Looks like even the rims got swapped out.
Is there any stray paperwork in the glove compartment? I found my prior guy (and his parole officer) that way.
I was heading down the entrance ramp to the highway going to work, giving it the usual Italian tune-up. At the bottom of the on-ramp, every blinkenlight lights up on the dash, and into limp mode I go. Fortunately there's this handy place to pull off away from traffic a quarter mile down the...
I've found the MT82 to be the most forgiving of going into first gear at speed of any manual transmission I've used in 40 uninterrupted years of driving stick. They usually seem to have a lockout after some MPH to keep you from dropping into first, but not the Mustang. Want to hit first gear...
When I wring it out on the first few gears (on the onramp, of course), I am not noticing anything that would call attention to the shift knob. I am bad and often rest my hand on the shifter, and it always vibrates some. Maybe I'd call it a "hum," I don't know - it's not like it ever shakes...
Try to back up near a wall or any other obstruction in the back. Family says they can hear the BEEP BEEP BEEP BEEEEEEEP from inside the house when I come home.
Here's a link to my first at-home change:

That's just it - it's not that the physical thing isn't happening, it's that a sensor may not be sensing it.
I've been reminded that there isn't actually an oil temperature sensor; oil temp is kind of inferred from other sensors. But either way: there's a series of things that need to be true...
Right now, you don't know what you don't know. It could be that your oil temp isn't coming up, or the oil temp sensor _did_ stop working, or... something else you didn't consider. That's why diagnostics will help.
I enable LC to see when my oil temp has come up, nothing more. I notice it won't light (ever) when I'm in quiet exhaust mode, or drive mode is in rain/snow. But besides that, once it warms up enough to light LC, I know I can give it the beans.
