Hi DOZER621,

If you would like to conduct the scan yourself here is a link to an article that features written step by step instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com

I got a code reader, but the truck did not throw any codes. I am at a loss as to what the problem is.

Can you take a video of the problem and give us the link here. It tough to visualize what is going on.

Please check fuel pressure with a gauge to see if it is weak.

What is the normal range for fuel pressure on a 5.7L Hemi?

58 psi +-2 no lower key on or at idle

Would low fuel pressure cause weird gear shifts?

low fuel pressure can cause all sorts of things if engine doesn't run right neither will transmission
