Hello fellas,
just today my expy started making a strange humming and vibration when in iddle and in Drive. and only when cold. it goes away after completely warmed up. Could it be the fluid?

also how is the trannys on these babys?
are they pretty good or weak trannys?
i have an 04.

thanks in advance for any info.

Could be a number of things. PCV could be getting clogged, thick oil not getting to the top-end of the motor, idler bearing going bad, bad fuel injector, or clogged cats. Sometimes the air filter housing, esp. aftermarket filters/intakes, can make a humming or whistle sound, but not sure if that would equate to a vibration. How bad is the vibration...is the engine shaking, is the drivetrain shaking, or is it a rattle?
Trannys are fairly stout as they are designed with towing in mind. But as any other item on a car can go bad without warning. Keeping up with the maintenance is the most important thing. If that's done, it could last a long time.

could be air suspension youre hearing...do you have air susp?

nope no air suspention.

i was thinking more along the lines of my tranny or converter.
Cause it only does it in Drive and stopped.. if i put it in netral or is i let go of the breaks and move it, goes away.

thanks for the help guys.
Im going to flush the tranny, change the filter and see what happens. Maybe non-melcron V has made its way into my tranny some where along the line. and this is some form of shutter Ford was trying to aviod with melcron V.
