So.. I'm driving down the hwy on my way home from work with my cruise set like normal. Suddenly I look in my rear view and can't barely see the cars behind me because of all the smoke. I pull over as fast as I can and look under to see tranny fluid covering the under carriage. It's still pouring out from the front of the trans by the flywheel. Any guesses? It's dark now and gotta be to work early so it's gonna have to wait til Saturday before I can drop the transmission and see what happened so I'm just trying to get some ideas

 

sounds like the front pump main seal.

 

Tranny fluid leaks can be caused by a problem with your pan gasket (that's the mechanical seal between the transmission and the transmission oil pan). It gets worn over time. Looks like you need to have it replaced. Hope it gets fixed soon.

 

It's not the pan, it's coming from the bell housing. I'm gonna drop the pan anyway and change the filter but this must be a seal or line. Could it be the torque converter?

 

Nonsense. Those gaskets are made to last the life of the transmission and usually do.

Front pump seal has puked on the OP's tranny as already mentioned. Might be the TC shaft seal, but the front seal failure isn't uncommon.

 

I have seen this in fords before. The filter is clogging up and for some reason pushes the fluid out the front bell housing. I have change filters and fluid and this has corrected the problem on fords. try this before doing anything else.

 

If the filter is that clogged up, the transmission is already toast.

However, since the pump pulls fluid out of the pan through the filter, I can't see any way that a clogged filter will force a fluid expulsion through the front pump seal.

 

It was the front seal from what I can tell, but it doesn't seem to be in horrible shape either. Kinda stumped here, could it have gotten too hot? Somehow fluid was forced out, filter doesn't appear clogged. It's an 07 5.4 4x4 with 109k, just did the cam phasers and all the timing components. Once I fix the transmission up I should be able to get another 20-30k miles out of it... That was a bad/sad joke

 

not sure why fluid comes out the front of trans, (Vent, seal) May be caused by foaming of the fluid, only seen this when the trans was very hot, summer time, changed the filter and problem went away. I think it was on Ford C-6 trany

 

Lucus Trany fix works great on front trany seals.

 

I had this happen on a 2000 Windstar. I know it's a completely different transmission, but it still has a pump, torque convertor, and seals. Going through the Great Smoky Mountains it started leaking bad. We had to stop several times to let the transmission cool. After 45 minutes or so, we would start driving again and the leak mostly stopped until the transmission got hot from pulling up the mountain. Then it would leak badly. Under heat and pressure, the pump seal was starting to fail and actually swell and flip out of place. This caused a massive leak. Letting it cool allowed the seal to go back into position. At 160K miles, it cost more to fix than the van was worth, so I traded it off.

Since when does a non-moving part (the pan gasket) "get worn over time?" (If you used the words "degrades over time" I might have bought it.) This particular gasket is made to last the life of the truck if cared for properly. This only "wear" it sees is when somebody drops, then re-installs the pan.

What did you find out about this, it just happened to me also this week October 2017. I have a Ford F150 2005.... sounds exactly the same to me, I pulled over and waited for a tow. while parked I saw fluid leaking out....any help would be greatly appreciated!

 

[QUOTE=Huey63;5225119]Same thing happened today, 05 150, 09.2019, any answers?
