How does the TCM perform gear shifting control?
How does the TCM perform gear shifting control? The TCM performs gear shifting control according to driving conditions by using the shift point char- acteristic data stored in its memory. Appropriate solenoids are operated at the proper timing corre- sponding to the shift pattern, throttle position, and vehicle speed for smooth shifting. How is transfer duty solenoid controlled by TCM? The transfer duty solenoid is controlled by the TCM. The TCM changes the solenoid controlling duty ratio according to driving conditions. The transfer duty solenoid creates the transfer pressu re from the pilot pressure. The transfer pres- sure is applied...
