I have a 2010 Equinox.- Transmission or Catalytic converter?
Every since I bought this car 6 months ago, it has been one headache after another. The most important one is I have brought the car in to the dealer to whom I purchase it from and to the Chevrolet dealer complaining about performance issues. It is sluggish, and jerks alttle, both places have said, there is nothing wrong with it. Today I received a letter from Chevrolet Headquarters,, stating a catalytic converter malfunction on these cars. Would this malfunction imitate what I thought is a transmission problem? The jerking around and feels like it isn't accelerating?
Have the dealer perform an exhaust system back pressure test. They'll remove the upstream oxygen sensor and install a pressure gauge in the oxygen sensor hole. With the engine running they'll see if you have a clogged catalytic converter if the exhaust system back pressure is excessive. If that's what is going on, since you're out of warranty, go to a reputable muffler shop and get a universal catalytic converter as a replacement. They're much cheaper but just as good. I've had a universal converter on my '00 Grand Prix since December of 2013 with no issues. Now if the notice you got from Chevrolet is a RECALL notice, take it with you to the dealer and let them give you a new catalytic converter for free. HTH. -Jim
