    I have 98k miles on our Quest. Until this year, we haven’t had any problems with our Quest for about 5 years. Earlier this Summer the dealer found that both motor mounts were failing/broke. They say that is a common issue. So, while doing that work, at 91k miles, I also had them flush the transmission and change the spark plugs.

    This weekend while on a trip, we noticed when the transmission shifted from 4th to 5th it made an odd thump. It didn’t do it all the time during the trip. It seemed to do it more under light throttle and always on the interstate.

    Any ideas? Should I have the dealer flush the transmission again? I’m wondering if maybe the last flush dislodged some fluid buildup/sludge that is now blocking a passageway…

    Thanks,
    Mark

    i have talked to a transmission specialist and he said changing transmission fluid can often times create more problems then just leaving it alone.
    Hope that’s not the case for your issue.

    I disagree completely. If you use the proper transmission fluid, your transmission will be happy. The problem is when the new transmission fluid is not the correct one. Every time a transmission fluid is changed, not 100% of the old fluid is extracted. There is always remaining fluid in the torque converter. Incorrect fluid is more likely to be incompatible with the old fluid that remains in the converter. That will create shifting issues.

    Saying that replacing fluid will create more problems is equivalent to say that replacing engine oil will create problems in the engine. Again, if low quality oil is used in the engine or if not replaced on time, it will create sludge inside the engine causing poor lubrication, then more friction, then premature damage.

    It is the low quality oil/fluid that will create problems, not replacing the oil action.

    Always use high quality oil and will car will give you lots of miles.

    My ’99 Quest is 167K miles and running like new.

    If the fluid was changed by the dealer and you feel your van is having issues because of it, take it back to the dealer and talk to your service advisor. Nissan dealers give some warranty on their jobs. Talk to the advisor about a warranty check on their previous work.

    Just an update…about a month after this post, the transmission seemed to clear itself up. We have had no further transmission issues. Now at 114k miles.
