We've been hovering around 100F for weeks, so it's been a good time to check out the A/C install and the B&M remote trans cooler. My experience with this '34 has been far from glitch-free, but I'm very happy with these (fairly) recent adds.
The radiator has no trans cooler tank, so I hung a B&M thermostatically controlled heat exchanger behind the rear axle. In all of this Texas weather, the engine temp is rock steady at 180, and the trans temp at 150.
The Vintage Air MK-IV unit is amazing. I have to keep it fairly low to avoid frozen cajones.
