I have ran my truck like this for at least 2 months now, and it does seem to be getting better with the tc, however, it's still not all there. I have yet to get anything fixed at the shop but when I do I will let you know. It's taking me a while to get it fixed cuz its my only source of transportation. Oh, and I believe you have to have at least 3 misfires for the CEL to show, but idk. I will let ya know if I get anymore info on this problem

 

I took my truck in yesterday and they found #4 misfire. They performed a maintenance tune up, Replace plugs and coils and the problem is GONE!

 

Awesome, even with the TC? How much did it cost if you dont mind me asking

 

Plugs and coils at the dealer is a small fortune. I'm guessing close to $1000.

 

I spray my engine with water to get the dust / crap off when I wash my truck.

Thanks,

Not a good idea.

 

Started about 8-10 months ago... Shuddering when TC unlocking when accelerating at 40-50 mph (low RPM's < 1800-1900). Trans fluid was dark, but did not smell burned. Had fluid changed and friction modifier added. Shifted PERFECT!

Now 8 months and about 8000 miles later, it has restarted its shuddering. Same symptoms. Fluid is dark again.

No CEL. I've had a COP go bad and this doesn't feel the same. 91K miles on the truck. Original plugs and coils.

Trans shop wants approx. $1850 to rebuild, includes a new TC.
The mechanic that changed the fluid / filter recommends getting a reman. trans from Ford with 10 yr. / 100K warranty. Its approx. $2450 plus $500 to swap out.

HELP! Any ideas. Rebuild or reman. tranny from Ford?

Thanks!

 

Reman from Ford with the warranty if you plan on keeping the truck.

 

@skkzh_g: if you have 91k miles on original plugs and coils, chances are you have having a lot more misfire problems. A LOT of posters here have thought it was a transmission problem and 99% of the problems are plugs or coils. Before digging into the transmission, replace the plugs and boots, coils if necessary. Statistically you are far, far more likely to fix the problem than your transmission. Of course your tranny shop wants to replace the transmission.

 

It could be a misfire but I have not seen any evidence in a CEL. Plus fluid in tranny is dark again.

I know it is due for plugs and boots. Should I change the coils if there isn't a CEL or rough idle? I had a coil go bad before and this shudder isn't comparable.

 

A low grade misfire will not trip a CEL. I would change the plugs and boots to start with, at 91k and 13+ years they are due. However, if the tranny fluid is dark it may be on its way out. When the fluid was changed, was a complete exchange done or was it just a pan drop?

 

Like GLC said, Plugs and boots for sure. It very well might save you the cost of a transmission. I have read many posts over the years where people are convinced its the torque converter or transmission and everything clears up with the ignition system tune up.

 

@GLC - Pan drop and filter. Will do plugs and boots to start with. I've ready many different posts here about various boots, suppliers, etc...

Recommendations for the boots and plugs for the '02 4.6L?

 

Motorcraft plugs.

 

Absolutely Motorcraft plugs.
