Question about 2003 Hyundai Santa Fe
The following parts have been replaced in attempt to solve electrical malfunction. PCM, relay for transaxle,valve body and solenoids. this unit will work great with Tran-X. If you try to drive vehicle on vehicle PCM it will start locking up in third gear after driving 1 kilometres and gets progresively worse.while monitoring 2nd clutch amp flow with Tran-x I found it would turn solenoid on but then start dropping amps and bring on the 2nd clutch and bind up.

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

have u had pcm checked by specialist company?
sounds like it is either getting the wrong info ir its giving the wrong info which is causing confusion.
I assume you have had it scanned and cleared/ checked all codes.
i also assume the battery / alternator charging sytem is all functiong correctly and is correct for the car. some cars are very fussy about the amperage in the system.
check it out
