Tightened battery cable and only 0766 code appears but overdrive is gone. Any recommendations welcome. Thanks.

There are a few things that could cause this issue as it is basically is saying that the commanded gear is not actually going into this gear.

So we need to run through this testing and find out what is causing it. Unfortunately it is not the easiest testing or repair if this is a shift solenoid or valve body but we can work through it.

Let me know if you have questions. Thanks
