Not much data but it's something.
The interesting part was some people didn't even drop the pan (changed filter), just flushed the fluid, if the new trans fluid will "clean" and "dislodge" crud etc, we'll see failure even more on these seven people cases. No?
I am not arguing with anyone, but as a member of this board I think we all need to point what works and what not. I am not advising people to flush, and if that's the "stupid" thing to do so be known on this board so others don't follow. I don't get paid by Esso or filter OEM company  |
Good question. If owners are going to change the fluid, then IMO it is imperative that they change the filter at the same time. It also isn't a bad idea to go back in a few days later and change the filter again, because it will be after the new fluid is in and has a chance to clean out the internals that one is more likely to get complications.
It really isn't a flush (which uses a special machine, similar to kidney dialysis), but rather a fluid change. Flush is a bit of a misnomer, again IMO.
I don't think that anyone is stupid because they decide to change their fluid. If I had shift problems, it is something I would be likely to do. On the other hand, if I didn't have any shifting problems, I would be unlikely to touch it. I don't think changing the fluid in an otherwise good transmission will be likely to cause a failure, but I definitely think it increases the odds of such a failure, based on my own experience.
My real issue is simply that some people change their fluid for motherhood reasons, because they don't believe the fluid can last as long as the transmission, and those are usually the people who are most surprised if they have a problem afterwards. I think people should make informed choices, that's it. No stupidity is involved in any informed and balanced decision, IMO. I respect individuals' decisions, I just think they in turn should respect other's decisions which may not be the same as their own.
