Replying to: nowakj66 (Apr 04, 2007 10:37 am) Did your friend with the 2007 experience any "transmission slipping" sensation and/or harsh/abrupt downshifting as well? How many visits to the dealer before they agreed to replace the transmission?

Replying to: ml111 (Apr 04, 2007 12:08 am) Definitely take it in. I can't believe that is "normal" performance for any car, especially a Honda.

Replying to: ml111 (Apr 04, 2007 12:08 am) My wife and I just bought a 2007. I drove it for the first time today since the test drive.   I'm noticing the exact same issues, at lower speeds. Seems somewhat to happen at the same time as the VCM engaging and disengaging. But have also noticed the RPM slight jump and drop also. It's annoying as heck to me at slower speeds. That said, my wife doesn't notice it and she drives it 95% of the time. Might watch it for a bit as the car has 800 miles now.   Would love to hear if someone else discovers a definite problem or solution. Replies to this message: nowakj66 (Apr 17, 2007 6:43 am)

Replying to: dougp (Apr 07, 2007 6:15 pm) I am not sure how many times my friend took her '07 in before they replaced the tranny.   She did say the ECO light flashed so much that she finally put a black piece of tape over that part of the dash display.   The ECO light in our '06 comes on every so often but not in a "strobing fashion" as she described. I just assumed she was overly sensitive to it.   My Accord Hybrid also has a (well behaved) ECO light as well.   I would have to have some experience in an 07 Ody to tell you if behaves differently than our 06.

And I have not experienced the symptoms.   I read that 2000 rpms translate to 60mph but mine does 1800rpms at 60. Did they change gearing for 07?   Why are the valves closed when the cylinder is deactivated? Wouldn't open valves cause less resistance since there is no compression or vac? Or does air drag cause more friction than comp. & vac? Just curious.   Don Replies to this message: thegraduate (Apr 28, 2007 4:01 pm) blackexv6 (Apr 29, 2007 2:55 am)

Replying to: ml111 (Apr 04, 2007 12:08 am) This is an update from my first post #13. I took the van back to the dealership and said "harsh movement" at each downshift while decelerating/coasting especially at lower speeds (40mph and down). The technicians did a diagnostic test and test drove it as well. They came back with "everything is normal". I can't believe that this is normal. I have never driven a car like this including all the rentals I've had on business trips. To continue, I also test drove another van, the same model, from the lot and it was much smoother. I ran out of time at the dealer so my next step is to go with a technician in my van to demonstrate what I'm talking about. (In hindsight I should have done that the first time.)

Replying to: pcruciani (Feb 21, 2007 6:19 pm) Took the vehicle to the dealer for a third time for the hesitation/bucking, harsh downshifting, and Navigation system issues. Nothing was fixed.

Replying to: ml111 (Apr 22, 2007 5:33 pm) Let me know how your test drive with the technician goes.

Replying to: andmoon (Apr 21, 2007 6:06 am) I read that 2000 rpms translate to 60mph but mine does 1800rpms at 60. Did they change gearing for 07?   My aunt's 2005 Odyssey runs between 1,700 RPM and 1,800 RPM at 60 MPH, so I think the initial info you got is a little off. My 4-cylinder Accord (2006, Automatic) runs at 2,000 RPM when going 60 MPH, but the engine is smaller and less torquey, meaning engineers tune the gearing differently to account for this. The Odyssey should run lower RPMs than my car, so I think 1,800 is normal, and that your van is no different than others.'

Did they change gearing for 07?   Yes, the '05/'06 Odyssey has a different transmission than the '07. The '07 Ody now shares the same transmission as the Pilot & Ridgeline (4 shaft design).   Also you are correct, the shift points are different.   '05/06 Odyssey: 60 mph = 2000 rpm '07 Odyssey: 60 mph = 1800 rpm   I'm not 100% sure if they changed the shift points to eliminate the dreaded droning defect found on all '05/06's or just to maximize efficiency of the drivetrain.
