Hydraulic Control
WARNING: This page is about a different car, the 2003 Jaguar XJR, 2002 Jaguar XJR, and 2001 Jaguar XJR. However, it is still accessible from the selected car via links, so may be relevant.
The selector valve is operated directly by the J-gate and directs fluid flow for P R N D .
Of the four solenoid valves, 3 control shifts and 1 controls converter lock-up. One control valve controls modulating pressure and the other shift pressure.
Regulating valves are used to maintain/control pressure for lubrication, normal operating functions, and the supply to the control valves and shift valves.
In the event of a system fault, the TCM will adopt "limp home" mode.
