Default Truck problem. What was wrong, and did it really get better?

sounds like the transmission went into what's
called "limp home mode". That happens when
I knew the term limp mode, but I had forgtten it when I needed it most.

Very useful for googling:

Limp mode is actually a safety measure that prevents the Dodge Ram 1500
from being driven if its computer detects a fault in the transmission.
... To get the Dodge Ram 1500 out of limp mode you need to stop and
shift to park. Turn the car off and wait 30 seconds, now turn it back on
and it will be out of limp mode.

I thought about turning the car off even when on the Xway and I guess
I mistakenly decided not to. Once I got to the exit a quarter mile
away, I could have done it there too, but by this time I'm thinking,
Hey, 30 mph. Not bad.


How do I get my truck out of limp mode?
Restart Engine

If your vehicle goes in limp mode while driving, find a safe place to
stop and restart the engine. Allow the car to stay completly off for at
least one minute before you restart it. In many cases, this will reset
the limp mode and allow the vehicle to operate normally.Mar 10, 2020


So it's no surprise it did better after the 7-11. I made sure to get a
receipt for the xmission oil. So even if I don't need fluid, I"m not
going to expect a small business like that to give me my money back (so
I won't be disappointed) but I think the'll exchange it for food or
something.
a whole bunch of possible things go wrong,
so it locks itself into second gear so that
you can get off the highway and, well, limp
to a repair shop.

Sometimes these things are a momentary hiccup,
which, once they reset, are a-ok for the duration.

Other times, though....

There are lots of diagnostics to check out
what happened. They might, or might not,
give you the answer...


Were there warning lights turned on, warning messages on the dash?


I don't think so. I dont think there is a provision for messages at
all.

The modern vehicles I'm familiar with, they don't go into limp mode


Is 2001 modern?

without setting obvious warnings on the dash. For that matter, modern
vehicles would likely put up some kind of warning if you had it in second
and were driving too fast on the highway.



The one I had that did it was a '94, so apparently Dodge did it for
quite awhile.
