68RFE - P0613 Error Code?

**BLACK5THGEN** · 08-13-2022

I just got my truck done, and I have noticed wonky twice now that my truck failed to shift into drive or reverse before I put my foot on the throttle.

I am new to the mechanical side of things.

I want to think it’s the valve body, but I don’t want to put a temporary fix into my truck one time forward; it failed to drive and threw a P0613 error code reset it and only noticed in reverse 600 miles later when my truck was neutrally rolling downhill while in reverse.

I shifted in drive, then reverse, then locked in, but input would be helpful.

The new “transmission tune” was done maybe 4k miles ago when I had ECM flashed.

While we wait for someone more knowledgeable on the 68RFE transmissions, I have attached information on your trouble code.

As you will see, the P0613 code points towards PCM power and ground issues or the PCM itself.
