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.
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.
in dip stick tube
In the dip stick tube .
down the dipstick tube
Transmission fluid is usually added through the dipstick tube.
look for a filler tube coming from the transmission on the passenger side
Down the dipstick tube.
For automatic transmission: remove transmission dipstick, put fluid in dipstick tube with funnel. be careful not to overfill.
