Water cooled trans?

Harry, I had a 1966 Caprice 396 and it had a remote choke (I'm unsure whether or not it used water temp to actuate but I believe that it did). The choke coil was in a small well in the manifold that was beside the

Some of the smaller and low powered mid sized cars of that era from GM had air cooled trans instead of running the fluid up into a heat exchanger built into the radiator.

Most likely the water cooled reference was a sales hype intended to show just how well built the little Buick was. Since heat is the biggest enemy of an automatic the reference to mountain driving would have fit right in.

If you ever see a pic of a torque converter with fins on the outside and the torque converter housing has 2 or more large holes in it then you have seen the air cooling method.

- New Super Turbine 300 water cooled transmission for 21 % more thrust. ( Even has a built in barometer to improve performance on mountain roads ). -

Is this just a reference to the trans cooler in the radiator? Did the cars before 64, not have a built in trans cooler? I assumed the radiators always had a built in trans cooler.

A friend had a 64 LeSabre with a 300 V8 and it had a water operated choke on the side of the 4 bl carb.
