Alrighty, as you may or may not know oils come present with specially formulated additives for whatever application. In this case an auto transmission. Automotive manufactures know this and know that there transmissions require this grade of oil with these certain additives to fulfill there service intervals, whether they be 30K or 100K. If your transmission service is due every 30K in "normal driving conditions" then "flushing" your tranny at say half of that 15K, can actually cause more wear on the components, mainly clutches.
WHY???? How can changing my fluid much sooner possibly affect my trans even more???
ADDITIVES
Oil additives are activated by heat and pressure. Due to additives having to hold up over time take certain time periods to actually become active at protecting your transmission. They take time to bond to the wear metals.
Back to work, i'll answer your questions tonight Ben and add some more to this also.
Continued 6:01 PM : So to help make this clear. The first couple thousand miles on new oil is where about 90% (give or take) of wear occurs. As the miles rack up additives become more and more present doing what they are formulated to due, protect your transmission. This also goes for motors and diffs with some different exceptions of course. So now you can see why changing your oil too soon can lead to "accelerated wear." It's the repeated early service of the trans that puts the the oil in the "activation period" or "break in period" over and over again increasing wear. Failing to follow the guidelines of the manufacture.
Keep in mind about all this, these are pretty much today's current oils not late 80's or early 90's oils. Oils have come along way and new advancements have been made hence these absurd 100k service intervals and 10K motor oil services. At the end of the day though each shift is one less shift for the tranny regardless, it's still man made don't try to go 200K on the poor things.
I won't be surprised if any of you didn't follow what I'm saying in previous posts like knowing oils had a "break in period" so if I get reply's about that's bull shit this and that, it's okay. You don't have to follow what I'm saying, choose to believe what you want. I'm here because I enjoy checking out your bitchin cars.
