Does anybody know about this code and how to fix it..." P1749 Secondary Pressure Solenoid Communication Error (BMW)" I have a 1999 328i 4dr sedan A/T...... I have been having a transmission problem lately. My check engine lights comes on ones in a while, but the tranny fault code always comes on every 15 min minute... (!)D When the wheater is cold ill take about 30-40 min before this (!)D comes on.. but when its hot wheater it takes about 5-15min...I think it has something to do with the transmission fluid getting to hot but then again I could be wrong....pls help..I need your opinion thnx..
