WS, WS, Redline D6 ATF UOA

[Patrick0525]

It took 10 yrs to collect this data on the 2014 Venza V6. Toyota dealer flushes so it is WS, WS and D6.
I am not sure if the dealer used my D6 atf since the viscosity dropped from 6.2 to 5.5 but the funny thing is that the P is 493 ppm from two different labs.

If God is willing in another 5yrs in 2029, I will post a HPL green uoa.

Good maintenance history.

Was that first line, the 9/2016 at 39,xxx miles the first time the oil had been changed?

Yes, I bought it new and that was the 1st atf change. Sorry it is a typo.

I appreciate you posting this. I was curious what that first drain looked like on a Toyota transmission. Interesting to compare that first drain with the subsequent to see how wear metals change over time. It looks like the metal contribution in ppm per 1k miles dropped off a lot after that second change, despite having almost 50k miles on the fluid.

U are correct. Up to 88k it was all Toyota WS. It is important to flush it out before 40k to get all the debris out.
