Why is transmission jumping at lower speed
Car runs good on hi speed jumps on lower speeds
Another thing to check is the fuel pump. I just replaced a fuel pump that would not deliver a constant fuel supply under heavy load but when the van was up to cruising speed it worked fine . The pump couldn't produce the pressure necessary for acceleration and gave a jerky takeoff at low speeds(higher rpm) but smothed out at higher speeds(lower rpm) when it didn't require as much fuel . Check the pressure on the fuel rail when the van is not running. Turn on the ignition and listen for the pump to hum and the pressure should be around 40-50 lbs. When the van is running it should have around 35lb. This video is a good explanation of how it works and how to check and diagnose the pump .Hope this helps
addienickh , Check your transmission fluid level and top up if needed. This problem may be transmission or engine related. May not be a true transmission problem but possibly a pressure sensor, electrical i.e. engine misfire or something else. Best to have vehicle scanned for diagnostic/error codes as this could pin point the problem. I have read some forums that state the EGR was an issue on the 1999-02 and some 03's Odyssey's recall I believe and may cause sputter and jerking. Some of the auto parts suppliers offer free code reading like Pepboys, Nappa, Advanced auto parts,etc and some of the guys are very knowledgeable and may have seen the issue often and put you on the right track. If no luck here pop into a good local transmission shop and have them take a look, diagnose and estimate repair. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
