I was driving my truck around 3-4 days ago and suddenly the gauge cluster died. I pulled into the nearest parking lot and it just happened to be an autozone parking lot, had one of my batteries tested and they said it was bad. Replaced it, truck idles at 800 now, battery light still on but drove home. Got to my apartment's parking lot, turned truck off and decided to see if it would turn back on, it didn't. The only stored code is P0884 for the TCM. Jumped truck to drive my sister to work and right after I dropped her off, gauge cluster shut off an the truck couldn't get out of first gear. Hobbled the half mile to Walmart, got another battery and went to orielly's first thing in the morning for an alternator. Replaced alternator and the truck still has the battery light on and idles high. Looked for worn wiring and couldn't find any, what's my next step? Also first post on this forum so I'm sharing a pic of my truck for everybody.

Hello ex_burst and welcome to the forum from N.E. Indiana!! Sounds like a communication - connection problem. I know this probably sounds redundant, but unplug and reconnect connectors under dash and by the E-brake. Good luck and hope it helps!

I've actually fixed the issue and while I doubt it, maybe your problem is the same. Turns out a small piece of my old alternator's plastic connector broke off and was stuck way inside the connector itself. I probably would have snipped wires to do the bypass but was triple checking and the lighting was just right and I realized what was going on. It's not much but if you're still having issues I sorta made myself an expert on this one specific problem so if you have any questions I'd love to help.
