Electronically Controlled Transmission Communication Circuit

ELECTRONICALLY CONTROLLED TRANSMISSION (ECT) COMMUNICATION CIRCUIT - SOLENOID # 2


CIRCUIT DESCRIPTION
When driving uphill under cruise control, in order to reduce shifting due to ON-OFF overdrive operation and to provide smooth driving, when down shifting in the electronic controlled transaxle occurs, a signal to prevent upshift until the end of the uphill slope is sent from the cruise control ECU to the electronic controlled transaxle.

Terminal ECT of the cruise control ECU detects the shift change signal (output to electronic controlled transaxle No.2 solenoid from the electronically controlled transaxle.

If vehicle speed down, also when terminal electronically controlled transaxle of the cruise control ECU receives down shifting signal, it sends a signal from terminal OD to OD1 to cut overdrive until the end of the uphill slope, and the gear shifts are reduced and gear shift points in the electronically controlled transaxle are changed.
