So From what I understand the 98 GS400 ECU, The Trans is a seperate/different part of the ECU. I bought a Automatic ECU emulator to remove all the DTC. If you go onto facebook and search for Toyota ECU security off, conversion adapters, parts. You will need to request an add. The part is $100 shipped from Mother Russia.

For the Speed sensor, i believe you can tap into one of your speed sensors.
