You described my scenario perfectly and it makes sense. The more I think about it it seems like maybe it's between gears when it happens. It's just really annoying and a very unfamiliar sound to me. I've had many automobiles in my time and none of them did that like this Expedition does.andy, did yours come with hankooks are some other tire brand? ours has hankook.
thanks
my 13 f150, would do this periodically
the expy so far has not done it to the point of standing out.
but a part of the logic in the tranny, brains does disengage the torque converter near the 2 to 1 down shift when speeds are low, as in 5mph, as explained to me a few years back.
its similar to my engine brake on the motorhome, down at 10mph it will disengage and you roll free as it were, if you add throttle it will clunk as the 1200 ft lb of tq brings the bus back in motion
at a rolling stop..which is illegal , i think the vehicle is doing the free wheel action, then if you mash the gas it has to re-engage and maybe this is the clunk as it is deciding which gear to to select.
i have noticed my tranny will not go through every gear all the time. i have seen 1 to 3 upshifts and 3 to 5 a few times, if i am accelerating on a downward slope.
I got the Hankook Dynapro HT on mine. Seem like decent tires. I just put a set of the Pirelli Scorpions on my wife's MDX and really like them. Seem to wear good and much quieter than the Michelines she had on there beforeThanks Andy
i like my hankooks, funny, as all my rides are riding on them. The motorhome has hankooks.
the ones on the expy seem so be wearing really well.
the bridgestones on the 13 f150 were really worn bad at 29999 miles, when i traded it .
i was worried the expy would come with the scorpions, i had them on the 2010 f150 and they wore out FAST. i had seen a few expys with the scorpions and bridgestones. was surprised to find the hankooks on the vehicle we bought
