no it has a vent if it is coming out the vent it is over full.
If you have the 01M Transmission, you can remove the level checking plug from rear of trans oil pan. There is a overflow tube inside the plug hole, remove the overflow tube from inside the plug hole. Let ATF fluid drain. re-install the overflow tube. The filler tube is located above the front of oil pan and has a plastic cap.Pry the plastic cap off with a screwdriver, removing plug from the filler pipe. Refill 3.2 Qts., Full refill(dry) 5.9 Qts.
A lot of newer transmissions do not have dipsticks or fill tubes (I don't know of a transmission with an overflow tube). The transmissions are considered sealed units and are not serviceable...at least not by you or me. Talk to your dealer.
It is important to keep fluids from leaking from a car. Excessive transmission fluid would be coming out of the overflow because there is too much fluid in the transmission, or because the seal has become worn.
To add transmission oil to a 2002 Jetta, first ensure the car is on a level surface and the engine is warm. Locate the transmission dipstick, which is usually near the back of the engine bay, and remove it. Use a funnel to add the appropriate type of transmission fluid through the dipstick tube, checking the level frequently to avoid overfilling. Finally, replace the dipstick and start the engine, allowing it to run for a few minutes before checking the level again.
dipstick tube
NO. You must drain it out to the correct level. To much fluid will damage the transmission before it pushes the fluid out of the vent tube.
