i can HAVE a 93 dodge caravan at work that needs replacement. body and interior are in tough shape, it has a problem somewhere in the driveline (limits safe driving speed to about 25 mph!) , and the 3.0 has over 200k on it but seems to run ok. initially i was just going to yank the computer, relays and harness out of it but now thinking i might just haul it home. wondering what parts are interchangeable, if any, with my 89 van or 87 charger? it has a rebuilt auto in it. don't know if its a 3 speed or 4. any way to ID the tran type easily (other than driving it!)? last thing i need is another "repairable" vehicle stashed behind my garage. mostly interested if the auto tran will work with the earlier common blocks.
