MERCON« LV Service for 5R110W Automatic Transmissions Approved
Beginning immediately ALL previous 5R110W automatic transmissions (2003 to 2008 MY) can be serviced with MERCON« LV
automatic transmission fluid in place of MERCON« SP. This will result in significant complexity reduction for customers using 5R110W
automatic transmissions which can now all be serviced with MERCON« LV ATF (previously only 2009 /10 MY 5R110W automatic
transmissions were serviced with MERCON« LV). This pertains to topoff as well as fluid replacement. Mixing of MERCON« LV and
MERCON« SP in the 5R110W transmission is acceptable.
Extensive testing has been performed to ensure there are no functional or durability concerns with the use of MERCON« LV ATF in the
5R110W automatic transmission.
Vehicles affected are F-Series Super Duty trucks (including chassis cab) (2003-08), Excursion (2003-05), F-53 Motorhome (2006-08),
Low Cab Forward (2006-08) and E-Series (2004-08) with 5R110W automatic transmissions.
Note: Vehicles equipped with the 6R (2008 and prior) and 6HP26 automatic transmissions still must be serviced with MERCON« SP.
This includes V8 Explorer/Mountaineer (2006-08), Expedition (2006-08) and Navigator (2005-08).
