There are no engine codes. I have rebuilt the transmission and replaced the front seal and torque converter and now the leak is worse. does anyone have an idea to what I am doing wrong? I have replaced the front seal twice since the rebuild.
I own a 1993 chevy Z71 silverado. There is transmission fluid leaking out between the tranny pan and the cover to the torque converter. Its leaking pretty good when the tranny gets hot has has been driven. Is this my toeque converter or do I need to buy a new 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.

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.

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...

The front seal could be replaced, and not have a problem. If you have a shop other than a transmission shop do the repairs, make sure the torque converter hub is inspected to make certain its not scratched/scorn. If the trans shifts properly and the fluid is not burned or smells burned, this would be an easy repair. If the trans fluid smells burned, and hasn't been serviced regularly, the rebuild would be the way to go. Also, ask what the warranty for any and all repair are on your vehicle. Normal warranty is 1yr, 12.000 miles in the automotive business.
