I have transmission flud leaking out of top of transmission on my ford tarus what would cause this to start suddenly I havent added any fluid

the dipstick is located behind the front transmission mount and its held in by a 12mm bolt. you may need to remove the transmission mount to check the fluid. the color of the dipstick is yellow, make sure the car is in park and fully warmed up to operating temerature and on a level surface before checking the fluid.

If you have never done this before,it may be best to take the truck to a shop or have some one with experience help you. You will need the truck up far enough to take out the transmission. The linkage and drive shaft has to be removed,then unbolt the transmission from the bell housing.Special tools may be needed to pull and replace the seal.
Transmission fluid needs to be changed since it is a brownish color.

First off, be very careful here - Transmission fluid is flammable and will start a fire if leaking on exhaust manifold. this can happen if the tranny is running too hot and it's basically boiling over - or if passageways get blocked and the pressure pushes it out. I would start with a fluid/filter change. or you can have it flushed (best if shop does this).. FYI: they will need to change fluid after the flush so you might want to just bring it in to a shop and have them do flush and change fluid/filter all at once..

on the bottom of the transmission pan you will find a nut with a hex or torx in the middle you remove the center plug when the truck is hot and running on a level serface the trans fluod will dribble out if it does not dribble out it is low if it runs out fast a steedy streem it is over full now their is a part that screws into this for a fill if you remove the pan you will see how it works the pan has a pipe/ stack that when full of fluid the top of the pipe is at the full point if you remove the large nut the stack and plug will come out the best way to change the trans fluid is take it to some place that has a fluid exchange equment this will get all the fluid out including the torque converter

it is down on the drivers side of the car about 18 inched from the front it has a tight fit so you will need to have a funnel with a hose, to fix the leak you will most likely have to replace your transmission pan (it cost me $240 at the dealership) the saturn ls1 sits very low to the ground and if you dent the pan it will leak i have replaced mine twice in four years

you need to tighten those fittings with a wrench... if they still leak... remove them and wrap them with a couple turns of "teflon tape" the kind they use for plumbing. the clamps you should use are hose clamps of the same type that you use for radiator hoses... you will note these can be tightened with a socket.... you really don't need to over tighten them but fairly snug... transmission fluid has quite alot of pressure.
