I-shift trouble

Hey pablo,help me please got problem with my ishift trying to shift gear but its not engaging gear changes on screen but little arrows in front.Fault code says
MID 130 PSID 29 FMI7

 

code

 

I did the same by replacing the engine crank sensor and engine pressure sensor. I swear companies like TEC here in the west coast told me the entire harness is flooded with oil when in fact when I looked myself, the engine crank pressure sensor was shooting oil! Obviously we replaced that. Also there are air line fittings on the transmission. Be sure they are not leaking by spraying soapy water onto it when the operating air pressure is achieved. If there is an air leak, there wouldn't be enough pneumatic shifting power in filling those sensors and you will get codes in regard of sluggish response. The computer determines that by incorporating position feedback sensors on the cylinders that actuate the shift forks themselves . Remember, the force behind the shifting is the air that goes into the cylinders. Now if there is any other mechanical fault inside that hinders the shifting could also be an issue. Always replace your transmission fluid per manufacturers recommendations especially on these I-Shift units.
