Common Installation Issues

•

Master Control Valve lines not attached correctly from the filter regulator to the deep range and range valves.

•

Control module software is incorrect. Make sure the control module software has been correctly programmed for the
model, speed sensor rotor (8-16 tooth), and vehicle electrical system (12 or 24 VDC).

•

Vehicle electrical power supply is not connected properly.

Other components/causes associated with a range system failure but not covered in the troubleshooting procedures.

Range Cylinder

•

Debris or contamination in the cylinder

•

Range cover (air leak)

Internal components linked with range shift issues - auxiliary section of Service Manual

First Step

Procedure 1 (Checking the Condition of the System)

Overall system review, checking for loose or damaged wires or connectors.

Turn off the vehicle and keep the key in the 'OFF' position.

Check if the bypass OEM control is turned off, inside the vehicle. Location of OEM bypass control will vary. Please con-
tact OEM for location.

Unplug the negative plug from battery.

Unplug all connectors from TCM and transmission.

Clean all components and harness connections and terminals with contact cleaner.

It is recommended to apply Nyogel 760 on female terminal. Be sure that the product be applied inside the terminal and
the excess removed.

Connect all connectors.

Reconnect the battery.

10. Check if the light is blinking; if yes proceed to

test procedures

Note:

Nyogel is an electricity conductor gel, must be applied with care to not cause short circuit between the terminals.

CAUTION
