Default tranny leak problem on t350

i have a 81 scottsdale and i just put a new 350 in it and i also changed the torque converter about month ago.its a t350..but for the past week...its been dripping on the flywheel cover,the trans. lines are alittle wet,frames alittle wet and the trans. pan is wet on the bottom and also the bolts...i took the flywheel cover bolts out and there was only 2 cause thats wi put in when i put it on and they had transmisson fluid on them...i'm thinkin its the torque converter or the seal on the tranny.....any other advice?

hmmmm might be pan and blowing around . . I know mine leaks from a corner of the pan cuz it's bent a little. . .but when you replaced the converter did you replace the front pump seal? . . . but that should only leak while running

T350 TRANS HAVE HAD ISSUES WITH THE BEARING IN THE PUMP. THE BEARING IS DIRECTLY BEHING THE SEAL AND THE TORQUE CONVERTER RIDES ON IT. IF IT GOT PUSHED FORWARD UP AGAINT THE SEAL IT WILL CAUSE FLUID TO PUSH PAST THE SEAL EVEN THOUGH THE SEAL ISN'T BAD. THERE IS A GAP BETWEEN THE SEAL AND BEARING WITH A HOLE ON THE BOTTOM FOR THE FLUID TO RUN BACK IN THE TRANS. THE LEAK WILL BE WORSE DEPENDING ON HOW CLOSE THE BEARING IS TO THE SEAL. IF ITS ALL THE WAY FORWARD IT WILL PUMP ALL THE FLUID OUT.
