Notes
Inspect the shift solenoid valve C function with the HDS.
Check for a seized shift solenoid valve, and inspect the O-rings.
Inspect the line pressure solenoid valve A function with the HDS.
Check for a seized line pressure solenoid valve A, and inspect the O-rings.
Check the ATF level. If the level is below the lower level, check the ATF cooler lines for leaks and loose connections. If necessary, clean the ATF cooler lines.
Check the ATF level. If the level is above the upper level, drain the ATF if it is over-filled.
Check the ATF temperature sensor O-ring for wear and damage.
Check the main regulator valve in the regulator valve body for free movement, and check the valve springs for wear and damage.
Check for a clogged orifice in the separator plate. If the orifice is clogged, remove it and clean the separator plate orifice.
Check the lubrication regulator valve, the lubrication shift valve, and the lock-up shift valve in the main valve body for free movement, and check the valve springs for wear and damage.
Check the needle bearings on all shafts for seizure, wear, and damage.
