Trans cooler questions

Most of these transmission cooler discussions are very qualitative rather than quantitative. It would be interesting to see some real data from people with trans temp gauges and before and after readings to see how they really perform. These discussions are usually completely void of any real data.

All I really know is that I have had very few transmission problems, so I assume my transmission coolers are doing thier job.
I don't know how much experience you've had with rubber trans cooling lines, but I've run into 3 different occasions in the past 10yrs: 2 intrepids and a stratus where rubber hoses have leaked. 2 of the three were due to barbed fittings, overtightened gear drive hose clamps shredding the hoses. The third was a factory rubber hose in the middle of two steel lines which became saturated with oil and just sweated ATF. So, yeah rubber hose may work for you, but I don't think the convenience of rubber hose is worth the risks.
