Last week i replaced all 3 O-rings on the Kickdown Solenoid because it was full of Trans. fluid.Now i think it may be coming from the thing above it.It is about 2" in Dia. with 3 small bolts.One is a nut with a small slotted screw in the center for some kind of adjustment.What could be leaking? I will try to send a photo.

The device you're referring to is the secondary pump, It's purpose is to enable push starts.
The secondary pump was discontinued in about 1992 and the site is now covered with a block off plate.
Order the plate and gasket from your local dealer. You'll need a 10mm wrench and a 5mm allen (1/4" drive is preferred) and a lot of patience.
Good luck Mike

How much trans fluid will i lose,i want to be prepared?

Local indy said that they replace the O ring and do not use a plate.What is best?
