I have swapped an altezza 3sge beams auto engine in my 73 celica. I know the engine and the auto gear has tiptronic however at the time of the swap i had a normal gear assembly without the tiptronic shifting option. My mechanic and ECU guy hasnt worked on a project with tiptronic before and so they cant figure out how the tiptronic can be setup in my case. I now have a mercedez c180 gear assembly with the option of up and down shifting. Does anyone know how the tiptronic can be activated? Is there any wiring on the ecu related to tiptronic? the engine was tuned and worked fine on the automatic assembly i used before. Please let me know how i can help my team get the tiptronic going.
