Have the car up on jackstands right now and I've found that the place where the tranny leaks most is from the speedometer cable. Now I wonder if there's anything special I should think about before I start. The transmission is still in the car btw.
I suppose there is some kind of gearwheels behind the cover, anything special I should think about when I take the parts apart and put them together again?
I've searched the archives but found nothing detailed about changing these gaskets.
There is an O-ring on the sleeve and a seal on the inside that rides on the gear. Both parts can be found at most parts stores. You will want to check the gear for wear as well. Any grooves in it will cause it to leak.
