SHIFT CONTROL
K2
HIGH ATF TEMPERATURE DETERMINATION
The ATF thermosensor sends "high-fluid-temperature" signals to the EC-AT control unit if the temperature
of the ATF exceeds 128OC (262OF).
The EC-AT control unit then changes the lockup point (lower speed), available gear, and shift point (higher
speed) without regard to coolant signals. The shift pattern is as shown below.
This function does not effect R or L range.
