I have a muncie from a '65 Chevelle. It is not in my car yet because I noticed it is leaking. Its ;eaking below the front shaft whcih there is a black circle. I'm wondering if this is some type of relief thing that can leak if the trans is not level or If I have a problem to deal with before I install the trans

I think on a Muncie, the countershaft is driven through a hole in the case just under the input shaft. It is a press type fit and the ones I have seen have sealant placed over the area once it is driven in. That must be what the black circle is. I don't know what can be done about it except maybe scraping of the old sealant and re-sealing it.

Thats the countershaft pin as Rich253 stated. If you have a leak from the pin hole it's because the hole is oversized. Depending on how bad it leaks you have a few options. You can use some silicon sealer, have the case rebushed, find a better case or use a new countershaft pin that has an O- ring on the front end to seal the trans hole. The O-ring pin can be bought from Larry at D&L at 631-351-4837.

Hope this helps

I've had several Muncie transmissions leak at the case where the countershaft is pressed in. The usual cause is the previous rebuilder "peened" the case to try and achieve a tigher fit around the countershaft. The local rebuilder here in Detroit machines the damaged aluminum from the case on a Bridgeport mill and installs a bushing. Real slick.
Contact Liberty Gears in Taylor, MI for more info. Can't locate the phone number off hand, but it's 313 area code.

It would be easier and faster to change the case. That is a 325 casting if it is original to the car. The counter pin is 7/8. There is a ton of those cases around. Send me an email and I will put you on to someone with a good case.
