Oil Leak
« on: July 14, 2006, 03:02:14 PM »
Our Muncie 4 speed (original to the 1967 Camaro) leaks oil around the input shaft. There is no seal behind the front cover. We understand that this was fixed in either 68 or 69.

Does anyone know of a fix for the leak in the early transmitions?

Thanks in advance

Muncies never had a seal at the front bearing - lube that made its way through the bearing was deflected by the nut, ran down the inside of the flange on the bearing retainer, and drained back into the case through the drainback hole. Make sure the bearing retainer gasket is installed correctly and isn't blocking the drainback channel. Many report that running the lube level about 1/2" below the fill hole (instead of even with the bottom of the hole) minimizes this issue.
