My C4 has started shifting up and down until I get to about 50 mph. A friend suggested changing the modulator and said I could expect a little fluid to come out. I took off the old modulator and about 3 quarts of fluid came out. Is this the normal amount that should come out? I have stopped working on the trans until I get more info from some of you with more knowledge. Trans was rebuilt about a year ago and a shift kit was installed. Car is a 1965 Galaxie 500 with a basically stock 289 (added aluminum intake a 4 bbl). Thanks

If you had the front of the car jacked up it is normal for lots of fluid to come out.
Don't forget the modulator pin.

Yes the front of the car was jacked up. Thanks
