Condition
Technicians may experience difficulty in removing the connectors from the Park/Neutral Position Switch, usually when trying to remove the switch
during transmission service. In rare cases, customers may also report switch related electrical conditions, such as improper or no shift indication, or no
back-up light operation.
Cause
High ambient heat may cause the sealing compound in the switch to melt and flow into the connectors, sealing the connectors to the switch. This
normally causes no customer concerns, but may cause an open circuit in rare cases.
Correction
In many cases, the switch can be removed and reinstalled without removing the connectors. If the switch is being removed as part of transmission
service, and there are no switch related conditions, the switch can simply be reinstalled.
Some applications have a mounting bolt behind the connectors. The switch will have to be removed and will probably be damaged in the process.
The connector pigtails use wires which are all the same color. Use the old connector as a pattern to ensure that the new wires are connected to the
harness correctly.
Important:
This switch is in a wet area. It is very important to solder the wires and use heat-shrink tubing to ensure water-tight connections.
