Exactly what was wrong with my 05 impala after changing the transmission fluid at 75,000 miles. No one could figure it out and no one would listen to me since I am a girl. I had the exact same problem with my 2002 Pontiac Grand Prix SE. I finally found a transmission guy who would listen to me...changed the solenoid...problem fixed! He asked me how I knew what it was...I told him I had that problem before. He thanked me because he had the same problem with another of his clients' vehicles and couldn't figure it out. Ha! We aren't all oblivious at everything carwise!

Was that a question or answer?....................Been married 22 years , working on cars for about thirty , and I'm glad my wife knows more about her car than I do 'cause it makes ignoring it 'til it breaks so much easier when I know it's not a safety item (brakes/steering/lights)!.....HA!........uhm..I think.
