Tacoma Extra Cab 4WD L4-2693cc 2.7L DOHC MFI (1997)
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 electronically controlled transmission occurs, a signal to prevent upshift until the end of the up hill slope is sent from the cruise control
ECU to the electronically controlled transmission.
Terminal ECT of the cruise control ECU detects the shift change signal (output to electronically controlled transmission No.2 solenoid) from the
electronically controlled transmission.
If vehicle speed down, also when terminal electronically controlled transmission of the cruise control ECU receives down shifting signal, it sends a signal
from terminal OD to ECM to cut overdrive until the end of the uphill slope, and the gear shifts are reduced and gear shift points in the electronically
controlled transmission are changed.
