The Porsche 98661825502 TCU (TCM / transmission control module) is a used OEM unit removed from a donor vehicle. This electronic module manages shift patterns and timing for the automatic transmission. It supersedes earlier versions 98661825506, 98661825505, and 98661825501. When the TCU begins to fail, symptoms can include harsh or delayed shifts, slipping, or the transmission entering limp-home mode. This part must be coded to the vehicle and VIN by a qualified shop or dealer upon installation.
