Rev light stall on AT

AngelNismo · 05-25-2015, 10:47 AM

I notice (all in D mode) that if I WOT from < 5 MPH the car picks up quite nicely all the way through, but there are some rare occasions when I WOT from > 20 MPH (or some cruise speed) and the rev light will suddenly come on, it will stall a bit somewhere pass 6K RPM, and then after a second seems to go into next gear; I assume since the rev meter suddenly drops and picks up again.

Any ideas on this?

That should only happen if you have your auto in manual mode, and are shifting it too late. If this is occurring while solely in D mode, I would consult the dealer.

Then again I should say sometimes when you are trying to just go flat out iirc the rev limiter light does blink but the shifts are pretty seamless. I know that I have been in manual mode and missed a shift, or wanted more from the engine, and it was just like nu-uh buh bye, and it does cut power drastically when the rev light comes on, but that is only ever in manual mode. If you are experiencing anything significant between shifts when fully automatic you should get it checked out.. Is the car new/used...maybe it has been tuned and can be corrected.

The car was bought new, I'm going to bring it to the dealer and have it checked out I think there is an issue, as this was happening in automatic mode.

Let off the throttle while past 6k for a second and it'll shift.

So it's normal that if I'm in automatic mode and the car is WOT for it to stall like that?

I have had this same issue while in "D" it seems the ECU is trying to process the quick acceleration and almost seems buggy at times..

It happens sometimes when I am driving use the paddle shifters and suddenly pop it in "D" the ECU acts goofy afterwards with how it shifts and at what RPM, because it's learned your driving with the shifters (There was also a thread explaining an issue similar to this however I wasnt able to locate it).

I'm positive someone can explain it significantly better than I, but thats the jist of my perspective. I pretty must just drive with the shifters unless in traffic.

wtf is "D" mode?

That would sux if that's just how it is, anyway I made an appointment for Thursday morning, I'll keep this thread updated on the results, the transmission specialist will take a look at it.

Never hurts to double check

obviously lol

I never use it. only manual mode.

also the ECU learns the way you drive so if you use manual a lot and then switch to D it'll try and replicate how you shift typically.

only thing I have ever encountered is a throttle blip sometimes when shifting from 4th to 5th. it'll rev up like 200-300 rpm's sometimes.

solution: drive it in manual mode all the time. trust me I never see any issues aside from the throttle blip if you can call that an issue really lol

Thanks Array appreciate that, really hope it's not that the ECU is "slow" at times

also you can get the tranny tuned with uprev to shift harder and faster
