Ok heres the deal. When my transmission is coasting in 3 or 4th it makes a horrible grinding noise momentarily, and then will do the same for a moment once you depress the gas again. The transmission has less then 7000 on a full rebuild, and was working perfectly before I pulled it from my Suburban to put it in my K5 /forums/images/graemlins/cool.gif. I did happen to break a rear ujoint wich caused the back of the 700r4 where it bolts to the Transfer case to break, but I had it welded by a professional, and it looks as good as new. I have unhooked the tcc wiring so this is not the problem, and I have played with the tv some. Please help!
