I have been reading quite extensively on the operation of the NAG1 transmission on the valve body function and solenoids and valves, and I am starting to grasp a bit where some adjustments can be made, but need some help before I go on my way and possibly explode my transmission.
What are the two fill phases, pre shift and then fill phase 1 or in the details called fill phase 3?
I get pre shift fill, overlap, and torque phases but not sure on the second fill phase. Is this the time to pressurize the brake clutch after the drive clutch is pressurized?
