2. SYSTEM DIAGNOSIS

1) TCU
The transmission control unit (TCU) controls transmission gear selection via variable bleed
solenoids and On/Off solenoids. The TCU operating voltage is 8-16 V, with current draw
typically being less than 4 amps but reaching as high as 10 amps during gear shifts.
As the mechanical components of the transmission change due to wear etc, the TCU adapts its
shift data to accommodate these changes and maintain shift quality over the life of the vehicle.
If a transmission component degrades to a point whereby the TCU is unable to adapt its shift
data to maintain shift quality, the TCU will set a DTC.
