Hi, there,

I overheated the transmission of my mdx for a minute or two when I was trying to unstuck myself from soft sand going uphill. I put the truck to idle and let it cool down as soon as I saw the "A/T temp" light. I checked the transmission fluid when I got home. It looked all right. The question is: Should I drain and refill the fluid? Thanks.

It certainly wouldn't hurt, I s'pose...maybe one of the more mechanically inclined folks would know for sure...

(snipped from elsewhere)
Anyways, a member mentioned that automatic transmission biggest enemy (in general) is excessive heat. Excessive heat will break down the chemical chain the ATF prematurely and may lead to tranny failure.
Keep in mind I found this on the internet someplace, so YMMV :)

The fluid should be fine for that short a period of time. Change it at the severe schedule this time if you are really worried about it and want piece of mind. By the way, when I saw the pitiful excuse of a transmission cooler that Honda puts on the MDX as part of the towing package, I went out and bought one of the aftermarket coolers for 50 bucks and installed that as preventative maintenance. It has about ten times more capacity that the Honda unit at a fraction of the Honda price. And it is thermostatic so as to not overcool the transmission fluid and to allow it to come up to operating temperature sooner.

Good suggestion. I also think the acura cooler is kind of too small compared to the aftermarket stuff. That is why I didn't buy it. But I don't know which aftermarket model will fit. Will appreciate if you can share info on your aftermarket cooler. Thanks.

P.S. (on) Coolers

Mogur: Did you also upgrade the stock Power Steering cooler? If so, with what?
