Why did you adjust the bands to begin with? Were you having a shifting problem? Adjusting the bands is NOT part of routine maintenance. The bands are normally only adjusted at the time of rebuild. Was the transmission shifting normally BEFORE you adjusted the bands?
Everybody's "snug" is not the same. Try readjusting the OD band again. Tighten to 10 lb/ft, back off EXACTLY 2 turns, then WHILE HOLDING THE ADJUSTMENT BOLT TO PREVENT IT FROM TURNING, tighten the locking nut to about 35 to 40 lb/ft. (This one can just be good and snug with a medium sized wrench). Check to be sure that the modulator valve is NOT leaking. (No fluid in the vacuum line). Check to be sure that the vacuum line going to the modulator valve is in good condition and has a good vacuum on it. Also double check your shift linkage to be sure that it is adjusted correctly.
