My 2001 tundra transmission calls for dex merc 3… I used to buy Valvoline dex merc 3 from Walmart all the time and would do a lot of drain and fills. Well the blue valvoline bottle I used to buy that plainly stated “dex merc 3 “ is no longer available to buy.. now it just says “dex merc”. Is this stuff the same as the dex merc 3 stuff? Just a label change? And no, I don’t mean if it’s interchangeable, I want to know if it’s the same exact fluid but just a labeling change. I want the same fluid I have in there in it, more importantly I want the same fluid the engineers said to put into it. I don’t want a thinner synthetic Dexron 4 fluid in it, I want good ole stupid, thick, shear prone, old school dex merc 3 in it as my transmission will last 450k+. THANKS!!!!
