Hello e36 mechanics, I have a 99 e36 323i vert, auto trans and I have an issue. Been a slow project since 2012, finally got it running and driving on its own power, and my first "long" cruise to a gas station it went into protect mode, with the tranny symbol on the dash. Reset it by disconnect the battery for few minutes and got home, and at the end of the driveway the code came back and lost all its power, I hooked it up to a generic code reader and got a P1750 code. I don't know if I have to replace both sensors or just the transmission, and if I have to completely remove the transmission or if I can access it in the car.
