I believe you also need a A/S/2gnt manual tranny because you have to swap the gears out of the neon tranny and put them in the other bellhousing. You will need the ECU from a same engine year you have, but manual. (95). RyaN95i4, is doing the exact same thing you want to do right now. It a 95 avenger and he is putting the neon tranny in it. He has done the research and your should talk to him. He is on asog, asec and groundfloormotorsports. Get a hold of him. I believe the 95 is the most expensive one of the bunch to do the swap in. I did it for $1000 in my 97.
