the pan drop and filter change with ~5 qts of ST Merc V, it was almost completely gone.
About 500 miles later, I did a drain and fill using the Maxlife (4 qts) and the thud was completely gone.
I have done 2 more drains (1000 miles later, then 10,000 miles) and no issues with the transmission at all.
I am actually about due for another drain and fill (I am doing it every 10,000 miles now) and have some Maxlife ATF in the garage for that.
