2003 saturn vue 3.0L, transmission fluid leaking badly. Changed front seal,still leaking. What is the cause of the leak,What could be the fix for this problem

Front tranny seal

The cylinder that activates the throw out bearing is inside the housing for the transmission. You have to pull it anyway.

The leaking component must be found and replaced or repaired. I dont know how a "garage" could have bled the line with a leak in the system. Take it back, get your money refunded or make them find the leak and fix it.

Do you have a leak? Is there red oily fluid under the car? If not then you just have a defective transmission. As to checking the level that requires a special tool. there is not dipstick.

It is most likely the front seal on the Tranny, or a leaking tranny pan gasket.
The rear seal on the engine would leak motor oil

If you have no leaks dont worry about it. Just get it serviced if its time. Alot of cars are this way now. You need to be under the car to drain and fill. My BMW is this way

mine did the same thing. Where the steering column goes through the firewall (floor) there is a rubber seal. That seal has gotten dry. Apply a small amount of lube where the shaft goes through and turn the steering wheel. This helped eliminate my squeal.

Yup, you are sure it is the frt seal ?

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.

the front shaft seal is bad on the transmission,pull out the transmission and replace the front seal which is about$8.00 for the seal
