I have 91 525ia M50 engine with A4S 310R automatic transmission. I found a leak from the selector rod area. See the link below:

I suspect the shaft seal is bad (number #2 in the figure). Does anyone know how to replace it? Do I need to drain the fluid and remove the pan? Any easy way to fix it?

Thanks,
Jerry
