Hello, I'm Richard! I'm a Chrysler, Dodge, Jeep tech with 23+ years experience & I'm going to try my best to help, so let's get started!
What year, make, model and engine do you have? I'm assuming you have an older Dodge Ram with a diesel is that correct?
It sounds like your PCM is down. A faulty crank sensor can cause no charging, no overdrive and no tach, but it won't affect the speedometer.
Let me know and we'll take it from here.
Thank you,
Richard
