I take it this a manual gear box and the seal you refer to is the pinion output shaft seal? It sounds like your gear box has a severe fault, maybe a chewed up bearing and this is causing the output shaft to precess which will open up a small gap with with the seal allowing fluid to exit. When the seals were changed what did the transmission oil look like?. Was it opaque and murky - it should be clear and red. Drain the gear box and collect the fluid through a muslin cloth and then insert a finger in the drain plug hole and feel around the base of the gear box. If there is a thick layer of fine grey paste on the gear box bottom plate this is bad sign it is casing material. Does the muslin cloth contain any particulates of hard metal, theses are fragments of case hardened gear teeth. If so the gear box is done for and will need replacing. It might be possible to repair the box but the chances very much are that getting a good used one from a reputable breaker will be much cheaper. Always do the finger check on a gear box when drained of fluid - the stuff that sticks to your finger will tells you a lot about the general condition. A good gear box free of wear has no deposits.
