dodge transmission question

i have a 96 dodge b2500 van 4 speed automatic (overdrive) the trans. just
went out. i have a spare 3 spd auto torqueflite 727 (i think thats what its called) my question is what is the chances of the torqueflite working in my van? i was told i would need to modify the rear mount which i can do and swap driveshafts. my main concern is the electronics that are connected to the 4 spd. will not be connected to the 3 spd. im not worried about the speedometer or the check engine light im just wanting to make the van run, drive, and shift correctly... any help or suggestions would be greatly appreciated.

Chances are you wont get it to run correctly or drive correctly. You may but it is a gamble.Part of the engine fuel and timing strategy is calculated by speed sensor input and turbine speed sensor inputs, something you wont have with a hydraulic controlled trans.
If the check engine light is on you should checkthe codes to see if any could be related to trans operation.Also check the fluid level as it is very important.
If the trans runs low it can skip a shift and then the engine light will come on and the pcm will go into a limp mode operation .You can fill the trans but the limp mode wont clear untill you clear the codes. if the engine light has been on for a while then you have no way of knowing if a new code has been generated since the light first come on.
