I pulled the engine and tranny out of my car, did a little work on the engine, and then put them back in. Now I'm losing tranny fluid at an obnoxious rate: about 1 qt every 500 miles. I'm assuming it's leaking becuase I don't know where else it could be going. But why? Is there something I did wrong when I put the torque converter back on? That's the only thing I messed with (besides cooler lines) and it wasn't leaking before. Is it possible to get a leak from removing and reinstalling the TC?

Where do you SEE oil on the tranny?

 

The car sits too low to really see under it and I don't have a jack now. But the spot it's leaving on the ground is on the right side of the car, seems like it's coming from the back of the engine on that side. So I'm figuring it's the front pump seal. I didn't replace it when I reinstalled the TC. Why would it leak now when it didn't before?
I suppose it could be the tranny cooler lines leaking somehow, but I kinda doubt it.

You will need to look at it to be sure. Baby powder on it may help you to see it too. In that area are the cooler lines, Servo and filler pipe.

 

My guess is front seal.

Although, l did have one of my cooler lines get about 1/12 of a turn loose and that was all it took. Went to work and when l came back it was almost empty.
