I recently noticed that when coasting or breaking is followed by acceleration (seems to be only when the car is moving between 25 and 40 mph) that there is a slight jerk. After recreating the problem a few times I noticed that the rpms jump up to just a little over 2000 then after the jerk it drops back to 1000-1500 which is usually normal. While it hasn't happened every time these conditions are replicated, it has been fairly constant. Hoping that it would be an easy fix, I just had the transmission fluid flushed. The car is at a little over 100k miles. Transmission is automatic. Any thoughts on what the trouble might be?
Observations that I haven't been able to confirm yet: It seems like the problem occurs less going uphill (haven't tried recreating the problem going down hill); It also seems like the longer periods of driving (15+ minutes) result in less occurrences though I'm not certain of this either yet.
UPDATE: I have noticed that when I take my foot off the gas between 25-35 miles per hour the RPMs drop down to just over 500. At any other speed it remains over 1000. If I begin accelerating before the RPMs drop below 1000 at the speeds where I'm having this issue it doesn't seem to jerk but if I let it drop below 1000 it does. Does this change the circumstances at all?
