I just pulled the tranny out of my Euro 500 SE to put in front and rear seals ,it's a good time to check flex plates and tranny mount and change them if the look bad. Over tightening the 6 bolts that hold the tranny pan on is a very common reason for
for leaks.I would make sure it not the pan leaking or the O ring on the end of the dip stick tube before I pulled the tranny it's a big job.If the front seal is leaking the leak will be out the bottom slots in the bell housing.You can do the rear seal with tranny in car..........
