I had a nice surprise when I replaced my vacuum modulator (TH350) a couple of days ago due to late shifts........I dumped a couple of quarts of ATF on my driveway and myself. I can only assume I have a stuck modulator valve. Can anyone second that motion? Never had to replace one but read on older threads that there is a fix by very lightly sanding it and re-installing? PLEASE don't ask me to rebuild the tranny as at this point my license plate should read "MNY PIT" as my wife says.
