I am talking about Honda's book stating that transmission fluid is good for 120k miles (going from memory), and (seemingly) every 6 cylinder car they have made since 1998 or so having transmission problems. This is a case where following the "book" can get you in trouble.

Both my Accord and CRV say 30k for severe conditions which is what most people should probably follow. I think any lack of maint. is more the owners fault rather than the car maker.

If you want to compare car makers check my daughters 02 Grand AM where the automatic transmission doesn't even have a dip stick and the owners manuel says it's not necessary to change it. I think that's asking for trouble.

But yes sadly Honda did have some huge problems with their automatics.

So I guess Honda's stuff is a no silicate, low phosphate formula?


For some years the typical Japanese coolant (green or red) contained no silicates, but had a heavy dose of phosphates and other inhibitors, including a modest amount of one or two organic
acids.

As you may know, DexCool uses two organic acids: sebacate and 2-EHA (2-ethylhexanoic acid).

Recently Honda and Toyota both changed to an extended-life OAT coolant-made with sebacate but no 2-EHA. Sebacate isn't quite as effective in combating corrosion at lower pH levels, but the Japanese aren't concerned with cast iron engine blocks so they don't consider this a problem.

The Honda and Toyota OAT formulae are no-silicate but add a dose of phosphates to provide fast-acting aluminum protection, especially against cavitation erosion/corrosion.

Honda specifically recommends against 2-EHA and high silicates in replacement coolant, and that looks like good advice for Toyota as well.

Zerex G-05 looks like a good prospect for top-off and replacement of the Toyota and Honda coolants, and that's the recommendation of NARSA to its members. It's a HOAT (hybrid organic acid technology) low-silicate no-phosphate formula. The
organic acid inhibitor it uses is benzoate, used for years in American, Japanese and European conventional coolants.


This is excellent information but still confusing for those of us who don't know squat about chemistry.

Does anyone know where the Prestone Extended Life 5/150 fits in? I think someone in another post said it's DEXCOOL like but not actually DEXCOOL. It's orange colored and it's what I have in my 00 Accord since last spring. No problems and looks fine so far.

Prestone Extended Life 5/150, the orange dexcool approved/labled one, or the "mix with all yellow bottle" are the same. They differ from Havoline Dexcool in that Havoline uses Potassium 2-EHA, whereas Prestone uses Sodium 2-EHA. I am not aware of any other "dexcool" formulations that uses a 2-EHA other than a sodium or potassium based one.
 
Chris is right. Prestone "yellow jug", SuperTech, and Prestone's DEX-COOL additonally carry a second organic acid salt - sodium neodecanoate. Whether that offers any performance advantage over a single carboxylate (another big word for these organic acids) as used in Havoline/Mr. Goodwrench DEX-COOLs is anyone's guess. DEX-COOL is DEX-COOL is a GM trademark, regardless who makes and markets it. The trademarked name references a GM coolant performance specification, NOT a specific forumula or product. (I dare say, if someone tested tom cat pee and found it met GM's coolant performance specs, it could be licensed and sold as DEX-COOL - hmmm... depending on the state of "Mr. Kitty"'s kidneys, it might not even need the orange dye...

) All manufacturers of products that use the name DEX-COOL have payed GM a license and tested and swore on a stack of bibles or submitted their brew to GM for testing for approval. They ALL state "GM Fully Approved" (or wording to that effect) somewhere on the jug in addition to the DEX-COOL logo. What you're getting with reformulated Prestone "yellow jug" and SuperTech is the tradesman entance to DEX-COOL land - same forumula as the Prestone DEX-COOL, but dyed green and without paying an extra buck or so for the almighty GM licensing fee.

Agree, but for how long? Driving by the Toyota dealership the other day I noticed around 6 in a row of sixth generation Accords (2001-2002) like ours on the lot. Probably the ones with the transmission problems. When it comes to sell it, is the buyer going to remember that the recall stopped at 2001?

is a buyer even going to KNOW there WAS a recall?

why do you assume the cars on the used lot are someone's problem child? Most likely they are just lease returns, that's the largest source of 1-2 yr old used cars today. Many still have the factory warranty. Any financial advisor will tell you they are the best value out there.

Admittedly, I don't know much about leases, but wouldn't a leased car get returned to a Honda dealership? This was a Toyota dealership's used cars. You are right, there could be extenuating circumstances, but I was struck that there were that many of that year model range.

Just going from personal experience, I research cars before I buy them. I guess I expect that others do the same. However, I don't usually talk to financial advisors when buying a used car.

BTW, it wasn't a recall but a warranty extension. It won't show up on as many people's radar this way.
 
Tones,

Is it possible that the Accords you saw at the Toyota dealer were from 1998 or 1999 or 2000 since those sixth gerneration Accords share the same body style as the 2001 and 2002 Accords? Four to six year old cars on a used car lot aren't be that unusual.

In these earlier years (98, 99, etc.) Honda was recommending 45,000 mile/3 yr. ATF changes. I don't know what they were recommending in 2001 and 2002.

Cheers.
 
Not convinced that Honda's transmission problems had anything to do with fluid change intervals. Sounds more like a design/materials problem.

I'd say the same thing is true with GM's Dexcool disaster. Faulty design / material selection and air pockets caused corrosion and deposits. That doesn't mean that the 5yr/150,000 recommendation, or a 10 year 120,000 mile recommendaton (in a properly designed and full system) are wrong. Just keep an eye on it and you'll be fine.

You're right, it had nothing to do with the fluid. The clutch pack materials were faulty, causing bits of it to fall off and plugging everything up. So the transmission litteraly starved itself of fluid.

People had transmissions fail before 30k, which is the standard ATF fluid change reccomendation now.
