Need advise; My 93' Ranger XLT extra cab 2wd, 4.0 engine and A4LD auto tranny with 126,600 miles has a rough downshift into 2nd gear about 15 or 16 mph. Down shift to 1st is real smooth and upshifting thru the gears is smooth. I just put a new modulator valve on it and it helped the upshifts smooth out, they were getting to be hard shifts before changing that valve. I do not know if there is any adjustment that can be made to smooth out the rough downshift when slowing down to a stop for red light. The U-joins are in good shape and new carrier bearing assembly on driveshaft and no extra play in the rear end. A band adjustment maybe or just have to live with it.
