OK thank you!There is a gasket ring where the switch screws into the transaxle case. You can seal the threads if this is where it is leaking.
If the body of the switch has started leaking, it will need a switch.
OK thank you very much!You'll lose no fluid replacing the switch. Teflon tape can be a problem as the switch must ground to to the case and it's possible for teflon tape to prevent a ground,
Ahh, thank you very much!Rockauto carries the neutral safety switch. It's under Electrical - Switches and Relays for a 1989 Dodge Spirit.
