[W126 Coupe] Oil leak - transmission advice

[Iain Gunn]

I suggest that your change the transmission fluid and filter first and see 
what happens. Many times that will solve the slippage and shifting issues. 
The rear seal at the transmission is common. While I drove mine dally it 
hardly leaked, but when the car sat, it would leak more.
