Red lightning bolt of death

Almost sounds like the OP's oil press wire must have been shorted.

Your issue IDK. Have you pushed down all your truck's fuses in case some are lifted up? And I'd probably wiggle and inspect the bundle of wires & connectors below the TIPM. There have been other owners who've had corroded pins and even badly corroded wires behind the TIPM connectors. There have been a few owners who needed to replace connector pins and splice out wires at the connectors. If nothing else, if you haven't done so, it would be worth a visual inspection of the TIPM connectors & pin to rule it out.


I'm just tossing out ideas, I don't know what your specific issues is. Sucks to have them. Hope you find them soon.

Ok so around 75% of my fuses were lifted up by about 1/16th of an inch. I pushed them all down. I took a video because I have no idea if this is normal. Here is the video of me pushing some of them down. After pushing them all down the error codes still remain.

I also found that my gearshift control cable (68359786AD) was unplugged. I replugged it to no avail. Looks like it had maybe been unplugged a long time due to the amount of dirt on the connectors... is it possible that my truck would have been fine without it plugged in? I do see I'm having error code U1428 which is from the TCM. I notice this cable has an o-ring - maybe I need to add fluid when replugging it? perhaps I lost fluid when it came unplugged

My problem was very similar to @Zane2014 it was chewed wiring leading to the oil pressure sensor, likely a rodent ate the insulation off the wires. Paid a local shop 1100 to diagnose and repair. Sadly the chewed wires were underneath the manifold right at the connector to the oil pressure sensor. They replaced the connector and spliced and heat shrinked it. This video was very helpful to me.
