So the girlfriend just bought a 04' TL base 5AT with 150K, had incredible service records (one owner) every single service had been done (timing belt, water pump, brake fluid, coolant, power steering etc. etc.) except for the transmission, only been serviced once (of course the weakest link). When shifting into 3rd at low RPM's the tranny would shutter and when it shifted out of 3rd into 4th it would also shutter.

So I work at a Honda dealer and did the tranny drain and fill 3 times *With Honda z1* along with a new filter and completely fixed the issue, just shows how much changing the fluid will help. I'll probably continue changing the fluid every oil change considering it only costs me about $12.

 

refilled it with Honda z1?

 

Yep

 

What filter?

 

The filter is externally serviceable under the air filter housing (on 04-06). They are usually pretty disgusting with clutch shavings like what you get on the plug.

You need to change the Z1 as often as every oil change - the base does not last. ...or at least switch to a product with a better base, if not a better base with less friction modifiers.

 

Doesn't one ever get tired of posting the same garbage!

Let's close this one!

 

Nope.

As soon as the members get tired of helping people and tell them to search all of the time, then boards start to die. Since I plan on owning my TL for another 250K miles, I will happily keep people around by helping them, even if I teach them how to search, so that this board will be around when I need help later. We all will have issues with these cars as they approach 200K+ that we don't even know about yet - I don't want the knowledgeable to disappear like they did on the Honda Accord boards that I used to go to where they only way that you can get anybody to answer your thread is to title it an engine swap.

 

props to you, sir.

 

I recommend you do this as well: http://www.acura-cl.com/forums/showthread.php?t=729149

 

Helping others is what this site is all about.

 

How can this be helping people, change the ATF every oil change? It's ridiculous and you definitely have no automobile background as it makes no sense at all as the OP already mentioned the ATF has never been changed and the car has just passed 150,000 miles.
I was going to continue, but a waste of time to some......
Sarcasm, yup.

 

Actually it says that the trans was serviced once. What kind of service and at what mileage we don't know but it was probably at least 1 drain and fill if not a 3x3. It was also starting to shudder prior to the current servicing. I think a drain and fill of Z1 every change is overkill too but some would rather be safe than sorry.

 

Yup, I stand corrected.
Once again, I have no problem if someone wants to change their ATF every 5,000 miles, but don't profess it to be a must due situation because the base does not last and the posting is helping people.

 

I am sure that this guy would love to hear any opinions and suggestions that you have that might help him. Don't direct them at me, rather help him out if you have something to say... I have my mind made up about the Z1 and I don't need to have this discussion. Otherwise, this board just died a little bit if all that you want to do is critique members and their opinions while offering no actual help of your own.

He thought that he might change the fliud with every oil change. At $12 per, he is speaking about a 1x3, most likely. In post #11 you said that it was ridiculous. In post #13, you said that you have no problem with it. You might consider helping him out and reconcile these statements. Consider that a 1x3 with every oil change (at 5K, I am supposing) is likely a 3x3 every 15K on a tranny with known wear issues. I am sure that this guy would love help from everybody.

 

I think it is important to simply reiterate the fact that changing the fluid is important, that's why I posted the thread. The fluid was changed (Drain and fill) once at 105K. Spending $12 (for me) every few months is much better than a couple thousand dollars.

 

This thread was really helpful for me. I don't understand why some people just can't keep their mouth shut about others helpful advice

 

Why wouldn’t I direct the rebuttals to you as you’re the one that posted that the ATF should be changed every oil change because of the deteriorating base and the OP was only posting about the positive story concerning the ATF change and not asking any questions, so why volunteer?

What’s not to understand:
Also, post #11, yes, it’s a ridiculous statement and shouldn’t be construed as mandatory maintenance.
Post #13 states that if you want to throw your money away every oil change that’s fine, but it is far from a recommended schedule.

Once again the OP was not asking for any advise, so I certainly agree with the statement why some people can't keep their mouth shut.

 

Ya I do need to do that, I'm trying to kind of stretch out some costs and thats going to cost me about $70 for both from my dealer so really not that much.

I just read about 45 seconds ago the "talk with my transmission builder" thread and it makes me really want to replace them, the tranny does seem to hesitate shifting, probably wearing it out faster

 

DITTO^^^^^^^^^^^^^^

I drained 3 Qts out @ 103,000 replaced with 3qts of Z1. I have no problems This was the FIRST and ONLY service done to my tranny

I have 111,000 and doing fine.

I purchased the car new and my driving is "mild aggressive" with 70% of the miles on the interstate.

 

Everyone is entitled to their opinion. Everyone can tell of their experience.

We do not permit personal attacks. Some of you are walking on thin ice.

Let's keep it civil so that mod intervention is not required.

 

How can one challenge an opinion if they are not permitted to be confronted or challenged?

Do we just allow anyone to voice and opinion and that's the bottom line?

Guess I need to give in once again and agree that this thread is extremely usefull as everyone should change their ATF every oil change!
EOC

 

Of course you can challenge ideas. You may agree to disagree. Opinions are like elbows. Everyone usually has a couple. Express your opinion and respect the fact the other members may have a different opinion. You can support your view with your experiences and conclusions and they can do likewise. Other members can make up their own minds. And you can debate things all day long without making it personal or name-calling. It's really pretty simple.

 

OP congrats on the flush. Glad it solved some issues. But I too disagree with the notion of changing the tranny fluid every time the oil is changed. I'm sure you can figure that out though since you work for a Honda dealer.

Mine's been changed at a rate of about every 35,000 miles. Even that would be considered unnecessary by some. I used the factory-recommended Z1.

 

I have done a drain and fill X3 twice on my 2004 with 22k miles.

I know it's not necessary and I haven't had any problems. I'm just an overly cautious guy who goes overboard on maintenance.

I just did an oil/filter change even though the Maintenance Minder said there was still 90% Oil Life. I only had 1,000 miles on the old oil but it had been a year since the last change.

 

Round and round we go...

First we need to clarify how long an oil change is and whether or not we're doing a 1x3 or a 3x3 at each interval. To some people 10,000 miles is one oil change interval and to others 3,000 miles is one interval.

9 quarts every 3,000 miles is a lot different than 3 quarts every 10,000 miles.

Z1 oxidizes very quickly, that's been proven time and time again through UOAs. Z1 has to much FM causing extra wear.

It's not that crazy to do a 1x3 with each engine oil change. That would be the equivalent of a 3x3 every 30,000 depending on your oil change interval.

If the trans was shuddering with the old Z1 you can bet it will come back eventually with the fresh Z1. The only way to keep if from coming back is to use a type f fluid and replace the pressure switches.

I'm done here, there is enough transmission info on this site to write a book.
