Interesting (to me) notes include the titanium blip on the radar (in some engines ok but in an AT!?), low TBN, ever decreasing amounts of zinc (mentioned previously), & the viscometrics (also mentioned previously).

I plan on beginning 7500 mile OCIs now, or at least for the 3-4 next OCIs when my RLI case will empty.

Why are you putting so few miles on your tranny fluid?

 

[benjamming]

One reason is that a drain & refill only replaces 3/7 fluid capacity. Another reason is that this trans really stresses ATFs. As I said, I do now intend on increasing the drain & refills to more than double the current practice. Should I have simply done a flush & went straight to 7500 mile OCIs, maybe. I was also interested to see the interaction of ATFs as they progressed.

Ummm.....OK

DOn't switch so often. I suspect you still have good amount of Amsoil in there in the mix.

Keep the same fluid for at least three analyses to get a decent trend.

 

[benjamming]

I should explain. Every so often I will get a Dyson analysis to complement the Blackstone analyses. I don't like grouping the Blackstone results with the Dyson results due to different test methods & instruments used by the different labs. If the person reading understands up front the respective differences then fine, but usually it is a cursory glance. That is why I have included the '% tested fluid' on each. This latest sample is actually ~ 88% RLI Biosyn so the samples should be comparitive in that respect.

You know, I was talking to Bill a few days ago. I should have asked him about the viscosity of his ATF vs. the spec sheet but I wasn't thinking about ATF at the time. It's cool you're posting up your ATF analyses, benjamming. Thanks!
