P0768 is a diagnostic trouble code (DTC) for "Shift Solenoid D Electrical". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
When the PCM in your vehicle records trouble code P0768, it means that it has found a problem in shift solenoid D.
Your vehicle’s automatic transmission makes use of shift solenoids to transfer fluid through the hydraulic circuits and change your gear ratios. You need varying gear ratios to accelerate and decelerate, and also to ensure that your engine is working properly and you are getting good fuel economy. If the gear ratio recommended by your vehicle manufacturer is not compatible with the actual ratio that the PCM detects, then a P0768 code is stored, and your Check Engine Light may come on.
The most common causes are: * A bad shift solenoid * Transmission problems * Low or dirty transmission fluid * A bad TCM (transmission control module)
You might drive for a very long time without seeing any symptoms other than a glowing Check Engine Light, but it might be best not to count on that. You could also experience the following:
The first step in diagnosing the P0768 code is for the mechanic to use a code reader and an ohmmeter to evaluate the computerized system in the vehicle that regulates speed inputs and transmission outputs.
Next, the mechanic will:
Mechanics sometimes assume that the shift solenoid is faulty and replace it when in fact, the problem is nothing more than contaminated transmission fluid. Sometimes, too, they may replace the PCM, assuming that it is not working properly, but the fact is that your vehicle’s PCM is hardly ever likely to fail.
Difficulty shifting can be problematic, especially if you are driving at highway speeds. If you are just driving around town, failing to get into proper gear is not likely to get you killed. On the Interstate, though, it can be a very different matter. So, think about your driving habits, and if you are driving in areas where you may need to accelerate or decelerate quickly, get this issue dealt with right away.
You might not even need a repair – it’s possible that just topping up your transmission fluid could correct the problem. You might need repairs to wiring and connectors, though, or a new shift solenoid, or very rarely, repairs to your PCM.
Even if your shifting issues are not causing you huge problems, it is best to get them corrected. Otherwise, you could end up with costly transmission repairs later on.
