Ok guys,

I tried the search on this but couldn't find anything on this particular issue.

This morning is heavy traffic some dork almost rear-ended me, actually skidding up behind me. Traffic in front of me started to flow so I floored it to avoid the rear-end collision. The engine revved to about 4500 rpm, I backed off for a moment and accelerated again only to notice that the rpms were increasing but the speed was not. I had to back off on the gas for a few seconds then hit the gas and the car started to accelerate again. My G has only 3000 miles on it, and 4500 rpm is not unreasonable. Is this the VDC doing this?

 

Did you see the slip light/have time to look for it?

 

No, I was focused on the rpms and the traffic in front of me. No dash light caught my attention.

 

It might be the cold tires and VDC interaction combo.

 

The 5AT has a notorius pause if it senses you back of the throttle at a high rpm. I'd call it a glitch since it can leave a driver rather unsettled at high rpm moments. It's normal and an ECU reset can do wonders for tranny reaction times and I believe eliminates the long pause in such situations as described above.

 

Yes, this is normal operation of the 5AT and most any other late model automatic transmission. The tranny shift programming uses a thing call "torque management" to reduce shock and stress on the tranny. What you are encountering is a downside in the torque management system.

 

Thank you all for your responses. I took my G to the dealer today and they also told me it was normal, but couldn't elaborate on why. I get much better information from all of you.

Thanks again.

 

I would reset your ECU and then take a drive...you'll notice the transmission should be more decisive in general and would help you avoid it from happening again.

 

how do u reset the ecu?
