when im driving and it changes into the overdrive gear it will shutter and
gitter, sometimes bad sometimes almost no at all. its a 5.4 auto 4x4 and i cant figure it out.


thanks

 

What year, how many miles, has the fluid ever been changed, have the sparkplugs and coils ever been changed?

This may be a low grade engine misfire, not a tranny problem.

 

its a 2000 with 79k and its also the 7700 series. i bought it recently so the dealership changed all the fluids in the truck and im not sure about the spark plugs. o and by the way what are the coils you mentioned?

thanks

 

The ignition coils that are on top of each spark plug, you don't have a distributor or coil packs or spark plug wires. At 79k, if the spark plugs have never been changed, it's about time to do it. Did the truck come with any kind of warranty?

 

yea it does but the dealership is over 100miles from my house so if it was something simple like a filter i would just do it my self.

 

I doubt it's that simple.

 

My bet is a low grade misfire. These guys have you on the right track.

well if anyone still cares i took my truck to a transmission place and they said that it is a low grade misfire. then they said i need to change the spark plugs and boots. does this sound right?

thanks for the replies

 

Pack a lunch. Make that 100 mile drive and take advantage of your warranty.

 

Yes it does.
