98 Civic DX Automatic Transmission Problem?

[Spurr]

I have a 98 Civic DX, automatic and recently I have been noticing what appears to be strange shifting. For instance, when I roll up to an intersection and the light turns green before I stop or when I make a slow speed turn (into a driveway for instance) and then get back on the gas, the transmission shifts down with a bit of a clunk (nothing too loud, just abrupt/rough). Also, when coming off the highway onto a ramp (and on the brakes) the car seems to be abrupt/rough when it downshifts (from 4th to 3rd).

Does this sound like a fatal transmission problem or might it be an issue as simple as new honda tranny fluid? Any suggestions? Thank you for your assistance.

when was ATF fluid changed out?
check if fluild is low.
might try changing out fluid.
If fluid looks bad, may need to change out fluid a few times, you can drain only partial capacity of tranny, since some of the fluid in torque converter can not be drained. you will have to run engine to flow new fluid thru converter and rest of tranny. Use the honda fluid from dealer. Also Throttle Position Sensor may be bad, causing bad shifting.
