VW Jetta Automatic Trans. wont engage!

\015 I replaced the engine and put it all back together and now the Automatic Transmission wont engage at all. When I rev it to around 3500 rpm and higher it will creep a little with very little torque. The only code it's throwing is 00652 which is Gear Monitoring: Implausible Signal. Does this sound familiar to anyone? Any story's?\015 Posted / edited by AnonymousUser on : 19-02-2018

Answers :

The engine\012and automatic transmission in this vehicles drive train\012are fully electronically controlled by a computer called the PCM\012(Power Train Control Module). Whenever a problem like this occurs the\012computer stores a record of the problem (there are of course some\012exceptions to this, like the fuel pump, engine coolant temperature\012sensor and MAF sensor for instance) in the form of a fault code in\012its memory, to read these fault codes you must have the systems\012memory scanned with a special tool. Once the fault code(s) are read\012you then must perform the appropriate diagnostic testing to find and\012resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A\012TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR\012HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
