Q: Code p0700

Hello. The code you are receiving stands for a transmission control malfunction. This can occur when the transmission control module, shift solenoids, wiring, or valve body damage has occurred. Typically a serious enough error will cause the vehicle to enter a "limp mode" where the vehicle’s operations are limited to minimize further damages. The best way to fully diagnose an issue like this is with a transmission specialist. You may be able to test some solenoids and modules from home with a voltmeter, but most transmission specialists are equipped with technology that can test the systems for them. In a situation like this, having a specialist look into it pays off due to the technology that they have. Attempt to test the resistance and voltage of the modules if you choose, or have the transmission inspected by a professional.
