Thanks to all of you for the valuable information. At least now I have some options to explore and hopefully save my truck. I will keep you posted when I find out what the problem turns out to be.

Coil and plug. Sounds like it's misfiring to me.

Coil part no. 3L3Z-12029-BA
Plug SP-515

I work at a Ford dealer. My 2005 did it all the time.

The ticking is the phasers and solenoids. Mine started ticking like a diesel around 150,000 mi. When I finally got rid of the truck with 215,000, it still ticked. Phasers are very costly. To do the job correctly, you'll need:

2 Phasers
2 Solenoids
2 Valve cover gaskets
Front cover gaskets
Preferrably..timing chain tensioners and guides. Shouldn't need chains...unless they stretched.

Let me know if you need prices and part numbers.

Thanks for your help. I have already experienced that ticking noise your talking about. I can live with that as long as its not hurting the engine. The shaking and shuddering seems like serious problem that could possibly lead to permanent damage. I wouldn't mind replacing the coils and plugs and even the transmission fluid if that will take care of the problem.

When I towed with F150 I never allowed over drive even on flat ground, and never had a problem. I only used "drive" in town and used manual 5th as highest gear.

I would think you would get a check engine light if you had a misfiring situation, no matter coil or plug. That's an easy catch or a computer.

If it were me I would change the tranmission fluid. screens and fliters and inspect the old fluid for everything from overheating to debries.

I think this is the best answer. Ford has been through several transmission fluids over the past 10-15 years. They went from mercon, to mercon V, to mercon sp (only available from a ford dealership), and now have mercon LV as an option. Other than transmissions calling for mercon SP, I use Valvoline maxlife ATF in all my ford transmissions, with no issues. Depending on they year of your truck and transmission type, if a transmission service was done and the wrong fluid was put into the trans mission, you could be experiencing problems (shuttering and downshifting issues) from it. The best thing to do IMO is change the transmission filter and then have the transmission flushed with the correct fluid (which should be identified on the dipstick itself). Give it a few hundred miles to see if the problem went away.

I'm not saying a coil couldn't be giving you a hard time once good and warm, but more than likely it would throw the engine light on if it were not functioning correctly and you would notice performance issues (lack of power) upon acceleration.
