I recently changed my radiator and despite my best attempts, ATF kept dripping out of the tranny cooler lines so I had to top it off. I topped off the fluid and re-checked it after the tranny was hot after a highway drive; the level was properly within the cross-hatches for HOT.
Fast forward to today-- Had to drive several hundred miles for a trip and I noticed the tranny was shifting hard/jerking on the highway. Nothing too severe but definitely noticeable. I pulled over to check the ATF level and the dipstick read about 1/4th of an inch over the max line. I surmise that with the 85°+ temps today and long highway driving, the ATF fully expanded and registered as overfilled in the system. The service area I stopped at had a gas station garage. I asked the lone guy there if he had a fluid pump I could use to pull out the excess fluid via the dipstick tube. Of course, he didn't. I had no choice but to keep driving to my destination. I plan to pick up a small pump tomorrow and pull out some fluid.
I hope I haven't done any long term damage to my tranny. I only noticed the jerky shifting in stop-and-go traffic. And like I said, it wasn't too bad.
