Will any flashable TCM work, or is there a particular part number that is best for a 91 New Yorker?

From my understanding any flashable one is fine as long as its updated, and it sounds to me like the newer part numbers simply shipped with newer software from the factory.

Is this the case? Is there any particular part number that is in some way better than another? Also, can I use a TCM out of a van or LeBaron or something, are those also compatible?

Thanks for any information to help me clarify this.

Ok, thanks for the reply.

What if an older vehicle has the same part number? For example, there is an 89 New Yorker in the yard nearby, it's got a finned TCM. Could it have been updated? Or, do I still need one from a 90-91 car only?

Thanks

Perfect. Thanks for clearing all that up for me. I'll see if I can't find one, otherwise I'll get back to you... but there are about 5 or 6 yards in the area so I'm pretty sure I can dig one up, we'll see.
