2003 MDX Tranny is going.....

Oh I mean it's going ....

Had couple incidents that when I put in D5, the car just wouldn't move at all. I need either put it back to P or shift it to lower gears and back to get engagement. Other than this, nothing seems wrong with the tranny.

The frequency of this seems going higher. Couple months ago it's like once per 2-3 months. Now it's like once per month or even higher.

Anyone knows what is the culprit? I would like to fix it asap. Thanks.

Ok, the tranny is acting up more and more frequently. Most of the time in the morning when first started.

I am just wondering if this has anything to do with the tranny filter. If it's clogged, will that casue the valve pressure drop and loose the ability to engage the clutch?

And it's still the same, if I put it into 1 or P and back to D, problem solved.

So, anyone got a solution already?

Tranny problem??

How many miles on the car? Has tranny fluid ever been changed? When was last change? You might try a 3 quart change with the new fluid from Honda (Cheaper at your Honda dealer, if you ask). If it continues it's time for a "professional" evaluation. Get back to us for additional assistance if needed, and good luck!

After more than one year, my X is still alive.

I visited the dealer I bought the car, but from the service manager to the service advisers all played idiot and claimed they never heard the tranny problem. And since the car is out warranty already, the dealer won't even give me a quote without "servicing" my car first. And I was told that the chance Acura will step up to help is slim.

I contacted Acura NA, but the customer rep also played idiot, claimed the she is not aware of this problem and told me to bring the car to dealer to confirm the problem. Then start from there. So if even the Acura NA doesn't know about the problem, how could I trust their dealer???

Ok, fine. I visited couple tranny shops, almost all of them told me what could be wrong, and they all said it's a famous problem for MDX. One shop told me they have fixed hundreds of MDX. The price, from $2500 to $4000.

I did some research and pin pointed the failed component. The slippage happened couple time per day when when it was at the worst time. I was getting ready to tear the tranny apart to replace the sprag.

But, for some reason, the tranny gradually heals itself. Now the slippage rarely happens.

Since I know what it takes to fix the problem, I am not too worry about it and I will keep an eye on it. I know I probably will have do it someday.

So you're saying to fix the problem you do nothing? Kind of confused as to what you actually did. Did you change the fluid at all?

So they "played idiot" because they didn't experience a problem that you claim "rarely happens"?

On an eight-year-old car that's been out of warranty for at least four years, did you expect otherwise?

They're all probably thinking of the tranny problem that afflicted the 2001-2002 MDX, not the 2003.

That's a good question. The whole reason for changing the fluid is to prevent problems. Don't do it, and you're asking for trouble. Interesting that this question still hasn't been answered...

Proman,

Thanx for sharing ur experience. Damn, u should let us know ur experience earlier.

My X got the trans problem u described 2 year ago. I am pretty handy but have no experience with the AT and don't have time time to dig in deep like you. So I took it to a dealer, yep, the SA first denied there exists or he ever heard of any known issues for the trans. The mechanic later told me it's probably the clutch, just like u said. But the dealer is not allowed to repair it, they can only replace the whole thing.

The car was way out of warranty, and I performed most of the maintenance and repairs by myself, so I think Acura won't even consider making a case for me. So I would like to take the car to some indy shops. But I got lucky, Acura agreed to cover the parts and 50% labor. I know some other people got denied with any coverage, and some got more or less covered, like me. I believe Acura considers this kind of issues case by case. Don't know what's their criteria.

Not sure if u tried to replace the trans fluid. DON'T DO THAT!!! It has nothing to do with this problem. In fact, this was what the dealer did first, only made the situation much worse. Before, the problem was only intermittent. After the fluid change, the car just wouldn't take off at all. I am not sure why, I think the new fluid has better lubrication ability and makes the clutch slips all the time.

Good luck with ur X and please keep us updated.

Wow, that post is virtually unreadable. mdxers is an internet forum where you ought to be posting in English, not a place for cellphone texting abbreviations. This post sounds like my eight-year-old niece texting with her classmates in the third grade!

Thanks Rich.

I know it has nothing to do with the tranny oil, though it's always people's first response. I just would like to see if I can find someone here with some real experiences and know what is really going on. And can offer me some professional opinions on taking the tranny apart.

I did dig deep to find the actual part that failed, not just the assy. The replacement part is only about $16. But you need to tear the tranny apart, and down to the earth especially for the 1st clutch. I don't think anyone here ever did that, but just hope. That's the purpose of this forum.

I heard many different stories on Acura coverage on out of warranty vehicles. That's why I talked to the dealer. But I wasn't as lucky as you. I also did all the maintenance myself, why Acura covers you but not me?????

New tranny oil makes the situation worse. Hmm, that's a good point. Never thought about that. But it's a good reasoning. Next time when I replace the tranny oil, I will keep an eye on it to see if the problem comes back.

Proman, did any CEL codes come up over the years ? Usually that's a harbinger of (bad) things to come.

My former vehicle was a 2001 Odyssey that experienced transmission problems after 11 years... but they eventually manifested in both slipping and check-engine-light warnings...

Unfortunately most dealers and shops I went to claimed they'd have to tear apart the AT to determine 100% what the fault is -- the good news was it imminently fixable - the bad news it was between $3000 and $4000... secondary bad news was no one could guarantee I wouldn't be stranded with a AT that wouldn't go into gear - sounds like you've been lucky on that account...

If u ended up with actually tearing it down (I really hope u don't have to), will u please take some photos or video tape it and share with us? I read ur other posts, looks like u really know cars. Ur opinions are cut right into the point and u can do very difficult repair, but u don't post a lot.

The MDX trans problem is so famous but available in-depth info is so rare. If u can let us pick ur brain more often or post more info, that would help us a lot. TIA.

Leaffan, no CEL ever comes on. I think there is no error code for that kind of problem. I took my X to couple shops that can fix it, they all wanted 3000 - 4500. I was told they are going to do an "upgrade" on my X, but wouldn't tell me the details about the "upgrade".

So after I researched myself, I know what is going on and I know what it takes to go around it or repair it. So I have peace in mind and didn't have time to do the repair.

And, as I mentioned, the problem rarely happens lately, it looks like the tranny is healing itself. Maybe it's what Richkuan said, the fluid got old and the lubrication capability is not so good and the slip doesn't happen easily.

Rich, thanks for your compliment. You yourself is an expert too. But looks like you didn't post for a looong time. We will benefit from your knowledge too.
