Transmission Flush

   / Transmission Flush #61  
That's easy...same way it's been recommended and done for years. Despite the things that have been implied or suggested thus far, there's no reason to try and out-think the manufacturers. If they say to do it differently, then by all means I will.

I've asked the question several times here and elsewhere, and it never gets a straight answer:

Are manufacturers aware or unaware of the amount of fluid that gets changed when a pan is dropped? I'm going with aware. Change it at recommended intervals, using recommended procedures and recommended fluid. There's no reason whatsoever to go looking on the 'net for "transmission flushing secrets". If they want a fluid "flushed" they'll say so. I find it borderline hilarious that while some folks claim "flush" and "change" mean the same thing, they also believe that there are several types of flushes to choose from, and that some are preferable compared to the others. Where's the logic there?

At work, we came across a similar situation recently, when I noticed another tech removing an oil cooler on one of the Deutz diesels we have so he could empty the oil out of it. I inquired as to what he was doing, and he said he *needed* to remove it during the oil change "to get the dirty oil out of it".

It says right in the manuals for the equipment and the engine itself that oil will remain in the cooler, and that draining the pan at recommended intervals and using the proper grade oil is all that's required. In other words, the folks that built the engine KNOW the cooler doesn't empty when you take out the oil pan drain plug.

So while his efforts were commendable, they provided no real benefit.

I'm not *against* bucket-flushing or whatever else an owner wants to do himself or herself, but look at the multitude of conclusions a perspective DIY-er could draw from this thread:

"Flushing and changing are the same thing"

"This type of flushing is better than that type of flushing"

"I'd do the bucket flush, but not the reverse-flush"

"I read a post from a guy that worked in a lab"

"I do it this way and maybe that's why I haven't blown a tranny in 20 years"

Put all those, (and more), statements/claims/opinions in a single thread, shake them up.....and what have you got? More confusion than an unfamiliar DIY-er came into the thread with.

So can we all pat ourselves on the back and say "mission accomplished", or....would something else be more appropriate?

Broke, don't have my manual with me now (2004 silverado) but do have one for the truck I'm driving at work, a 2001 dodge ram. It says the " the fluid and filter should be changed and the bands adjusted at specified in the maintenance", bla bla etc. I could not find where it says to change only the fluid in the pan. Maybe it's assumed? Or maybe it's assumed when it says to change the fluid they mean all of it.

You guys are fighting a loosing battle here. We each have our own opinions. I am with the change as much as you can camp. After going though 2 trannys in my Dodge in 68,000 miles it was what I was told to do by the dealer, Jasper transmissions, and many trusted mechanics. Its what I do. You do as you wish.:laughing:

I have no dog in this fight as I do both "change" and "flush" depending upon the circumstances. But in reviewing the 9267 page FACTORY service manual for Dodge trucks which includes the 5 speed transmissions, the attached is the ONLY reference to servicing the transmission. Of course in order to further confuse the situation, MOPAR refers to this procedure as Fluid and Filter Replacement.

Note lines (2) a & b under the Transmission Fill paragraph. To me it suggests a standard fluid replacement is pan only.

Make you own judgement on what they are suggesting.

2x on doing as one wishes. Some vehicles have shipped with lifetime fluid 'per' the manual. :D

Gale, I did the fluid exchange that you posted on this site, which I'm sure many many people appreciate here. It was as you stated a very easy ( and clean) job.

liledgy I a glad it worked out well for you. It really makes me feel more clean knowing our transmissions are filled with clean ATF and the fluid was the only cost. :thumbsup:

When I first read about it I was saying there is no way it could be that simple based on what some charge for a total fluid change out so I was surprised at how easy it was. Then I wanted to kick myself for not having done it years ago. :D

I would like to point out that most transmission problems are not going to happen under the warranty so it's not really in the manufacturers interests to clearly spell out to the home mechanic the correct way of doing what they call of at the service intervals.

This is the point I've been trying to get across. They also don't say to "not do" a lot of things. So....do we do what they recommend, or do we do what they don't specifically either omit recommending or "don't not" recommend?

I certainly couldn't disagree with that.;) It's true that what I find from Ford says to change the fluid. It doesn't say to flush or not flush. But it also doesn't say how to change the fluid. Now I don't have a service manual; only the owner's manual and what I read on Ford's website. So you say these factory trained mechanics at the Ford dealership haven't learned how to do it right yet? I'm not sure how long this dealer has been around. The first time I was in the place was 53 years ago, and the old gentleman who owned it died last year, but both son and daughter are still in the business.

Now I'm all in favor of you and others doing whatever you want to do to your own vehicles, but personally I'll go with the factory trained folks.:laughing:

Enjoy that warm weather. You driving the new truck or flying?

Either way have a safe trip.

We're back...We flew down. 80 and sunny every day in Disney. It's like 20 here in PA now. What a rude awakening that was going to get the car...Oh well, it was a pretty nice trip.
