I just put in a rebuilt tranny. I was putting in the tranny fluid and it started leaking. I looked under the truck to find out where it was leaking and it looked like it was from inside the bell housing. Is there a vent I don't know about? Do I have a bad seal? I made sure that I didn't move or remove the tc as I was putting the tranny in. I am at a lose.

Help

 

Was the truck running or off? If running I would suspect the input seal was damaged, could always be the pump seal between I guess?

I want to say you don't put all the fluid in with the truck off, maybe it was overfilling somehow....need the pump turning to get flow to the converter.

 

Thanks ... I think that was it

 

Mine takes 3.5 gallons and it will overflow if I try to put all of it in without starting the engine. I put in about 2.8 gallons and start it and then pour the rest in.
