Your 89 will have an AOD transmission (non electronically controlled). They are all
pretty much the same except for most Lincoln applications. The Lincoln AOD is about 1"
longer.
Used AODs are a real crapshoot. If you feel the car is worth keeping, rebuild the
one you have. Make sure the tranny shop replaces the failed Throttle Valve Cable
grommet that caused your trans to fail.
