Powershift Gearbox - 4 Speed
Introduction
This section explains how the electrical system works when
the following gearbox functions are operated:
1st, 2nd, 3rd and 4th gears forward
Neutral
1st, 2nd, 3rd and 4th gears reverse
Transmission dump
Park brake switch
The 4-speed powershift gearbox is controlled using
conventional relays. The relays at A are operated via the
column mounted gear and forward/reverse lever B. The
transmission dump switch C or park brake switch D also
operate a relay at A. The contacts inside the relays energise
the gearbox mounted solenoid control valves E.
Diode ‘gates’ F are also used as logic switches.
To access the relays and connectors it is necessary to
remove the front/steering console panel X and side panels
Y, refer to Section B for the correct procedure.
