My van will not stay in gear. Warm or cold and any gear, it comes out of gear when you let up on the throttle. When taking off from a stop, (forward or reverse), you have to rev to about 1800 before it "clunks" into gear. While under load it's fine and no slippage. I serviced the trans with no results. It also threw the code Po731 (gear 1 ratio incorrect). I t also has a code of P1491 that reads: (Manufacture control. Aux.emission system). That is what it says on my OBD11, however the manual states: cooling fan relay circuit??? Thanks in advance!
