Last weekend, the cel pops up during driving. There was a bit of traffic so I was mostly driving between 45-55mph. But strange problem is, prior to the cel light coming on, tranny feels like it's always on the highest gear at those speeds. So even when I gently tap on the throttle to pick up speed, the tranny appears to have to downshift each time before it moves. I'm just wondering if it's just me or does it suppose to drive this way. I feel like I have to hit the throttle harder for it to pick up speed.

It could be related. The only way to know is to read the codes.

I take it this is a major problem, no? When I reset the ecu, it runs normal for a little while. The problem Im having is the car hesitates when I accelerate.
