Blackstone said: "The TAN still reads at 0.4, so we are thinking this is a normal level for this type fluid after running the oil a normal use interval in a Honda transmission. Aluminum (torque converter, usually) still reads mildly high at 27 ppm, but the rest of the metals are at or below average, and are showing no signs of a problem. Since you've changed this fill of oil out, we have no further suggestions to make based on these data. Suggest going 15,000 miles use for the next sample. We will watch that aluminum level for you."

The 1st analysis they said the unit average for iron was 111, this time the unit average is 71 ppm. As a result, I didn't put the unit averages. It doesn't seem like they have had enough ATF analysis experience to know exactly what to make of this especially the TAN. Terry will be consulted on this one before my warranty goes out.

Fluid was drained at this sample and refilled with 3 quarts of Honda ATF-Z1.

I mailed the package on Monday from Alabama & received my results via email Wednesday. Very impressive.

Thanks for any comments.

Just remember thats a 5 speed automatic!!!!!!!!

Aluminum seems pretty high, but the copper is pretty low..so your tranny may use more aluminum than other brands. I have no idea why that zinc is so high

Bear in mind that you probably only got less than half the ATF out when you drained so your results represent a mixture. You need to do about 3 drain and fill cycles to get 90% of old stuff out.

Interesting. Zn may be an additive....but without P it's very interesting. Note the B.

Nope. The 5 speed auto wasn't put into the Accord until the 7th generation (2003-present).

Yeah, the total capacity is 7.2 qts if I remember the service manual correctly. My plan is to drain & refill with 3 qts every 15k miles.

Looks like a good plan benjamming. I plan on the 15,000 mile drain on my 97 also. You are keeping everything looking good at 15,000 mile changes!

Their zinc is high because their transmisssions are essentially manual transmissions with hydraulic clutches, and zinc (as ZDDP or equivalent) is needed to reduce wear.
