These TCM variants are used in the \u003cstrong\u003eMercedes-Benz 722.9 7G-Tronic automatic\u003c\/strong\u003e and are recognizable by their \u003cstrong\u003e6-pin TCM connector\u003c\/strong\u003e. The cable ends in a \u003cstrong\u003e15-pin DB15 connector\u003c\/strong\u003e on the device side and is exclusively compatible with \u003cstrong\u003eOBDSTAR readers or programmers\u003c\/strong\u003e.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThe Adapter Cable enables a \u003cstrong\u003edirect bench connection\u003c\/strong\u003e between the OBDSTAR programmer and the detached or installed TCM, without using the vehicle's OBD port. Via the \u003cstrong\u003e6-pin TCM side\u003c\/strong\u003e, the control unit is powered and the \u003cstrong\u003ediagnostic and programming protocols\u003c\/strong\u003e required for reading or rewriting the \u003cstrong\u003etransmission data\u003c\/strong\u003e are transferred. The \u003cstrong\u003eDB15 connector\u003c\/strong\u003e on the other side connects directly to the corresponding port of the OBDSTAR device, allowing signal transmission without additional adapters. This method is mainly used for \u003cstrong\u003eTCM replacement, data recovery, or adaptation reset\u003c\/strong\u003e of the 7G-Tronic transmission control unit.\n\u003c\/p\u003e\n\n\u003c\/div\u003e\n\n\u003cdiv style=\"display:flex;
