My Daughter has a 93 3.0 Duster that the A-604 OD trans did the "locked in Limp Home mode" about 8 months ago. I took it to two tranny shops and it was trashed inside. I bought a 90 Voyager with the 3.0 and A-604 for parts. The 93 has no speed sensor on the right axle housing but the 90 does. I know the 93 has Input and output sensors on the front that let the computer know the speed and the puter does the spedometer. What I need to know is will the 90 trans work? Is all I need to do is plug and play? DaveJ
