Hi - Did anyone have installed transmission external cooler yet? I am considering to install transmission external cooler on my diesel cruze . I got scangauge II that comes with diesel cruze firmware last week. When I was driving on freeway and the transmission temp came to 220 degree. I do not believe that it should be normal temp at 210-220. It should be at least 175-195. My Cruze now at 30K and I will take it to service to have the fluid and filter replaced very soon. I had 1995 Chevy Suburban, 4L60E tranny busted at only 85K. Removed the tranny and opened, the wirings are all melt because it ran over 300 degrees even parts already burnt. It does not have tranny gauge. Later I bought 07 Chevy Avalanche with 4L60E. I quickly installed tranny external cooler - Hayden Rapid-Cool 679 and it runs at around 140 degree. The lower temp, it lasts longer. Now at 110K without any issue. I require to change tranny fluid everyt 30K no matter what. So I thought I would do the same thing for Cruze. I want to drive Cruze to 300K miles without any issues on tranny. So I am looking into Hadyen Rapid-Cool 676 or 677.
