Hi, I have a 98 Honda accord automatic the car drive good, but if I try to speed the car will not change into 4th gear, it would just over rave, also when the car is in a stand position and I try to move the gear shifter back and forth to park and back to reverse or drive after a while the car would give a jumping jerk, and idea this happen?

Consider changing the transmission fluid and replacing the Vehicle Speed Sensor (VSS). Also, check for a faulty automatic transmission gear position switch:

Automatic Transmission Gear Position Switch Replacement

1. Remove console and disconnect 14-P connector from switch.
2. Remove both console switch mounting nuts.
3. Position switch slider to "Neutral."
4. Move shift lever to "Neutral," then slip switch into position.
5. Attach switch with both nuts.
6. Test switch in Park and Neutral positions of shift lever. Engine should start, when shift lever is in Neutral (anywhere in the range of free play).
7. Connect 14-P connector, clamp harness, and install console.

I recently replace the transmission, so I know it's not the fuel, but I will try to replace the speed sensor, thanks
