Hey i have a 99 silverado 2wd with the 4.3 and 4l60e transmission. The cooler line had a leak in it and my uncle kept driving it and now it has no 3rd and 4th gears. My question is, is that my buddy has a trans out of a 01 silverado 2wd with the 5.3. Both transmission look identical side by side. Only difference i can see is that mine has a 46 on the side and his has a 50 on the side. I was wondering if his transmission would work in my truck.
thanks
