To all esp. the A/T specialists,

Or to those with any contact to "Mr. Bulaong and Co." in this thread.

I'm planning to connect an external cooler in series after the factory internal cooler inside the bottom tank of the engine rad since i experienced slippage after i installed an 82C thermostat. As per my research on the net, optimum operating temp range for A/T is from 60 to 80C. Therefore, with engine operating temp of 82-93C, i'm overheating the ATF thus the slippage.

The question is: which hose should go at the top of the external cooler? Hot fluid from A/T or should it be the Return hose for the A/T?

i'm confused since some threads say hot fluid in at the top then cooled fluid out at the bottom to prevent aeration...some say otherwise since hot fluid is lighter than a relatively cold fluid.

Transmission is Aisin AW0372 mated to 4d56turbo....

TIA
