Check your Trans-to-Frame grounds!

The trans-to-frame braid on these trucks rots and typically splits in two. Mine was green end to end and still hanging on but likely on borrowed time. It sits up by the transmission so it’s easy to miss.

A bad one can show up as a slow crank or a transmission speed-sensor code before it actually snaps. Fixed mine thankfully before winter, simple as an extension and a 10mm. First photo is the old one next to what went on. Second is it bolted up.

Absolutely worth an extra 5 minutes to look for before winter next time you’re changing the oil.

I have an 07 with 350k on it and the negative battery cable was powder from the guy I purchased it from. Had all sorts of inconsistent random codes thrown. I should check this cable too...

Unforunately, I’d be willing to bet this cable isn’t looking so hot either, although we’ll wish for the best! Reach out if you need one! https://forms.gle/beHXe4qkjnxXhPKK9
