Why does my transmission stutter or hesitate when I backup? Does not do it in forward? If I really give it gas it will stop? 160,000 miles. Transmission serviced 4 times in life of car. Have had a complete flush of the tranny recently.

Mercury Mountaineer Transmission Stutters In Reverse

I guess this to be a 2000 Mercury Mountaineer with the 302 V8, 2 wheel drive, with the the 4R70W transmission. If so I would suspect wear in the reverse band, low pump pressure in Reverse only, or a problem in the reverse servo.
