Tranny seems to "chug" when shifting into 5th gear while the A/C is running
For the past couple of months, whenever I turn the A/C on, and drive normally, I feel the transmission shift into 5th gear (at about 45-50) followed immediately by a "chugging" or series of pauses. The tranny fluid is clean and full, and this does NOT occur when the A/C is off. Any Ideas?
