I took out my drive shaft. I noticed that the output shaft from the tranny is pretty loose. It seems to have alot of slop. There is also oil leaking out from the back of the tranny. Is this becase i removed the drive shaft?. Is the out put shaft supposed to have some slop in it? Is it ok for oil to come out there with the driveshaft out? What action should be taken if this is not ok?
