P01745 is coming up. Our of no where the 08 Pacifica went into limp mode scanned it and p01745 came up.changed filter and new tranny fluid..code went off but then came back on.goes in reverse ok..in drive but seems pikemits in 3 Rd gear winding out.the tranny was fine before limp.mode. any one else have this issue?

 

SO i see a rest of the line count for the high oil pressure will do it or replace the transmission assembly for a faulty line pressure sensor or pump.

 

So when this p01745 came up the check engine light came to. The fault code came for the oil pressure switch .so I replaced the switch. Now does this code just go of by itself or I need to reset it?
