Did some trans service today change oil and increased linepressure from 65psi to 80 psi because the truck was shifting to soft, took a testdrive but it didn't help.
How do i get it to shift harder?
I'm post a pics of the oil, it's 10000 miles since last change.
I use atf 3 and a bottle of Red Lube, DTT tech told me that.
Could there be any issue with the clutches?

 

Use ATF+4, it is the specified fluid required. No snake oil additives required. Get a break on price at Wally World.
The color of fluid indicates was time for fluid change.

 

Increased the line pressur today to 88 psi, now i really notice that my tranny pulls and shift distinct. Just as i want! When i got my suncoast vb the pressure was 75psi.
