I got burned on using some Denso Iridium Power plugs for my van. After 35,000 miles, 3 out 6 plugs were down to the nub---the iridium tip was completely gone. The gap was maybe double what it was supposed to be. Van started running poorly was how I found out.
I preferred Denso and NGK before...

I did purchase the Denso spark plugs on Amazon a few years ago. The seller was Denso.
I seems like it might be too risky to buy Denso or NGK spark...

Yep, or some major engine defect or malfunction. Denso along with NGK make well-made spark plugs. The iridium ones in my old Sienna, ECHO and BMW look very good even after 100,000...

I ordered some Autolite Double Platinum on Amazon recently. They looked fine. The seller was identified as Fram.
Nobody is counterfeiting Autolite

Don't worry if the transmission fluid is black. For some reason these new synthetics light viscosity fluids all turn black, when in fact they are fine.

I am aware that this PCM is capable of handing multiple fuel...
Reports are that people have completely solved their shift problems with this transmission by running Premium gasoline. That simple.
The poor shifting appears to be a computer/software issue, and the higher octane seems to solve the problem.
Sounds like LUBEGARD would be perfect for you:

1 or 2 bottles of Lubegard Red in this problematic transmission.
Question regarding NAPA and CARQUEST.
Both of these seem to cater to mechanics, and are a step above Autozone and OReillys.
Do NAPA and CARQUEST have almost the same suppliers, and sell almost the exact same parts (but under their own brand name)?
I've actually had very good results with Bosch Sparkplug Wires that I bought at autozone.
They were reasonably priced, and there have been no problems with them--they don't have the bad reputation that Bosch Spark Plugs have.
I don't doubt that Amsoil is a quality ATF--probably better than Dexron VI.
That said, I don't know if Amsoil is SUBSTANTIALLY better than Dexron VI, so to warrant its high cost.
If I am not mistaken, isn't Mobil 1 ATF just as good as Amsoil (similar add pack, similar base oils) and for a few...
