So far as I know there is NO aftermarket engine computer that will control Chrysler transmissions. Only the OEM computer I think. So this leaves you with having an OEM one reflashed.
OP if you are using an "old school" 727 there is no computer connection to that. Likewise if you want an OD you can use the earlier hydraulic, not electronic A500/518 overdrive with the 3 wire connector to control the OD
There was a guy on here did a Megasquirt G3 hemi in a Duster. Wade Kuell??? Look it up..........Here:
