I've got a problem with the seal on the passenger-side of the transmission leaking oil. I just got through replacing the driveshaft and it's dripping pretty badly... leaving little puddles of oil wherever I go and having to fill the transmission over and over isn't fun.

Is this a driveshaft problem or a transmission problem? And if it's transmission, where do I go to get a new oil seal?

 

if you are sure its tranny fluid then replace the oil seals. If you have thicker grease dripping it could be a leaking cv boot.
