i had a bad front bushing. it spun and basically trashed the whole tranny very quickly. sent lots of metal everywhere. if i ever have one start leaking fluid from the front it is coming out immediately. my tranny guy said that the bushing holds the fluid in more than the seal so if you have a leak in front its most likely the bushing. the bushing had seized onto the converter. trashed the front pump, planetaries, rear over-running clutch, valvebody, and a drum, oh and of course the converter. better get it looked at
