Jeep Grand Cherokee 2012 5.7 V8 Gearbox Not Work After ECM Replace

Hi folks,

This USA specifications Jeep Grand Cherokee 2012 5.7L V8 car has a front accident that touched the ECM.
After that the car was starting but was behaving erratically and after sometime did not start anymore (as the owner says).
The other technician swapped ECM and the engine starts but the gearbox is not active.
What do I have to do to solve this problem?
Probably there is something to do like synchronize the new (its an already used one) ECM with the other ECU in the car or with the gearbox?
What tools do I need for that?
Is the tool WiTECH MicroPod 2 Diagnostic Tool V17.04.27 For Fiat Dodge Jeep Chrysler suitable for the job?
Or do I have to go with Abrites AVDI or other tool (thanks for sharing the name of it)?

Please help.
