Figure 4.47. The location of the sensors on the gearbox: 1 – torque converter turbine rotation speed sensor; 2 – motion speed sensor; 3 – solenoid valve for cooler performance control; 4 - pressure sensor in the pressure line
The following sensors are installed on the automatic transmission (Figure 4.47):
- torque converter turbine speed sensor 1;
- speed sensor 2;
- solenoid valve 3 for cooler capacity control;
- pressure sensor 4 in the pressure line.
Removal of the speed sensors, the pressure sensor in the discharge line and the coolant capacity control solenoid valve is carried out without draining the oil and removing the automatic transmission.
