I'm not sure HOW that would work, having two sets of cooler lines hooked up to the same transmission? My car does NOT have OEM style lines hooked to the radiator.
When you have both a OEM type trans cooler located in the radiator and an auxiliary trans cooler they are plumbed in series, one flows through the other then returns to the transmission.
With out having aradiator cooler you need to relocate the cooler you do have to a position where it can get some proper air flow.
What the trans fluid look and smell like, if its burnt change it pronto.
