Serious 904 oil pan leak help

Hi All, Need all the help i can get!
have 2 young boys makes it difficult to spend countless hours taking this apart and mindless trouble shooting.

Opting for solutions and advice from the A Body Mopar Fam
I am about to change oil pan gasket for the 3rd time.........BUT seeing as that wont be the only solution required.

THE LIST OF PROBLEMS
1.The Oil pan leaks
2. The trans level will no go in park, fires up in Neutral to drive.
3. Reverse pulls really hard with no gas given.
4. Transmission oil appears to be coming from up top of the shift level.

Help.

Selector shaft seal and pan gasket will not fix all those problems. Only problem with my 67 904 was leaking shaft seal. I went ahead and dropped the pan and valve body. Polished the shaft, replace the seal and the filter. Checked the pan for flatness, reinstalled. No leaks. A couple months later the front seal started leaking. Should have known. They are all the same age ( new in 1984). The trans will be pulled and overhauled. Do you know when yours was last overhauled?
