I'll call it a vibration but its not really that bad. It just started the past few days, may be I'm losing my mind but here is what is happeneing. I have the automatic and when it shifts the last time at about 50 mph or 55 mph the tach is at about 1500 rpm and I can feel a slight vibration in the steering wheel. It doesn't shack the steering wheel but I can feel a vibration that I don't have prior to this point. To better explain it, it would be like having a stick shift and being in a higher gear then the rpms can handle, the engine bogs and makes a little noise. I pushed the tow haul button and when I reached 55 mph where it usually gives me the little vibration, it wasn't there. When I am going faster then 60 mph or 65 mph, I don't get it. It the little vibration caused because it is shifting at a lower RPM or is it something else. Anyway now that I'm out of breath from all this typing, i would appreciate any suggestions anyone might have. Thanks BART
