13' R-SPEC holding gear too long over revving engine.

[T_D_Diggs]

I was merging onto the highway. And punched it. The car hesitated for a second then took off like a bat out of hell. All the way to Redline. Then all of a sudden it just would not shift. I had to let off the throttle before it would shift.
It over revved the car. And again would not shift until I let off the throttle.
Car was in automatic mode with esc on.
This has happened a few times now. Anybody else experienced this?
Sorry if there is already a thread on this. I on my phone in Costa Rica. So the search function doesn't work. This happened again the day I left home.

 

[T_D_Diggs]

Has happened on the 1-2 shift. A 2-3 shift and once on a 4-5 shift.

I had it happen to me here and there, won't shift and sits at 7000 rpm until I let off the gas

 

[T_D_Diggs]

Yes exactly. I at least feel a little better that it's not just me. Might just be in the character of the car and not an actual mechanical issue.

Anybody else?

 

[FastDEW1]

Never happened on my 2014.

 

[dmitriylm]

Every time I've romped on my 4.6 the transmission upshifted near redline. I've yet to see it hold but I've only had the car for a few months.

 

[T_D_Diggs]

Yeah I've owned mine since November of 2013. And it's only happened maybe 4-5 times. So it's not very frequent. But it's been on my mind

 

[Sal Collaziano]

Does it "over-rev" or "hold the rev"?

 

[FastDEW1]

It shouldn't do that. It should shift. This is not a calibration issue but more likely something wrong.

 

[T_D_Diggs]

Does it "over-rev" or "hold the rev"?

I Don't keep my foot in it long enough to know how high it will Rev. But I saw close to 7200rpm before I let out of it on one occasion. I have it going in when I get back to Canada and will have them look at it.

Sits right at red line... 5 seconds maybe

My brand new 2014 just did it from the first to second shift. I also saw 7200 and backed out of the throttle and it shifted

 

[T_D_Diggs]

Had to reschedule my car at the stealership. It's now throwing itself out of gear when I floor the throttle at a rolling start. I have to let the revs come back down to under 2500 before it will grab a gear again

 

[T_D_Diggs]

They suspect they may need to reflash the tranny programming as its not slipping or shifting hard.

 

[amartz]

I don't see that being tranny programming. When mine started to take way too long to grab the next gear, with an accompanying jump in rpms during the shift, I wound up getting a new transmission, under warranty.

If that's the case then that's the case. But I will let them do their typical run through every possibility before actually dealing with the problem.

Update: They did a reflash and it's been good since.

I'm glad to hear it! Thank you for the update...
