AX4N to AXOS Swap

Daughter wrecked her 01 Taurus U code, axos, have available an 00 Sable with Ucode, ax4n (Bad head gasket and tranny run dry) and want to do a cradle swap and junk the rest of the Taurus. I figure I have to swap PCM and engine bay wiring harness, but the connectors under the dash don't have the same pin patterns. Is the cabin wiring harness a standard item. or does that have to be swapped, too? What kind of trouble will I run into doing this, and what else needs to be done?

Sorry club members, haven't figured out how to start a new thread????

is this normal or final drive? Also, is "axle" ratio the same as "rearend"?

thanks!

There's a list of what cars had which ratio. Also, kind of, but it's a chain inside the transmission instead of two gears in a rear diff.

Issue that confuses it the OD is a ratio less than 1. So multiply the axle ration time the OD ratio to get combined.

OD likely 0.694 but depends on year and trans type.

So when you say tuning, can this be done at a dealer ?
Just to get the pcm to respond properly to the new inputs, will Ford do the programming for me ? Or do I need to look for someone who does custom work ?
FYI, newer trans installed and having some TC quirks.
Thanks !!

Yeah I actually just got off the phone with the local dealer...said they don't get involved with any type of modifications like that. Generally just replace with new of the same.
I'll have to locate a tuner and someone who knows what to do with it ;-)
Thanks again !!

AX Transmission.

I recently had a re-man transmission, and torque converter put in my '03 Taurus. According to the installation information the new transmission is listed as a 4F50N, replacing the AXOD. However, the oil pan on the new transmission is stamped AXAN. I know these transmissions are all of the same family, but I am curious, do you think it's a 4F50N, or is it a AXAN? Also, any ideas as to the final drive ratio? Thanks.

4F50N replaced the AX4N in the early 2000s.
