Just had the radiator soldered to fix a leak. The radiator wrench lost some tranny fluid taking off the cooler line. He added some fluid and the dipstick said it was low so he added more and now it's too full. I checked it after driving, so it was good and hot. It's about an inch over the top mark. Is this too full? Should I drain some out? What's the best way to drain it? Topsider? Thanks.
