Last summer was extremely hot, normal 15 mile trips to and from work, so I added an additional automatic transmission cooler next to the factory cooler. It helped some, not sure exactly how much. It did not hurt anything. I don't want to kill the second A4LD transmission. I know heat will hurt any transmission. Mileage around 15 mpg.
Then came winter...........zero and below temperatures, normal 15 mile trips to and from work, the engine had a hard time warming up-- gauge was on the very low side of normal, coolant full, new radiator pressure cap, water pump, hoses, new thermostat, mileage dropped to 11 mpg (without using the 4wd).
Would the coolers be also overcooling the engine???
I could put manual valves on the lines to divert the transmission oil between one or both coolers-- winter/ summer or maybe I need to add a louvered door in front of the radiator-- to manually open or close-- winter/ summer???
Any ideas or comments??? thanks.
