Good evening
I have a 2005 ford f150. Some back history,
Have had transmission rebuilt with in 19 months. Had truck back for less than a month and transmission fluid started pour out front main seal. Just paid 800 to have it replaced and they didnt fix the problem. I dont know what to do. Any thoughts on what it could be, because the repair shop said they had no idea.
Oh and they said they checked all of the visible gaskets and seals and they all looked fine.

 

If the seal went because it got hard then it could wear grooves in the converter snout which will make the new seal fail.

The shop might have missed it.

I would find a new shop.

 

It's either the front main seal, the torque converter seal, or a scored input shaft that's damaging the seal.

Take it back.

 

I tried taking it back and they said they inspected all visible seals and gaskets and they are all fine.
They refuse to take it back unless I pay them more money!! HELP!!

 

Well, the leak isn't coming from a seal that would be visible unless the transmission was removed.
