Ran transmission 2 1/2 quarts low

81 is the code i suspect to turn on the check engine light

2-3 shift selenoid circuit fault

Code 81:
·" When the PCM commands the 2-3 Shift Solenoid “ON”, but the voltage on Circuit
1223 remains HIGH (system voltage) or LOW (Less than 1 volt) when solenoid is
turned “OFF” for two seconds or longer. The “MIL” will not be turned on, TCC
will be inhibited, maximum line pressure will be commanded and 2nd and 3rd
gears only are available."

So how do i fix this. Pcm problem? Or solenoid problem.

You got me. I just try to share data to hopefully assist the guys that do know so they don't have to reference it if needed.
