John, at Toyauto in Mesa, tried to save me some money, but I really didn't like the transmission temps I was observing last weekend on our trip to the rim. The last mile or two of each long climb were warmer than I wanted to see. Water temp was managed well, but the transmission temp would climb uncomfortably high. Based on some input from people that use their truck much harder than I use this one, I ordered a B&M cooler and got it installed today. Don't have any data with the trailer, but from what I'm seeing driving around town, we should be seeing the 25 degree drop that others have experienced. The transmission will thank me!
John had me in and out in 90 minutes and included me in decisions about where to mount the cooler, how to route the lines, etc. I'll be back! Update: The cooler was installed Friday morning. A handwritten note thanking me for my business arrived in the mail on Saturday! Wow!
We're really looking forward to the trip north this summer. The list of stuff to fix is getting shorter and the list of stuff to pack is getting longer. Less than three weeks to go!
