I recently purchased this Acura MDX 2003. It drove fine for awhile and then it started missing out so I pulled the head and it had a burnt valve in 2 cylinder. So I did an engine overhaul it had sort of high mileage so I did main bearings, Rod connector bearings, rings and completely redid the top end new cams new valves New keepers send the heads to the machine shop when I got it put back together It i started going the D 5 light started flashing and it would go high in RPMs before switching gears so i replaced all trans fluid and gear oil. no help I hooked it up to scanner and it says number 4 pressure switch circuit high so I replace the pressure switch i replaced all the pressure switches, still says circuit high. I check for voltage at the connector and I get voltage so now I'm lost need help.
