Long time user of max life in all of my autos including a built 47RH, and our durangos 845RE. Looking to do a pan drop and filter change on my newly acquired 84 chevy c10 with a TH350, along with subsequent drain and fills to get all old fluid out. I love maxlife and it has been great(originally recommended by my Trans builder for the 47). Question is I'm seeing the Castrol transmax HM for roughly 10$ a gallon cheaper lately. I know it meets spec for the th350, but how does it compare to the maxlife overall?
