willwren,

I am considering my options regarding transmission coolers. I like the internal viscosity-regulated bypass function of the Tru Cool coolers. I notice you use this brand.

I do have a question, though; do you believe there is a significant difference in the ATF level in the pan when the fluid is in "bypass mode" versus "full core flow mode"?

If so, how do you rectify it?

I haven't been able to get any info or specs on actual internal volume/capacity on these things...

The pan level never changes. The cooler is always FULL, regardless of where it'* flowing at any given time. The 'cold' side when bypassed is a reservior in a sense.

Thanks for the info, willwren.

Tru Cool it will be.
