Thats exactly what i was thinking. Naturally aspirated vehicles lose alot of power as you climb in altitude. Just slap a supercharger on and you wont have to worry anymore lol.

 

What ever you do dont say this in the tow-haul forum.

 

You can get most of it out by draining the pan and TC.

 

Well, time consuming and very aggravating.

 

drained the pan, removed it, then drained the converter.

 

That's how much came from the pan , yea the rest came from the converter - I flushed the the lines and cooler seperatly on this one.

 

I think it does an excellent job towing. However I do have to say our 2003 Expedition with it's revised rear suspension does an even better job. Less trailer induced sway by far. Never checked out the tow-haul forum, guess I should stay out of there. I would never have imagined that I still have no major problems with this F-150, not even changed a spark plug yet. Lots to say about technology change from just a few years ago. This truck has worked HARD.

It is quite a far cry from my 69 nova hotrod with a 68 SS camaro 327 engine (basically the 5.4L GM of yesteryear). However, I doubt that the 5.4 motor will last 39 YEARS and not use a drop of oil and idle so smooth that a glass of water does not even shake on it.

 

Hey Boomer,
I was just referring to you towing 7000lb travel trailer. Everyone in the towhaul forum thinks you need a powerstroke to pull that kind of weight and they will say your crazy. But I like to work my truck too. Ive got 170000 miles on her and she hasn't limped yet. There is something to be said about regular fluid changes, and good driving habits.
