Is that blue sealant stuff better than the white high temp stuff? When I changed my trans oil a few months back, I used the permatex high temp thread sealer. Now I have a slight leak, more like a drip coming from the drain plug. Should I switch to the blue stuff? I read that you are suppose to wait 24 hours before you fill with oil again. I didn't do that and filled up right away. Man I hate leaky cars.
