Customer Question
After hauling out of...

After hauling out of red clay today the truck wouldnt pull out at all but when on the road run good. Check transmision light came on multiple times shut the truck off light goes away. It's like the truck has no low end power and once it gets out of third gear has full power

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Truck Mechanic I'm going to connect you with knows all the tricks and shortcuts.

Ok

Mechanic's Assistant: Anything else you want the Truck Mechanic to know before I connect you?

It has water in the fuel which I pretty sure time for injector/cups

Hello and thank you for using Just Answer. My name is ***** ***** I will be assisting you with your question. I am sorry that you are having issues with your truck. I know this can be frustrating. On your issue. If this seems like the hesitation is between 1100-1400 rpms and then the power is fine over 1400 then it is either a leaking injector or an issue with the needle control valves bad in the injectors and they will need to be replaced if there are none leaking. On the trans fault. This could be linked to the engine not putting out the expected torque needed in order to allow the trans to put the proper power output. This happens when the engine lacks power. Another few things that I would look at is the egr differential pressure sensor. I would make sure the sensor is not stuck in range which is monitored with a scan tool. This will cause this type of concern as well. I hope this helps you on the right path. Thank you and have a nice day.
