Best Transmission oil

[Richie]

What is the best transmission oil to use on a 2011 Canyon Star Ford F53 V10 F450? The transmission is the 5r110w transmission, I think.
Thanks for any help.

The only oil to use is Mercon SP. At least that is what my 2008 manual says. It also says Mercon V can be used in the power steering. I bought a quart of each from Ford a couple of years ago, used a bit of the SP and none of the V.

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).
Motorcraft MERCON® LV is now available in three sizes:
Part Number XT-10-QLVC -- 1 quart
Part Number XT-10-DLV -- 55 gallon drum
Part Number XT-10-BLV -- Bulk
Further information can be found in the on-line Automatic Transmission Fluid Chart or SSM #21114, accessible from the PTS Home
Page. .

Thanks for that update, Pirate Ford has introduced the successor to SP and it is good to know I can mix it. The OP's chassis should be 2010 or 2011 depending on when he bought it so he should use only the LV.
