Hey, y'all. I was hoping to get some thoughts and advice on my newest problem. I had a really slow leak between my tranny and the bell housing for a long time. I finally got a new clutch last week and along with that a new front transmission seal, thinking that was the source of my leak. Well, a couple of days later the leak started again, same location, only worse. So I pulled the transmission back from the bell housing to check my front seal, but it was nice and dry all around the input shaft. My leak is coming from what my old shop manual exploded view calls a counter shaft. There are two counter shafts on the front of the case, one just to the right of the input shaft and one below and to the left of the input shaft. The lower one is leaking. The upper counter shaft has a silicone-looking plug in it and is dry. The exploded view calls for a plug in the upper shaft but no plug on the lower shaft. Neither shaft appears to spin during operation. As far as I can tell there is no way to seal or plug the leaking counter shaft from the outside other than silicone. I'd love to be able to stop this leak without completely tearing down that transmission. I'm okay with trying some silicone around that shaft but I just wanted to solicit some other opinions before I gave that a shot. Thanks!------------------

IIRC, the countershaft is an interference fit to the bore of the case. You may have a little slop in this bore, which is causing your leak.To fix it, you would either have to tear the tranny down completely and have the bore machined, or... Pull the tranny out, remove the tailshaft. Carefully tap the countershaft back into the case a 1/4" or so. Smear your favorite sealant on the inside of the c-shaft bore, drive c-shaft back into case, reinstall t-shaft with a fresh gasket...

Thanks for the tip, Hemikiller. Since I've already got the tranny pulled back I think I'll try the silicone fix. If that doesn't help I'll take the next step.
Thanks!

Well, the silicone quick-fix didn't work. It was seeping back through before I even got it all put back together. Looks like I'm dropping the whole tranny and taking from there. ------------------

Wade, you might want to make a dummy shaft for the countergear cluster and slide the shaft totally out to look at the end of it. If it's munged up, you may need a new one. Also, what was the condition of the c-shaft bore?

Good idea about the dummy shaft, Killer. I've got a buddy coming over Sunday and we're going to get inside the case then and look at the shaft and the bore. Hopefully they will both look fine and we can just re-insert it and re-seal from the inside out. A new countershaft is fairly affordable ($25 or so) but I'm not sure how much it would cost to have that opening re-bored.
Thanks!------------------
