Not sure whether to put this in suspension, transmission or engine, so I'll try all and see which one gets some odd questions answered.
I've got a 2006 GP, automatic,with about 112000 miles on it. This problem has started only very recently. If I make a left turn, engine response is noticably decreased and the next couple of transmission upshifts are rough and clunky. This problem only happens when in LEFT turns and goes away immediately after hitting fourth gear or slowing down again. Right turns are unaffected. I have taken to accelerating up to the point of turning, coasting through the turn, and only accelerating after fully straightening out again. This helps some but doesn't fully alleviate the problem. I have no idea why left hand turns would be affecting engine power or shifting, but there it is, and it's a worriesome problem to have.
Any and all suggestions will be greatly appreciated.
