I just drained my trans pan twice of three year old Amsoil as it was hit. Filled it twice (5qts x 2) with CAM2 ATF to get me by till I flush and re-fill with Amsoil next week. But as i went through the gears to re-fill the clutch packs and check the level I notice that it would always torque the truck WAY more in drive than in first or second. Any thoughts on this since the trans should be getting 30% or more line pressure when manually shifted. Has the Diablo Sport-Predator set on the 85HP tune FYI.
