What's a "typical" operating temperature for an automatic transmission? If anyone, especially other Scan Gauge users, could post their temps and vehicle specs, I'd like to see them. I have a 5-speed auto (Ford 5R44E) filled with BG full synthetic fluid. I've got a factory trans cooler too. I've had a Scan Gauge since December and have been watching trans temps since then. The operating temp after several miles of driving ranges between about 145*F in colder temps (20*F-35*F) and 170*F in warmer temps (70*F-80*F). I haven't had a chance to monitor the temps in hot weather yet. Most of my driving is around town with a lot of shifting. At what fluid temperature should I consider a larger cooler or deep pan?
