I took my truck in to get the engine and tranny flushed... seems they did a reverse flush where they send about 14 quarts of fluid through the system backwards... it caused a couple of leaks but a gasket change seemed to fix it.. I noticed moisture/drips several times after but nothing crazy like the frist time I had to bring it in for the new gasket... I'm coming up on my 90K soon but don't want a repeat.. did you guys by any chance have service doen prior to the leaks?
