Just brought a '90 and noticed a leak that I didn't notice when I inspected it. 1st Nissan ever to own. Looks like it is coming from the side of the trans the dip stick is on. Leaks when running. Wondering if this could be a seal and wondering what is might run to have fixed.

Paranoid in Florida.

 

I'll need a little more detail in order to help you with this, but could it be that there's simply fluid leaking from the filler pipe (dipstick tube) or drain plug?
