I just serviced my Suburbans transmission about a week ago. Since then, my tranny slips. I changed the filter and used Dexron 4 fluid. My parts guy said that his computor showed that it took 5 quarts,so thats what I put in. When I checked it, it was way over full. I drew some out to get the level in the crosshatches but it still slips. My dipstick says to use Dexron3, but my parts man said Dexron 4 was all purpose and should be fine. It almost seems as if the torque converter is going out. It has cut the engine off at stoplights twice. HELP!!!
