The other day I stopped at a stoplight in my 2003 Dakota 4X4 Quad cab w/V8.
with about 45000 miles. Transmission was serviced about 10000 miles ago.
When I took off the transmission was slipping, I looked to see if I had
bumped itout of gear or something and noticed the "square" indicator light
that tells
you what gear you are in was "missing".
I shifted to what should be 2nd gear and the transmission "shuddered" and
took off.
When I got across the street, I stopped and shut the engine off and checked
for codes.
After I restarted the truck the indicator light came back on, the
transmission  shifts normal and everything seems to be fine, with no codes
showing
and no  slipping.
Does anyone have any ideas where I should start checking for a bad
connection?

TIA,
Tom R.
