this Transmission Control Unit is not re-programmable
If you do not have the correct hard- and software for testing you should not order this TCU.
For testing the function it would be helpful to have a Mulitplexer.
A Multiplexer enables you to connect any OBDII diagnosis interface or flash-unit with a dismantled transmission contol unit. The Multiplexer was developped in order to test the TCU electrically.
For diagnosis only you may use VCDS, VAG-COM, etc.
