Is the number 2 speed sensor solenoid on 92 Camry transmission necessary when replacing with a 94 without one?
No, the number 2 speed sensor solenoid on a 92 Camry transmission is not necessary when replacing with a 94 transmission without one. The 94 transmission does not have a number 2 speed sensor solenoid, so using a transmission without one will not affect the functionality of the vehicle.
