Popping Noise
 

I have a 2005 Ford Excursion Diesel, and everytime it goes from first to second gear there is a distinct popping noise. I can feel it under my left foot as I drive. I know that this is a common problem on Fords...but when I take it to the dealership, they never seem to know what to do? Any suggestions as to what this problem is? It is driving me crazy. Thank you-

Sure its not the 2-3 upshift?

That might be right....read that it may be the sway bar?

Try and pay special attention to how many gear changes occur before you hear the 'pop' or clunk.. If it occurs between/during the 2-3 upshift, is concidered a normal function for the 5R110.. Not only on my own, but every 5R I've driven has had the clunk/pop to some degree if you pay 'enough' attention to the shifts.. Some worse then others (like mine) but will usually quiet after 3-4 sets of shifts as the unit heats up or with extended driving... May have a pattern, or re occur after a short 'sit time' with the engine off as well.. More so if the units cools.. Sometimes mine will pop/clunk after a 'set or two' of completed shifts after a trip on the highway.. Usually as mine,, the clunk seems to come from the floor area, but may have a bit of a 'bump' that accompanies the pop/clunk..

Some 5R100's have a clunk/pop on a roll away or launch (usually for R to D) at 2-3MPH.. Also concidered a noraml function....
