I installed new ECM I guess that’s what you call it
Everything Is running OK and shifting OK but when I’m in park I have this on my dash the gear symbol is halfway on and then I have a manual and auto symbol on never had before
I called the dealer they said it was just plug and play is there some transmission relearn I don’t know about?

You have to do a clutch relearn. The new ecm needs to "learn" the clutch freeplay to engage properly. The "u" means the oil temp needs to be raised by letting the engine run. Then youll need to shut the key off and start the relearn procedure.
Clutch relearn:
Unit in Park, Key off
Key on
Full throttle, release (twice)
Full throttle and hold pedal down
Shift from Park to Low to Park to Low to Park (Make sure dash shows "L" and "P" when moving lever). This has to be done quickly
Release the throttle
Start the unit
Dash should flash "--" every 2 seconds for up to a minute. You'll hear a clicking in the engine
When the relearn is done, the dash will go blank (no gear position or AT/MT)
Shut the key off and start the engine again.
Dash should be normal now.
Engine oil temp has to be pretty warm to make the relearn possible. Once the "U" dissappears the temperature should be warm enough.
