What are you using for a cooler? If your returning oil above the temp it
should be running at it may not be helping much. There is a reason many oil
coolers (trans or engine) use oil to water heat exchangers. They are
remarkably effective. The vanagon automatic gets a lot of its cooling from
the torque converter itself. Remember this transmission set up was used in
the air cooled with no external cooler at all.

Subject: Auto tranny cooling

Just installed an Autometer tranny temp gauge myself. Sensor "tee'd" into
transmission cooler outlet line back to the transmission. Runs about 185-210
degrees F, but got north of 250 degrees F ( pegs gauge) droning interstate @
105F OAT (outside air temperature) on current trip out of Phoenix to Big
Bear Lake, CA. Transmission fluid just changed when I installed the sensor.
When checking tranny fluid after droning on I-10 it was correct level and
red. I do  need to check outlet temp from cooler with infrared gun when I
get home from current trip.

I have a '89 Westy automatic with 2.2L Subie conversion.
