Just a drop and fill?LV is just the name ford gave the fluid spec that they use.
No, personally I would keep an eye on the condition of the fluid and change it accordingly, maybe 60k or so depending on how hard you drive.
Anyway to guarantee its a newer machine? I just hear the horror stories of people getting their tranny flushed and having horrible issues.I would get a flush done, that way it cleans the whole system, just dropping the pan you skip the torque converter.
As long as its a newer machine they work great, and they also clean out the trans cooler too witch is nice.
