Transmission Running Hot

[Fubar]

Hi all; if it's not one problem it's another At least it seams that way for me lately.

Here's my current concern; while climbing long grades or steep mountain passes my trans gets hot to the point where "Transmission Hot" appears on the center console.

I know simply pulling over and leaving it in park and letting the motor run for 10-15 minutes brings everything back to normal. It's just a pain..

But considering I'm not towing anything and the trans is reaching this "Too Hot" condition, I'm wondering if getting a larger trans pan, one that will hold an additional 3 quarts if this would solve this problem?

I guess a larger trans cooler might also help but with my recent past engine running hot issue, which I can happily say has been solved, anyway with this past trouble in mind I don't really want to stack something else in front of the new radiator.

So would something like this work? It say it supports up to yr 02 and the list of trans that it says it will fit doesn't list the one in the Hummer (Hydra-Matic 4L65-E).
