OD light blink with no codes?

OD light was blinking. I scanned with autoenginuity and it showed no codes. I hit the clear codes icon and no more blink. I have 2 issues, scanner and trans.

The light has blinked before and I reset it by disconnecting the battery and I replace a burnt out bulb in the light above the bed. The burnt bulb and od blink have happened twice. I read the burnt bulb can cause a code and the tranny to go into limp mode. Is this true? I am wanting to get my tranny as good as I can I am thinking deeper pan(with temp port), tranny guage, shift kit(reccomendations?) and trans cooler(tru cool). Any suggestions on set up or order of battle?

On the AE scanner. It pulled a code for my UVC harness needing to be replaced so are their other settings I need to change? What is my next step with the scanner?

Re: OD light blink with no codes?

I suspect that there is a code but your AE can't read it.

A deep pan will only empty your wallet. I don't know of any benefit to the transmission from a larger pan. And reading the trans temp in the pan is the worst place you could read it. Use the test port on the driver's side, towards the front, just above the pan. This will give a much more accurate idea of what the internal temperature really is.

I recommend a 6.0L transmission cooler. The Tru-Cool is a distant second place.
