What are the symptoms of a bad modulator valve?


Asked by Jul 04, 2015 at 02:11 PM about the 1992 Chevrolet Lumina 4 Dr STD Sedan

Question type: Maintenance & Repair

1 Answer


On the transmission? Late or no upshifts. Clouds of grey smoke from the tailpipe. Losing transmission fluid with no visible leaking. But I don't believe that a '92 model has one. It's electronic. HTH. -Jim
