Flo-Dynamics offers the TSD450 Dual-Access ATF Exchanger, which enables two methods of ATF exchange in-line through the cooler or through the ATF dipstick. The dipstick technique allows easy service on vehicles with difficult cooler line access or vehicles without cooler line adapters. The unit implements a 2.5 GPM pump to provide speedier service and comes with a standard adapter set, a dipstick access adapter and tubes.
