Have 1999 ford taurus front wheel drive car that transmission leaks.does not always leak but when it does it leaks a lot while driving.fill with oil and will do fine for several weeks without leaking and then will have to put 4 or 5 quarts of fluid in to fill. could it be getting hot and building pressure causing it to blow oil out.

if it is a auto the fluid is transmission fluid leaking from the oil cooler at the radiator or loose hose so transmission is low on oil thats why it wont drive .have a closer look at where the oil is leaking that will help but filling it up with oil is only a very short term fix .You need a mechanic to check it out if its not a loose plug or cracked hose.

check what colour the oil is firstly--- red --transmission oil==black --engine oil===dark brown --gear/diff oil. Next check the position of the oil between the front wheels - red -transmission cooler lines leak /power steering leak
black between the front wheels-- front crank seal. If you have a front drive car then you will have to be careful but the colour will tell you what is leaking and where.

The only gear oil near the throw-out bearing would be in the transmission and the only way to the throw-out bearing is out the transmission front bearing retainer. I would check the vent first. It's on the transmission top. If that's free you'll have to remove the transmission and front bearing retainer to check the front bearing and seal.

valve cover, intake manifold, front crank seal,timing cover, a quart per 1000 miles isnt a small leak.

if it is the front seal, you did not indicate whether manual or automatic, but the seal is generally 15-20 bucks, its the labour time that costs the most, my suggestion is if its manual, possibly think of doing the clutch at the same time, or if its automatic, having a tourque converter service as well

2 things
cooler pluged;
converter is overheating

Check all the oil cooler hoses They come out of trans and go to bottom or side of radiator You need to clean all the oil off everything with degreaser the hose it off Jack car up on axle stands and run it in drive at idle and see where it's running out of. MAKE SURE car is secure on stands and can't fall off !!!!!!!!!! consequences can be fatal

YOU carnt have a transmission oil leak from the front axle on a Falcon as they are Rear wheel drive but could be the hose going to the radiator over the front end leaking But the rear end of G/Box should be only the OIL SEAL.

you will still need add the proper type fluid to proper fill level, get under the truck, clean up transmission so you can visually monitor where the leak is coming from. Chock the wheels, emergency brake set, start and idle vehicle check for leaks. If trans is leaking it will probably be a front seal (oil will drip from small hole in the bottom of bell housing), pan gasket, loose cooling line to radiator, or rear tail shaft leak ( where drive shaft enters the trans.) Don't forget to check the lines for pin holes and the radiator for leaks.

I suppose you mean that there is oil on the floor where it is parked. It's the same as a Ford Taurus, and I suppose you have a 3.3 engine. Lack of oil in the transmission means that it won't go anywhere. If you fill the transmission with fluid, it will leak out again, but you might be able to drive the car - hopefully to transmission shop to fix it. If the car will not drive with fluid added, then it will have to be taken for repairs. What I do when I have a car that won't drive (and has driven to where it's parked) is to add 2 quarts of transmission fluid and then see if it will move. Normally this works & I can move it into my garage for work. Sometimes it takes 3 or so, but thats usually for full size or pickup transmissions. Rick
