October, 2002

   Since  the  introduction  of  the  Ford  AXOD  transaxle  in  model  year  1986,  there  have  been  many  major 
engineering design changes that have affected many of the parts used in the AXOD transaxle.  This version of 
the AXOD  "Update  Handbook"  begins  with  the  1986  model  year  and  will  explain  each  change,  the  parts 
affected by the change, and any parts interchange problems created by the change.  This booklet is an updated 
version of the original.

  This updated version of the AXOD "Update Handbook" will also cover the changes that occured in the 1991 
model year, when electronic controls were adapted to the AXOD transaxle, making it an AXODE, and now 
called an AX4S transaxle.  We have included the changes on the AX4S transaxle up through and including 
model year 2002.

  We wish to thank Ford Motor Company for the information and illustrations that have made this possible.
