Phone call session started
If the switch is new then you will also want to test and inspect the wiring harness for any damaged wiring or connectors and be sure that you have continuity in the wiring harness in that circuit. Also you want to check for power and ground at the solenoids for the two speed control valve to see if the solenoids are powering up and actually working to send pressure to the two-speed Drive Motors. If the solenoids are not powering up to switch between single and 2 speed and the two speed module is getting signal from the switch then yes it can be a problem in the two speed module.
