Have a 1996 K1500 Suburban 4X4 with 350 and 225,000 miles, (140,000 on transmission). Past year when it is cold the trans would slip fo a second or two when shifting into drive and then it was fine. This morning when I was pulling onto the highway it started slipping in 3rd / Overdrive and then was ok until about 10 miles later and it seems to have lost 3rd / OD. I still have 1st and 2nd. I changed the tranny fluid about 10,000 miles ago.
