This is why it’s critical to change your motor oil and transmission oil frequently in breaking in both. Removing contaminants until you see a stabilization in Parts per million. Looks like the engine is stabilized, but the transmission needs a few more flushes. The transmission fluid on my Type R transmission after two changes is still off the charts — consistent with lake speed juniors analysis on his Toyota, which means I need to flush out all contaminants from the transmission to maximize longevity as all break in metals float in the fluid and caused the most damage with the engine and transmission. It also explains why my transmission feels much better every time I change the fluid and there’s a question as to is people‘s perception to changing to a different brand the difference or the fact that they’re flushing out the transmission fluid no matter, you have to clean those wear metals out. Data data data is the only truth we can empirically measure. This is exactly why in my first startup we analyzed all flight data recorder data, and built systems for the major airlines, and we adjusted maintenance schedules based on data. This transmission fluid data proves you need to flush it out much more than I expected. I should’ve been changing it with every engine oil change (2-3k miles) until I saw ppm stabilize. It’ll be interesting to see other people’s Gear oil analysis, and parts per million and see if it performs better than the OEM fluid.
