Review: Great quality and price - I bought 10 gallons to do a transmission service on my Allison MH4000 transmission. I couldn’t see spending the money on the Allison fully synthetic fluid to only end up mixing it with the Dexron 3 in my transmission. It’s been 5000 miles and transmission performed flawless.
