Good luck with that auto tranny. I had a blazer with the vortec 4.3 and an auto tranny. I had that damn transmission rebuilt more times than I can remember. I am sure it had something to do with the place that was rebuidling it. Unfortunately I was stuck going back to them because it was always still under their warranty and I was in college. In any case, change the tranny fluid often. I would recommend every 30,000 miles, especially if you are towing with it.
