turbo 350 blowing fluid out

[A61Belair]

turbo 350 manual rev valve body, transbrake and 5500 convertor. has a deep pan, and yes it has the extension on the filter. it blows fluid out the vent when you get on it. its not overfilled ,because it blows fluid out until the trans starts to slip

ANY IDEAS?

you have a fluid leak somewhere in the tranny. When you drive , its bleeding fluid in the pan and going out the vent.

Have you checked to make sure the case has not cracked?

Could be the gasket or o-ring on the front pump.
