Where the speedo cable enters the transmission the plastic gear and the piece that hold it in place get worn. They have to fit snug together and still turn freely! They do both wear over time and no longer seal the fluid in! If they are both worn, replace both pieces and it should be ok.
You can check if it leaks there with a inspection mirror when it is happening. You can raise the front end and secure it with Jack stands safely before looking under!
