Auto Trans Stuck in 1st Gear

[JWBroncoATL]

This just happened to me. Bronco would not upshift coming out of a stop at a light.

I thought maybe I accidentally was in M. I was not. I was in D.

I shifted to N and back to D. It would not upshift.

I pulled over, put the transmission in P and cut the engine and re-started the engine, put in D and drove off. All a-ok since.

Did you ever figure anything out?

sorry if I’m being dense, but I didn’t understand your story about buying more transmission fluid. Is the Bronco a sealed system and you can’t add more fluid?

Dipstick is on the side of the transmission and only accessible underneath.
