Give this a read. Linkie

I have the same Hayden #679 installed on my Dolphin MH with A43D automatic transmission. I generate losts of heat with weight, headwinds and a torque converter that does not lock up. I have a gauge with sensor on out line too cooler (where fluid is at highest temp) and I am very pleased how well the Hayden works in keeping transmission in FSM specified temp range.
