i'll take the word of someone that has nothing to gain over someone that has everything to lose every time.

in the interest of full disclosure, go back and re-read my reply above. I added to it after you quoted and responded.

not that it will matter much in the end as I can already tell your opinion won't be changed, but if there is something more there to talk about then it could be worthwhile.



The manufacturer has nothing to gain by telling the truth if that means recommending increased PM? I disagree. The manufacturer's reputation increases if their product is more reliable and lasts longer. They gain market share and increased sales volume which grows their company and leads to more profits.

You say that the consumers are swayed by Consumer Reports and maintenance costs into purchasing vehicles with lower costs. You claim the manufacturers claim lower PM to increase their sales. Then you claim that the buyers choose to ignore the recommended PM intervals and go with an increased PM schedule. That makes no sense. You can't simultaneously claim the consumers purchase cars due to lower PM costs and then claim they ignore those PM schedules when I point out the cars are not falling apart as you claim they would be.

It's in the best interests of the shops to recommend an increased PM schedule. It makes them more money.

This is turning into too much of a debate club exercise and not an educational experience. You can go on thinking there is some big conspiracy against your vehicle and you have some "secret" information on how to make it last longer and I'll go on trusting in Toyoda-san.

Safe motoring.

This is nothing new.


and how do you know its NOT coming from their engineers???

what I said was that they have nothing to gain by admitting they didn't follow the recommendations made by their own engineers.

do you think that they have something to gain by such an admission?
I'd bet they do it.

I bet those airbags that are causing all the trouble weren't the engineer's first choice of airbags, but rather chosen based on other criteria (cost)

with respect, that is only your opinion.
others buy on other criteria.
to that point, I wouldn't buy a Toyota truck unless Ford made it for them. We all have that "thing" that we are looking for

do you really believe that?
no consumer has ever been sold a service by an auto shop, whether well-meaning or not?

c'mon. people say one thing and do another all the time.

if one is choosing between two vehicles they like more or less equally, they have to choose somehow and maintenance costs can be a deciding factor for many.

but you don't think they might get sold a service or change their mind, or forget that a transmission flush would have been included in the maintenance cost they looked at 6 years ago? do you really believe that people, as a general rule, are so iron-clad in their convictions about vehicle maintenance?

never said otherwise. only pointed out that because of that, many people are getting their vehicles serviced by shops that don't follow the different manufactures' differing recommendations.

sorry you feel that way.

its not conspiracy theory when you have proof:)
and I've offered more proof than you have
smile.gif


you offered your example where you neglected your truck for 280,000 miles and it still worked fine as proof that manufacturers recommendations are good enough. fair enough.

i'll offer the transmission we had go out at 70,000 as proof that they aren't.

you could claim it had an inherent problem, and I can claim that a fluid change at 60k would have saved it.

do you really think that Toyota-san would tell you that they filtered their engineer's suggestions through the marketing department?

I've got an engineer who said it has happened to him. where's yours saying that it doesn't happen?

until I heard Mark say it, I never even really considered it.

in other threads he also said that the marketing department (NVH engineers) soften up shifts and ignored cooling recommendations (cooling department) which hurt durability in both cases, and cost many people a new transmission.

do you really think that the product you drive is the exact product the engineer designed? Engineers get ignored quite often. not everyone has the same appreciation for conservatism that engineers do.... ask me how I know.

I agree ..........

Any wonder today we are still seeing components failures ..... (which previous versions prior to it does not fail )... despite cumulative experience/knowledge gained during the past century or two ... and trillions of dollars of R&D on automotive engineering..

If first hand words from a former transmission engineer isn't good enough, how about from someone with his boots on the ground?

I'll offer this for your consideration:

https://www.youtube.com/watch?v=9ME93NO9fGE

fast forward to 5:10 and he specifically addresses why the factory recommendation is not the best advice to follow.

here's another:

https://www.youtube.com/watch?v=Nse_z9RmPcQ


am I the only one who can see the corporate filter? Apparently not, because Brian specifically says "for marking purposes, ect"

if it is all in my head, I'm not the only one.

When I bought my current 07 F150, new with 6 miles on it, I asked (2) Ford trans techs their advice on keeping my transmission serviced. It has the 4R75E transmission. They both recommended that at 24K miles, drop the pan, install a new filter, and add a drain plug to the pan. I tig welded a 1/4" thread o let to the pan, changed the filter, and added the 4 qts. of Mercon V fluid. From then on, they suggested to drain the pan every 30K miles and then add the 4 qts. of Mercon V fluid. Every 60K miles drop the pan and change the filter.
I have been doing this since 24K miles and the fluid looks beautiful. I use only (3) makes of Mercon V fluid in it;
1)WMST
2)Castrol
3)Motorcraft
All 3 have the Ford approved spec'd stamped number on the bottles.

You were the one that just a couple posts above was asking for facts, now it's all about "believing" because the facts presented did not align with your perspective

Because if you were involved in any type of design and manufacturing field you would know that after the engineers are done with their designs, their work is handed over to the purchasing and technical publication departments. The purchasing guys will try their best to get what the engineers want, but they're always pushed for the lowest price. So a compromise is agreed upon. The same process applies to technical publications and maintenance schedules.
Engineers are of course involved in most of this, that is why you do not see catastrophic failures for the most part.

I'm involved with this type of work on a daily basis and it is in the aerospace industry, which is extremely regulated when compared to automotive industry so our engineers have a lot more "voice" in these decisions, but the compromises still have to be made. It's just part of doing business and staying competitive.

That is correct, HAD the 4R70W. Now it has the 4R75E.
 
We had an Audi A4 with a 6speed automatic. Audi's manual and dealer states it is a life time fluid, never change under any circumstances.

The manufacturer of the fluid "ZF" - states replacement at 60,000miles for severe and 100,000miles for normal driving.

Strange indeed.

How'd that happen?

it didn't. he has the 4R70E, not the 75E.

from the 2007 ford technical data

would be no reason to have a 75E behind such a small engine, the 70E is already blessed overkill

What's your VIN?

I won't give out my VIN online but my door jamb decal reads "Q" under the transmission code. "Q" represents the 4R75E. Do I have to go take a picture of my door jamb decal to prove to you I have a 4R75E transmission in my truck?

What facts were presented? The facts I've been asking for as follows:

Maintain a tranny as per Toyota which says the ATF is lifetime and compare it to the same tranny with the fluid changed every x miles and see if there is a difference in failure rates, repairs, etc.

The only thing I saw presented was "Mark said so". That's not facts, that's opinion and conjecture. I don't know who Mark is. And I trust in Toyota a lot more than I'd trust in Ford. But that is another topic.

In the absence of facts, we have to base our decisions on when/if to change out the ATF on something.

I'm guessing you're the type that also covers the license plate when taking pictures, right?
