Heading home after work yesterday had quite a scare. CEL came on and the truck wouldn't shift up out of second gear. Tried manual, tow/haul, shut her off and restarted a couple of times. No change. Nursed it to the dealer. They checked the MAP and found it ok then did a TSB# 07293 TCM flash. Anyone have any particulars on this? It's been really cold up here in Anchorage, O F and below.

Thanks guys!

I have no listing on that code in any of my information.

Hi Mike, I show the code to be "O2 sensor circuit no activity detected(Bank 2 Sensor 2)" at least for engines up thru LLY. I'm wondering if anyone has info on the TSB that might give more context to what the TCM flash changed.

Thanks for the response though
