1998 JAGUAR X308 transmission

Operation
• NOTE: The rotary position switch is NOT adjustable.
The position of the gear selector lever is detected by the range sensor; a system which consists of two sensors (switch
systems). 1. 1. The rotary position switch, which is located on the RH side of the transmission case and is coaxial with the
selector shaft.
2. 2. The D to 4 (micro) switch, which is mounted in the 'J gate' assembly.
When the selector is moved across the ga te to engage 4, or back from that side towards D the selector cable does not
move. In order that this change of state be registered by the TCM the D to 4 switch is incorporated.
The rotary switch in isolation provides a 4-bit code, which, when added to the D to 4 switch becomes a 5-bit code. The TCM
will make a failure judgement if it detects an 'illegal' code.
