See if there is a DERALE transmission pan available for your tranny ...
these include a drain plug and some models, a temp sensor port. They are much deeper, and have air cooling tubes which can really help dissipate heat.
Our application is a heavily re-built Dodge 46RE and it helps a lot on the hot days.
DO get a heavy-duty gasket separately, the pans come with an unsatisfactory cork one from factory. But the build quality and function is excellent.
