Anyone else out there have this problem?

I live in southern Ontario Canada and my 2006 Ridgeline is a daily driver. At the (Title) stated mileage, I lost power on a major highway. Turns out, the transmission cooler is inside the radiator. The cooler split and the coolant and transmission fluid mixed and went through the motor. THAT mixture also went into the transmission. My TRUSTED Honda dealership was too far away to have it towed there, so I used my trusted local mechanic. After $1275, and a $140 tow, I could drive my truck again.
That being said, my advice is, when your truck reaches close to that mileage, spend the $300 on a new rad and transmission cooler before the damage gets REALLY costly. My truck is still not shifting right and I may have to get one more transmission fluid change, or take it to my dealer. Hopefully, I won't need a new transmission.
Any comments or questions are welcome.

This has been covered here a ba-jillion times. Sorry you experienced a common issue in colder/more prone to rust climates. But $1275 seems really cheap so you lucked out.

Yep, you can read for hours on this topic on ROC.

But I'll tell you this, in case you don't know (& if your indie shop doesn't know)...... you are only pulling out maybe 40% of the fluid each time you drain the transmission.... the rest of the old stuff (contaminated stuff in your case) remains trapped in the tranny to be mixed with the new stuff when you refill. I think you get somewhere around 3 1/2 qts out when you drain, and the entire capacity is maybe 8 1/2 qts or so???

It will require at least 3 drain & fills to get most of the bad stuff out (I'd recommend 4 or 5 after a bad contamination). If they did a bladder type flush of some kind, then this wouldn't be required; but shops that can do that are few & far between. DO NOT let anyone do a "power flush" (pressurized) on your RL tranny. Bad juju. :(

Here's hoping you just need a few form D&Fs to get you running well again. :)

And for the OP, this is not just a RL issue, but applies to other Honda/Acura vehicles as well as other manufacturers too.
