RZB1992 Posted July 24, 2009 Report Share Posted July 24, 2009 This has happened to me twice now. Out of nowhere, my Intrigue's engine has this very different sound to it, and the transmission starts shifting really hard. It starts up fine, and did everything like normal, but then once you listen to the engine, or start driving and feel the tranny shifting, you know something's wrong. The transmission shifts as if there's almost no fluid in it. Tranny fluid is fine, and the symptoms went away by shutting the car off, turning to the on position 3x and then starting it again, but I don't know why it's doing this. I'm thinking some kind of a sensor going bad?? Anyone have any ideas??? Quote Link to comment Share on other sites More sharing options...
DavidHowell3633 Posted July 25, 2009 Report Share Posted July 25, 2009 Can you describe "weird"? Quote Link to comment Share on other sites More sharing options...
RZB1992 Posted July 26, 2009 Author Report Share Posted July 26, 2009 It's as if the engine has a deeper sound. Quote Link to comment Share on other sites More sharing options...
DavidHowell3633 Posted July 27, 2009 Report Share Posted July 27, 2009 No idea what this might be. But, you might check the vacuum hose that runs to the transmission. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted July 27, 2009 Report Share Posted July 27, 2009 if this is an 01 intrigue... it has a 4t65e, and will not have a vacuum modulator. you should probably do a pan drop and change the filter and fluid to see if that benefits you. is the check engine light on?

White93z34 Posted July 27, 2009 Report Share Posted July 27, 2009 almost sounds like the TQ is staying locked. could be a sign of bad things to come. Quote Link to comment Share on other sites More sharing options...

Ever since that happened I haven't had it occur again, and it runs, drives and shifts fine now. Like I said, just out of no where, it randomly happened. I don't know if it was maybe a computer thing or a bad sensor... I don't recall doing anything different while driving or starting it the 2x this happened.

White93z34 Posted July 28, 2009 Report Share Posted July 28, 2009 IIRC when a 4t65e gets the TQ stuck on, it will ramp up line pressure to maximum to, in theory break a suck TCC free. Quote Link to comment Share on other sites More sharing options...
