2011 Peterbilt Automatic transmition Does not Rum

Put a manual in the thing. And run it.

 

Fixed it for ya..

 

Check for fuses in or near the batteries for the transmission TCU and make sure they are good. Other than that, there really is literally nothing we can do for you. You are dealing with electronic engines and transmissions that need a computer connected to it to see what codes are being logged or even if the part is booting up at key on.

 

bingo. You have computers in a proper shop. That computer talks to your truck's computers THEN you might understand what the problem is. If your truck's transmission is really bricked you might have to tow it to the shop before anything.

I hate to be difficult, but autos are nice when they work. But when they do not? Oh boy... Way better to have a manual.

 

Personally, auto-tragic transmissions have their place........in a four wheeler or personal vehicle, but if you want to make money and keep it in your wallet, get rid of the auto crap before it sinks your ship before you even left the dock.
