AUTOMATIC TRANSMISSION SYSTEM L4 Position Switch Circuit

DESCRIPTION

The No. 1 transfer indicator switch (L4 position switch) detects the gear position of the transfer shift lever.

Moving the transfer shift lever to L4 turns the L4 position switch ON. Then the TCM cancels operation of the lock-up clutch.
