Circuit description
WARNING: This page is about a different variant/trim than selected.
The line pressure control solenoid ASSY (SLT) is controlled according to the duty signal which is predetermined by the transmission control computer ASSY based on signals from the accelerator position sensor and the transmission revolution sensor (SP2, NT). This adjusts line pressure to meet the throttle opening angle and engine output. The transmission control computer ASSY detects slippage of clutch, etc. based on the revolution speed of the transmission revolution sensor (SP2, NT).
