Figure 4.47. Location of sensors on the gearbox: 1 – torque converter turbine speed sensor; 2 – speed sensor; 3 – electromagnetic valve for regulating the cooler capacity; 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;
- sensor 2 speed of movement;
- electromagnetic valve 3 for regulating the cooler capacity;
- pressure sensor 4 in the pressure line.
