TITLE: External Filters on Reman ATM Units
APPLIES TO: Optima
SERVICE TIP:
KMA has received questions regarding external fluid filters on remanufactured Optima automatic transmissions. ATM units installed in
early-production 2001 MY Optima models (10/1/2000 - 12/31/2001) were equipped with an external fluid filter. Beginning in January 2001, the
external fluid filter was phased out. Because both types of cores (with and without external filter) are entering the remanufacturing process, dealers
may receive either type of unit when ordering any of the remanufactured units listed in the table below. Please note that the table lists two different
part numbers for each engine size, based on production date. These part numbers are not interchangeable, due to internal differences that are not
related to the external fluid filter. There are no functional differences or issues of compatibility between ATM units, based solely on whether or not
they are equipped with an external fluid filter.
