'03 gets the revised transmission. Much more reliable but still owners of '03-'05 models have had issues posted on the web.
If the "jerk" you feel is at 35 MPH when decelerating and engine RPM is below 1000 it's just the trans down shifting. (assuming it's not a violent down shift) You can watch the tach bump up slightly under these conditions. If your engine speed is above 1000 RPM when decelerating you shouldn't feel the down shift or see the RPM increase..

All the MDX, from 01-06 have the same basic 5 speed transmission. This is the transmission shared with the 2nd gen odyssey, and 6th gen accord. All these cars suffer some sort of transmission problem. I am wondering though, that in 2003, that revised transmission (as skoobahead1 said) really made a significant difference, because, I saw that lots of 03 owners also have the tranny problem. But the 04,05,&06 have very limited amounts of problems with the tranny, according to users. This really doesn't make sense to me, especially because the tranny in 03, 04, 05, & 06 are same. The only difference from the latter models is a revised exhaust. Does someone know more about this? I am really confused

whoops, also, the honda accord isn't sixth gen, it is the seventh gen that has the prob, because it is the one that has the 5 speed automatic. The 6th gen has the 4 speed automatic

It just seems to me that I shouldn't be able to feel the downshift, no matter what the RPM. The tach doesn't bump either. I am so frustrated with this whole thing - I have a new transmission!!!

3rd Tranny, 88000 miles by consultken

We haven't heard yet if Acura will step up and cover us. The first transmission on our 02 MDX went out at 35000 miles in 2004. Acura handled that with alacrity. Now, the replacement transmission is bad at 88000 miles. So, with less than 90000 miles, we are to have transmission #3.
 
Consumer Reports still speaks glowingly about the MDX, I don't see how.
 
CR trashes the Dodge Grand Caravan, but I just sold my hoopti 1996 Grand Caravan with 206000 miles and it never needed transmission work. What are they smoking at Consumer Reports?
 
I sure hope Acura does step forward since this is obviously a chronic and ubiquitous problem.
 
I also cannot recommend the MDX to anyone who keeps a car more than 3 years. I guess we'll look at Jeep next time since they have a lifetime powertrain warranty.

jkotlar,
 
My downshift on my '05 is very suttle at 35MPH when the engine speed is below 1000 RPM. The tach jumps up maybe 300 rpm..This is the only time I feel a downshift. If my engine speed is above 1000 RPM I feel nothing and the tach does not move while decelerating through 35MPH.
When is your "rough' downshift happening? What speed and what engine RPM?

That is exactly what I feel and exactly the same RPM and speed (30-35mph). I don't know if I'd consider it "subtle," though.. the car jerks a little. I can definitely feel it. Have you taken yours to the dealership?

A 300 RPM downshift increase under those conditions is not a transmission problem.The transmission is downshifting. Its completely normal for this vehicle. It's not a CVT. I can't speak for your MDX but my downshift is subtle. A harsh downshift would cause your RPM increase to be much higher. If another owner has one that doesn't have this downshift characteristic please chime in. I'd be surprised.

My only issue with that is that the dealership apparently is unaware that this is a normal thing with the MDX. They said that the tech was able to duplicate the problem - and the first time I had it in the shop, they replaced the transmission! The car has less than 50k miles on it!

If the 300 RPM "bump" happened on your original transmission and it happens on your rebuilt it sure seems more than coincidental.Perhaps other MDX owners will chime in with what their vehicle does in the same situation. If I were you and had spent all this time on this issue I think I would ask your dealership to drive another '05 MDX on their lot and see for sure. Keep us posted as it sure is a tough decision to keep this nice vehicle past it's warranty if we have to shell out $4500.00 for transmission work.
