Transmissions do not have "Inter Coolers".
The oil to water heat exchanger or oil cooler is on the front of the
transmission.
The torque converter should always be getting filled with oil if the engine
is running.
The only thing that is not quite on top that is sort of external is the
governor. It effects the shift points.

A tranny that doesn't up shift when cold usually has a pressure control
problem or thick contaminated fluid. The governor seal may also be
completely shot but then ATF will be filling the differential section. Also
a common failure.

Subject: AT Intercooler Question

A question has arisen in the rebuild of the auto transmission in my son's 87
Westy.  Hopefully I can ask it correctly.

Does anyone know the mechanism used in the fluid drain assembly of the
intercooler on the top of the AT?

The auto tranny rebuilder is stumped as to how it controls the AT fluid
flow... particularly as it pertains to the torque converter. That is, the
torque converter seems to continuously loose fluid to the cooler. Is this
normally controlled by a check ball assembly until pressure is built up?

Is it a spring and check ball set up?

The tranny shifts fine, after it's once warmed up.
???
Thanks for any help.
