Can you drive without a shift solenoid?
The short answer is that, yes, you can usually drive a car with a bad shift solenoid. Granted, it might not shift past a particular gear, but you should be able to drive it for a short period of time without causing any serious damage.
Can a shift solenoid be bad and not throw a code?
Ignoring a warning light or code being thrown by a faulty transmission shift solenoid can lead to serious problems, such as running your vehicle in the wrong gear for your speed and conditions. If the problem is in the wiring, simply replacing the shift solenoid will not fix the problem.
How do you drive with a bad shift solenoid?
The short answer is that, yes, you can usually drive a car with a bad shift solenoid. Fluid pressure control should continue to function in the gear with the working solenoid, but you should avoid putting any serious stress on the transmission — towing or drag racing — just in case.
What happens when one shift solenoid malfunctions?
Your TCM tells your transmission how and when to shift by opening one of these solenoids to allow transmission fluid to pass into the transmission’s hydraulic control section for the specific gear. If one shift solenoid malfunctions, the gear that it’s intended to control won’t work properly, if it even works at all.
When to replace a transmission pressure control solenoid?
These situations normally end with complete transmission failure. When the diagnoses is a failed transmission pressure control solenoid, the solenoid must be replaced. Replacing a transmission pressure conrol solenoid can be done by most any auto repair shop, automobile dealership service center or you can do-it-yourself “DIY”.
How can I tell if my transmission solenoid is bad?
To read the trouble codes from the transmission control module, you need an OBD2 scanner to read generic and enhanced trouble codes. Most cheaper ones can only read the codes from the engine control module. If the transmission control unit recognizes any shift solenoid problems, it may cause the transmission to shift very slowly.
How many volts does a transmission solenoid have?
The shift solenoids are spring loaded with a coil inside. It depends on the car, but there are normally has 12 volts to the solenoid all the time and the transmission control unit sends ground to the solenoid when it’s time to open and releases the pressure.
