Review on 🔧 Valvoline DEX/MERC ATF: 1 QT Case of 6 – High-performance Automatic Transmission Fluid by Johnny Black

This is the blood of the TH350 transmission and works well in our custom rigs. Even a small amount of water will destroy the paper seals in the gearbox and require repair, so I change the fluid frequently. You can't beat having Prime delivered to your door. You can save nearly half your dollar by checking out the two-week up-and-down cycle here.
