Replying to: pcruciani (Feb 23, 2007 4:53 pm) The hesitation/bucking is definitely more noticeable at slow speeds, particularly when decelerating.   My wife drives an 07 EX-L with same problem. At first, I also thought it was the VCM, but then I took it for an extended test drive. I noticed that when it does hesitate on deceleration the RPM goes up from 1000 to 1500. To me it seems that the transmission is downshifting whenever the van is coasting.   The van has a little over 1000 miles on it now, and seems like it doesn’t do it as much anymore, or if it does, it does it much smother now.

Replying to: exb0 (Mar 19, 2007 6:39 am) Are you sure it isn't the transmission working to slow the van down? These vans don't coast down hills like older vehicles do and the transmission works more to slow the van down so you're not using your brakes as much and wearing them out. My EX does this and it took a while to get used to, but I like it now. I don't have to hit the brakes as quickly or as hard to slow down.

Replying to: bobber1 (Mar 19, 2007 4:40 pm) When slowing down, I can definitely feel the transmission downshifting, but it is rather harsh/abrupt (rocks you forward in your seat). Is the downshifting in your's harsh (very pronounced/noticeable) or smooth (slightly pronounced/noticeable)? Replies to this message: deewof (Apr 03, 2007 8:40 am)

Replying to: pcruciani (Mar 30, 2007 6:46 am) Harsh might be too strong a word in my case, but I have a similar downshifting problem in my '06 Accord EX w/6 cyl. engine, with 7300 miles. It's making a huge dent in my mpg, due to the numerous times a day I need to press the accelerator just to maintain normal speed, which would not be needed were it not for the frequent downshifts on perfectly level terrain anytime I slow down even slightly. After observing the frustrating comments of other Honda owners on these forums, the cause appears to be what Honda engineers call " Grade Logic Control ". It's supposedly hi tech stuff more advanced than curved hockey sticks when all the right signals are emitted. But when there's gremlins & glitches, we pay a pretty hefty price for faulty technology.

Replying to: pcruciani (Feb 21, 2007 6:19 pm) I just bought a new 2007 Odyssey EX and have the same issue, but do not (should not) have VCM. As you mention in later posts, it is very noticeable at lower speeds while decelerating. I actually move forward at each downshift. I do not feel anything in the gas pedal. I am getting ready to call the dealer for an appointment, any suggestions?

#14 of 35 2007 Tranny by nowakj66 Apr 04, 2007 (10:37 am)
My 2006 Ody Touring is very smooth shifting. My friend has a 2007 and she has complained of the roughness of the tranny in her 2007 as well. She also complained of a buzzing that occured about 30 mph. In the end, the dealer replaced the transmission and it has improved.   The tranny was redesigned in 2007 to be sturdier but it seems smoothness has suffered.

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.
