·After installing Oil pressure/temperature and Automatic Transmission Fluid Temperature guages, I was shocked to notice that the Automatic Transmission Fluid temperature after a 50F day with 20 minutes of normal driving, measured just before the OEM cooler (I figured was worst case), was 220 F! Running at this temperature, the ATF could be expected to last approximately 25,000 miles before total fluid replacement was required. Well, that just won't do. Solution? A Stacked Plate 16kgvw viscous bypass oil cooler mounted vertically behind the main grill. The ATF now operates within the range of 165-175 F with the same conditions. At this temperature, the ATF can be expected to last for approximately 100,000 miles. Maybe it's just me, but after installing the cooler and driving it hard for awhile, the shift points were as crisp as when I started. Previously, without the cooler, they didn't seem as crisp as the ATF heated up.
