A board that replaces the circuit board in a Mercedes EGS51, EGS52 or EGS53 722.6 transmission controller, enabling it to be easily replaced by an LPC4 or other transmission controller not designed as a plug-in replacement for the EGS series.

Comes with a patch harness for connecting an LPC4 for 722.6 control.

EGS5x connector/case not included, but can be added for an extra fee. Currently we have to buy old EGS51 on eBay to destroy to acquire these connectors. If you have a source of second hand EGS5x boxes in bulk or the connectors by themselves please inform us.
