This Oil Cooler is a MUST when doing a 3800 Engine conversion, as the stock oil lines and oil cooler are not large enough to meet the requirements of the larger 3800 transmission.
Constructed in radiator style with 3/8" oil line in and out for maximum fluid flow.
This unit is far superior to the factory radiator cooling system, which by design is already at 200 degrees, thus providing minimum cooling affect of the transmission oil. Transmission oil should not exceed 250 degrees. Our cooler keeps the oil temperature under 200 degrees.
The cooler the oil, the longer the life of the transmission.
