Usually if the front seal leaks,you probably need to inspect the torque converter hub. A front seal is really just a dust seal. If there is too much clearance between the pump bushing and the converter hub, a front seal will not stop a leak.I don't want you to put it all together and have it leak.then you will just have to pull it back out.

Hey, just chimeing in. Its hard to tell from a picture but mic it and look at it if you see a wore spot on the shaft you could get a new torque convertor. Or you can get a repair sleeve kit form auto zone or advance that will take care of that. Just a thought good luck

It is hard to tell from the pic.where the bushing rides on the hub looks but it looks like you have some wear at the very top of the hub.it doe's not look polished like the rest of the hub. The upper part is where it engages with the pump gears. I personally would pull the pump, check the gears and install a new bushing before installing it.

A leak is a leak! Whether it leaks when is running or sitting is hard to say. A lot of times,centrifugal force from the converter causes the fluid to fling against the inside of the bellhousing.when the engine is off, the fluid gradually runs to the bottom of the dust cover and falls to the ground. A slow leak will not hurt anything as long as you keep it full.but it is really aggravating!

X2^^, on checking the Pump, something's causing wear where the Pump Gear rides, possibly bad Bushing. May also want to check the TC snout for runout.

I'm guessing it the torque converter making the leak, i got it pressure tested at a trans shop they said it was good. I did change the seal and the bushing and bought the front pump non leak kit the gasket and big o ring around the pump and washers for the bolts, so that's y I'm thinking it the converter that's the only thing i did not change even though they said it was good. russ moore transmissions.

i want going to put it back together yet but i was doing a frame off and didnt have the money to get the converter at the time.

I really don't know but I have had several factory converters that looked just like yours on the snout. I have never had a pan gasket seal 100 % and the last drain kit I put in a pan had a very slow leak. I'm not an expert by any means of the word, just relating my experiences.
