What are you paying for ATF+4? Any good deals out there at national chain stores? The Napa website says $6 a quart local price for the NAPA brand, $7 a quart for Valvoline. Is the Walmart Super Tech ATF+4 trustworthy?
The specifications for atf+4 requieres both properties and ingredients so they
are all practically the same. So use wallmart without hesitation.
Note that fex dex3 specifies only properties so here is quality much more diverse.
