Question Over-filled trans?

I accidentally over-filled my tranny during flush and noticed fluid leaking from the rear of the tranny somewhere near the top.

Likely leaking out the vent tube or did I just lose a seal?

If you overfill the trans, the fluid will foam up, expand and puke out all over the place. After this happens, you will often find the new fluid level is low. It is probably just leaking out of a vent tube.

I use a small hand pump, looks like the pump that you sue for hand saop but for pumping oil, to fill rear end oil and manual trans. I have used the same type on pump to suck oil out of the rear ends and trans. You can use a long hose down the dip stick tube to suck out some of the oil.

1/4 inch polyvinyl tubing, the white, stiffer type used to hook up refrigerator ice makers, works really well. Most tubing small enought fit down the dipstick tube is not stiff enough to push through all the way down to the pan level. I use this and a hand vacuum pump (Mity-Vac) to remove fluid. Home Depot/Lowes sells this type tubing in the plumbing section.

The drain tube for the transmission is the one you see on the driver's side, near the front, coming down vertically. This steel tube snakes a long way, near the top of the transmission before making its way back to the top mounted vent spout. There, it connects with a piece of rubber tubing. If the rubber connection tubing is still patent, you should be seeing purged fluid coming out the of the drain tube.
