I have seen torque converter shudder around that speed but only when going into lock up seems to me maybe ignition break down such as coil or coils going bad i have done a lot of those.there is more of a load on them the higher the gear such as 40 and up. good luck!

Sounds like a bad spark plug, spark plug wire. Probably the spark plug wire. They usually act that way when load is applied. It may misfire under light load and not at idle. Try plugs and wires.

Do you have an eight cylinder? Does the noise go away when driving past 40 MPH? If so it is the torque converter.

Engine sputters between 40 to 60 mph


Do you have a check engine light? You do not have an external gas filter, so it may be associated to your internal fuel pump.

Your description sounds more like a torque converter clutch problem. It would explain the poor mileage, having to floor it to go. I suggest having the transmission scanned, looking at the slip speed of the torque converter clutch.

Boss has 2005 Yukon, says speedometer shows random numbers (ie, 40 mph while stopped or 40 mph when doing 60. Intermittent problem sometimes fine.) Any helpful hints appreciated.


The speedo in electronic and can have various circuit board problems. I've had to cars with erratic speedos and in both cases the dealer said replace them and big buck bills. I found a shop that repairs them and charges $100 buck and free shipping back. About a 4 day turnaround.

97 concorde with 3.5 engine @ 40 to 45 mph it starts bucking .


Computer firmware needs upgrade

Take your car to a Chrysler dealer shop and have them update the transmission program.As your tranny wears it loses it shift point and stutters between 40 - 45 mph looking for the right gear to change to..Had same problem in 94 Concorde and 94 T&C minivan.Reprogramming tranny fixed both cars.
