I think lower gears could only help, but I've never had my AT over-heat enough for the light to come on. I would recommend 5.71 gearing for a 3.0/auto with 33s or bigger actual tire size. I say actual because some manufacturers sizes don't really measure up to what they print on the sidewall.

I've bought 3 radiators for 3 different vehicles from 800-radiator and only one (for a BMW 328i) have I had any problems with. I'm getting ready to test out their lifetime warranty on that BMW radiator because it's leaking enough now to pull it out again and replace it. It is one of those plastic radiators though, I hate those things. The one in my 93 truck is all metal and no problems with that one since putting in one from 800-radiator about 2 years ago.

Weezy,

Where is your x-tra tranny cooler installed? If it's behind the radiator (or otherwise blocked from receiving cold air front the front), moving it to another location will improve its performance significantly.

BTW, I had a Hayden tranny cooler installed in mine a few weeks ago. So far, no A/T Oil light. Of course, daytime high temps have dropped off significantly from my Sept. drive when it was 99 degrees in the shade. The real test comes next summer.

The tranny cooler is in the front of the radiator, visible through the grill. There was a difference though when I took it out. The trip I went on it used to overheat about 5 times total, but this time it was only once. Just a little closer to getting "cooled off." Glad to hear you are staying cool!
