The automatic transmission makes driving so much easier for people. You don’t have to switch gears manually as you do in manual transmission vehicles. When you step on the gas pedal in an automatic transmission vehicle, the proper gear ratios are selected automatically in order to make the wheels move at the demanded speed. The driver doesn’t need to do anything other than step on the gas pedal and steer the steering wheel.
Every automatic transmission contains a component known as a transmission control module. The main function of the module is to keep track of the transmission control sensors and relay the information back to the engine control module. That way, if there are any problems with the transmission controls, the engine control unit can detect them.
You can verify the problem by running a diagnostic scan on the engine control unit and seeing if trouble code P0700 comes up. If it does, then you definitely have issues with your transmission controls. This is a very serious problem that you should not wait to fix because it can put your safety and the safety of others at risk. You’re also risking further damage to all the components associated with the problem. It is better to be safe than sorry.
The first symptoms may include the Check Engine light illuminating and a poor fuel economy. Then you’ll experience drivability problems and transmission shifting issues, which are much worse problems. Your vehicle’s fail-safe mode will probably turn on as well. By this point, you must take your vehicle to a mechanic and have them fix the problem. It is the only way to save your transmission and other components from getting damaged permanently.

The most common causes of transmission control issues include a bad valve body, bad shift solenoids, a bad transmission control module, or perhaps the transmission has gone bad. Let’s just hope the transmission is not defective because that’ll cost you thousands of dollars to replace if it is. The best-case scenario is that your control module or solenoids have gone bad. Those are much less expensive to replace than your transmission or valve body.
