ATF Cooler Failures
Stump Everyone
Editor’s Note: This article addresses an unusually
frequent and perplexing product failure for which no one
seems to have answers. For years, and with surprising
frequency, in-tank automatic transmission coolers used
on a variety of heavy duty work trucks, especially snow
plows, dump trucks and refuse haulers, as well as some
school buses and RVs have failed catastrophically as
shown in our cover photo and in the article below. No
definitive cause for these failures have been found,
which has left vehicle and transmission manufacturers
and cooling system distributors and repair specialists
debating the potential causes, and dealing with warranty
returns, associated costs, and the frustrations of not
being able to identify a root cause for the problem.
In response to this article, which outlines a basic
description of the product and circumstances surrounding
these failures, the Cooling Journal is asking readers
to provide any information they may have about
similar ATF cooler failures in order to gather as much
information as possible about when and how they occur.
By compiling the knowledge and expertise of our readers,
especially those from the heavy duty sector, it is possible
we can shed some much needed light on this issue.
