I have a small leak in my transmission and was told by the dealership that it is most likely the torque converter front seal. Is this a common/plausible problem? Should I wait until it's more of a problem? To fix it would require removing the whole transmission and the 2003 was designed so well that you cannot add more transmission fluid yourself.

Re: Transmission Leak. Torque Converter Front Seal?
I know that GM dosen't have a fill/check tube on several models. They use a plug on the side of the unit (like on stickshift transmissions) I'm sure there would be a similar item on your transmission otherwise after a rebuild, there would be no way to refill it. If it's a small leak you could try using a good sealer/conditioner such as Lucas, which may help you a lot.

Hello , You could have a leak at the transmission dip stick tube o-ring, the front pump gasket, the torque converter seal , the transmission output shaft seal or the transmission oil cooler lines. I suggest you put the car on a lift to make it easier to see where the leak is coming from.
Oil leaking around a starter is usually one of three possible things.
If it is motor oil, then suspect the rear main seal.
It it is auto trans fluid, it could be from the transmission front seal or the torque converter
If you have a manual transmission, it could be clutch fluid leaking from the slave cylinder, or a leaky front seal from the transmission.
did you use lock tight on the torque converter bolts when installing them? it may be coming loose and ruining the seals. It doesn't take much. You may have some kind of buildup on your output shaft or a bur of some type that is cutting the seal. Check the outside hub of the torque conv. for roughness or spurs. The seals should work if everything is done right.
My 93' Stang has the same problem. Well you got a few things there, most likely the front pump seal. That seal connects your torque converter to the trans and allows fluid to flow through it if that gets worn it may leak, but it will usally do this if the engine is running or when it gets put under a heavier load (ie: Driving up a hill) it may still leak if the engine has just been shut off. could also be torque converter or flexplate im still working on that soloution.
TRANSMISSION LEAKS COME FROM TRANSMISSION OIL PAN GASKET LEAKING.OIL COOLERS LINES LEAKING.LEAKING AT TORQUE CONVERTER FRONT SEAL.TRANSMISSION SPEED SENSOR SEAL LEAKING.FRONT AXLE SEALS LEAKING AND LEAKING AT TRANSMISSION COOLING LINES TO RADIATOR.CHECK ALL YOU WILL FIND LEAK.IF YOU HAVE FAST LEAK OR PRESSURE LEAK.WITH CAR RUNNING IN PARK EMERGENCY BRAKE APPLIED LOOK UNDER CAR IF YOU SEE FLUID LEAKING OUT IN LARGE QUANITIES.COOLER LINES LEAKING OR TORQUE CONVERTER FRONT SEAL LEAKING.IF YOU HAVE SLOW LEAK THE LEAKS HAS TO BE AXLES SEALS OR PAN GASKET LEAKING OR VSS SENSOR SEAL LEAKING.
If it is the shaft seal on the torque converter, you don't have to open up the case, You will probably have to replace the torque converter, once the seal digs in like that and starts to leak, it cuts a path deep enough to where it can't be fixed. Hope this helps.
Dont waste your time and money trying to use a transmission stop leak product, they don't work on large leaks, you say the leak is excessive in this case the you must remove the transmission to access and remove the torque converter, after you have removed the torque converter carefully inspect the torque convert imput shaft for wear and also you will need to visually inspect the transmission front pump bushing for wear also, I have seen it all to often people just replace the seal thinking it was just a seal failure, well more times than not there is a reason for seal more than just the age of the seal, excessive wear on trans pump bushing and torque converter imput shaft is usaully the cause, check and repair those as good practice during this repair unless you just like to do the repair over again for free... also check the torque converter run out, sometime when they are repaired they are welded back together somewhat crooked which will cause it to spin off of a true center, this will cause immediate damage to transmission. Check also your engines crankshaft end play for looseness this can cause wobble which will transfer to transmission causing this problem as well... do the repair thouroughly and who ever does it for you have them check all that I listed and you should get a good repair which will last without issues.... please rate my help thanks...
Your question is not complete but I assume u have a front seal leak on the transmission? this is the torque converter seal and it requires the removal of the trans to fix it/replace it, if the torque converter has a grove worn in the area where the seal rides you will also have to replace the torque converter. There are trans leak seal sweller chemicals out there, they will slow down or stop the leak for awhile, but in most cases this is a short term fix, also throughly clean the trans first (car wash works great) before any work and make double sure the leak is not from the trans pan gasket.
