First thing is to make sure the trans fluid is at the full mark

I'm told this is probably a solenoid of some kind - if outside the trans casing, reasonable to replace but if inside the transmission, no shop will open and replace, they want to put in a rebuilt transmissioin for about $3500-$4000. With 185000 miles on mine (and i love it!) guess i'll wait for the next Lucerne and see. CarefulDriverJim
