This continued dwelling on the vent isn't addressing the root problem. Either vent style will work fine with a properly configured and properly filled transmission.
Again, the FULL mark on the dipstick is about 1/4" above the ledge where the dipstick tube inserts into the case.
Trust me John, I am not ignoring your solution. Your reputation is simply unchallenged in these things. I really don't think the vent has anything to do with it either. After all, there were plenty of '66 and earlier transmissions that functioned well. I do know that one thing is that I have the wrong pump support for my application especially since I am using the later input shaft. I think the best thing to do is to address both of these issues as the possibility is that you two could both be right. We have two separate issues and they aren't necessarily mutually exclusive of each other.
