1991 Lincoln Town Car Question: TRANSMISSION
Answer #1DaveJHM October 24, 2010, 00:39Master
Your 4R70W (AODE) transmission on this 1991 Town Car has a filter inside the transmission pan. Simply unbolt the transmission pan entirely, remove it (catching all the fluid with a wide pan), and remove / replace the filter. Make sure the o-ring on the tube is present with the old and new filter.
If you pay to have the service done, it is often less than $200.00, even much less in some places.
