This may be a dumb question. I was breaking my cam in last night, and after the car had ran for 1 minutes at 2000-2500 rpm my transmission started puking fluid, about a quart and a half came out. It looks like the front seal blew out, but I started it back up today to check to see where it was actually coming from, but no leak. Was it too full, I looked around the dipstick tube and it didn't look like any had come out there, but if the seal was bad wouldn't it sling fluid all of the time, or just when it was hot?

 

I'll guess that since you were breaking a cam in you had the motor out of the car and left the converter hanging in the trans? If so the front pump seal has/had a sag spot where the converter hung against is unsupported. If your lucky it is still soft enough that it has now re-formed to its original shape and has re-sealed, but usually it means you now get to pull the motor and trans back apart and put a new front pump seal in.

Was it overfull? How should we know, you're the one with the car and the trans dipstick. Check it. If it's full, then yes it was overfull, but it should have spit excess fluid out the vent up top. If it's low, it may now not be leaking because it doesn't have enough fluid and running the engine could damage the front pump.

 

It must have been a sag in it then, I did leave the torque on the trans for quite a while. I ran it again and no leaks. I don't think I had it overfull, but whatever. I went ahead and bought a new seal to try.
