Is your FIPL sensor working? heres some stuff I have saved on my computer on how to test it,
*Hook up the negative lead of a volt meter to the battery ground and the positiove lead to the center GY/W (grey/white) wire which is the FIPL signal wire. I use a paper clip up the side of the wire in the connector. The FIPL must be attached to the wiring harness. Engine low idle speed must be set to specs prior to adjusting the FIPL. Auto 650 in drive, manual 650 in nuetral.
With a warm engine, key on, engine off, measure the voltage at the GY/W wire, if adjustment is required loosen either the bracket with bolts or just use the slack in the Torx screw holes. Now gently rotate the FIPL until you get some where between 1.05V and 1.1V. then tighten the torx screws or bolts which ever you loosened ensuring no movement of volt setting. Rotate the throttle lever slowly to WOT see if you get 3.8 V but not more than 4.3 V. Watch for any dead spots.
The large FIPL mounting bracket can be moved but ensure it is centered for a good rotation. Any adjustment should be made by only rotating the FIPL. If a new FIPL is required, check tang engagement as you take off the old FIPL and then make sure that the tangs in the new FIPL engage the throttle lever properly.
The closed throttle voltage: 1.1 V, ...wide open throttle voltage: minimum of 3.8 V but not more than 4.3 V.

About the only thing you could have done wrong is to either not connect the pipes to the vacuum regulatory valve or connect them the wrong way around.
However I would have thought, even if that was the case, the trans should at least drive in first.
