Range Valve Removal
1. If equipped, remove the Protective Cover by pulling up 
on the release tab.

the vehicle. When air pressure has been relieved, dis-
connect the Transmission Harness from the Range 
Valve.
Note: The harness should be removed from the Range 
Valve cable tie prior to removing the cap screws.
3. Using a 5/16” socket, remove the 4 mounting cap 
screws from the Range Valve.
4. Lift and remove the Range Valve from the housing.
Caution: Do not use a hammer to loosen the Range 
Valve in the housing or it could be damaged.
