transmission fluid ????

[rodo]

Yesterday, when fixing the trans fluid temp sensor, the parts person at the Ford Dealership gave me Mercon LV fluid instead of Mercon SP. I did not realize it until this morning (after I have put it in and drove it about 100 miles). What do I need to do?? Drain and refill with SP? Will this hurt my tranny?

Ok...after doing a little searching on the internet, it looks as if the LV replaced the SP:

TECH TIPS TO THE FORD DEALERS

Approval to Service ALL 5R110 Automatic Transmissions with MERCON® LV
Beginning immediately ALL (2003 to 2010 MY) 5R110 automatic transmissions can be serviced with
MERCON® LV automatic transmission fluid in place of MERCON® SP.
Initially only the 2009/10MY 5R110 automatic transmissions were filled and serviced with MERCON® LV.
In an effort to reduce complexity, Ford Motor Company is allowing all previous model year 5R110
automatic transmissions to be serviced with MERCON® LV automatic transmission fluid. This pertains to
top off as well as fluid replacement. Mixing of MERCON® LV and MERCON® SP in the 5R110
transmission is acceptable. Extensive testing has been performed to insure there are no functional or
durability concerns with the use of MERCON® LV in the 5R110 automatic transmission.
Vehicles affected are F-Series Super Duty trucks (including chassis cab, motorhome, LCF).

Interesting, i knew they changed the fluid but i bought my truck used and was curious as to which fluid to top it off with since i didnt know what was in there. I now know i they can be mixed, thanks
