Ford 3-speed transmission main drive gear retainer. I pressed the oil seal in then realised I'd fitted it the wrong way round. I did check but somehow on the way to the press I didn't re-check and pressed it in. The rubber lip pointing away from the oil. Do the seals work both ways or will it leak? Has anyone done this, like I did - duh - and found it leaked? Annoying because I'll need to order another one if I pull it out. Thanks Ed
