4l60e not getting info from ecu I pulled my383 from my 3rd gen camaro and put it in a 94 yukon. Using a fitech 400hp fuel Injection setup. Inadvertently cut the wires sending information to the ecu operating the trans. Did NOT cut tps. It is piggybacked in correctly. How do I bypass the map and I guess o2 signals to help the transmission operate correctly without having to buy a transmission controller.

As far I as can tell the Fitech EFI does not support any transmissions. The PCM from your 3rd gen will not work with (talk to) your Fitech. I see that Fitech sells a "stand alone" GM transmission controller; it has a method of tapping into your TPS, but generally two ECUs cannot read from the same TPS. Also that trans controller seems to be very primitive. Good luck solving that. Best bet will be to get support from Fitech; maybe they have a forum.
