Hey, Past two days I have noticed my car lags shifting only from 2nd - 3rd gear. It doesn't feel like a slip to me but I could be wrong, it only occurs at medium - hard throttle. The rpms will pick up for a second or so like your revving it in neutral then it will suddenly catch the next gear. Trans oil is perfect and doesn't smell burnt or so. When applying only light throttle, it behaves normal. I'm leaning towards the TPS, my plugs - leads and fuel filter were changed about 1 month ago. Anybody else experience this or have any opinions, just hope it's not my box on the way out. Thanks in advance.
