i went to Jiffy lube to have my transmission flushed. I had the transmission pan dropped and filter changed in january of this year and i noticed the fluid smelled like varnish. I know it because it didn't get all of it out. So anyway, they flush it and put MERCON IN IT!!!!! NOT MERCON V LIKE IT CALLS FOR! I tell the guy this and he added a Mercon V additive package. Car runs OK so i thought maybe it worked. WRONG! The car wouldn't shift under load at WOT. Had the car at the 3 different shops. No engine codes or anything. Everyone was stumped. Sure as **** i brought it to Ford and had it flushed with MERCON V. PROBLEM GONE. So i had my fluid flushed twice in 100 miles. At least my transmission is free of gunk and is squeaky clean ...and i will be calling corprate!!!!!!!
