Hi everyone, I am new to the board but not to Ford Trucks
I am wondering if anyone might have a suggestion to helo toruble shoot an issue I am having. Here goes
Last year I was getting what felt like a tranny slip when accelerating from 50mph. too the truck to the dealer and they said it was a torque converter issue. So they re built the entire tranny for good measure and returned the truck to me. The same day I got it back it did the same thing. I took it back and they said sorry must be the plugs. I had all them changed and for the past several months all has been running well. ( except for the loud cam phasers that is) now at highway speeds 55 to 60 MPH when i let off the gas and then accelerate I get what feels like a miss, or a slip. I am leary about takingit back to the dealer without some suggestions or past issues that others have had so I can make some suggestions.

Thanks to all that post a response.

Is the overdrive on? If so, it's normal for some slight lag in accelleration; the overdrive kicks off and the truck launches in third gear.

Try disabling the overdrive.

 

How many miles on truck?

 

Thanks for the suggestion, I tried switching the OD on and off and still had the same results. The Truck has 100,000 miles on it.

Thanks

I'd have the transmission checked by a qualified shop. If it's never had any maintenance (I.E. fluid changes), it's most likely on its way to permanient failure.

 

Thanks to all that replied, it turns out it was a bad coil. a couple hundred later at the dealer and the truck seems to be running great!
