Overheating 3208 in a 90SP36

[Jeff Miller]

The turbo engine could use a tranny cooler in more extreme
conditions, but I felt that the cooler installation in Ernie's
old 'bird, an air/oil cooler on the bottom surface of the RF
compartment with a rock-guard was an excellent addition on the outlet
of the radiator-cooler. With the 250hp, 4.63:1 gears, towing, and a
lead-foot I never saw alarming temperatures in that rig running 15psi
boost on any mountain I could find. The airflow under that
compartment is excellent, and high-pressure (high-density), enough
that you'll notice the foam insulation is eroded away on those
compartments in many coaches. The air there is pressurized by the air
trying to get around the front of the moving coach, and having to
squeeze between the ground and bumper. The differential in speed
between the coach and the road makes the air quite turbulent, also
good for cooling.

Try synthetic fluids also, most people on RV forums agree that it
runs cooler in automatic transmissions.
