Goes to the red line and doesn't shift

akreidie1 · 09-19-2009, 09:20 PM

When I put the car either on s or c mode and presss the gas full when it's on 1st it sometimes over revs once then shifts really hard to second, it ussually happens when the ground is not very even, anyone have the same problem?

When "c" mode you cannot start off in 1st. It only starts off in 2nd. In "s" mode it will start off in 1st.

I think you might want to have that checked. when i floor mine in s mode it always shifts right at redline and its pretty smooth going into second and beyond, but I would never floor it on uneven pavement.

gsrjc · 09-19-2009, 10:45 PM

yeah, you should get that checked out

Say the road is flat and suddenly there's a little hill at aroun10 degrees and I floor it would stall a little on 1st before it goes to 2nd

Is ur esp on?? Thats probabyly why, its trying to grip but can't at that moment, after a second eventually it'll grip thats why ur getting that stall(lag). imo

I have hit the rev limiter a few times in sport mode in first. Probably 3-4 times in 19000km.

If he is going WOT, then it will go back to 1st even in C mode...at least it is supposed to.

This has happened to me too on S mode

and always on 1st

dmyrick · 09-20-2009, 04:25 PM

maybe it hasn't happened to me because when i floor it i kind of roll into the throttle a little, so i don't do burnout's

This happend to me the other day as well. Getting onto the highway I got into the throttle pretty good in S mode, ESP ON, as it reached redline it felt like it over reved, throttle cut off kicked in, lag, then boom hard shift into 2nd. Did not feel normal at all, but I think REDSRT is right, I think the ESP was kicking in and just throwing the timing off. In reality what probably happend was I lost traction, ESP kicked in causing the lag (which happend to be right at the top of the RPMs), then a hard shift into 2nd.

Me as well. Seems like when there is some unpredictable change in the road like a hill or a dip, the engiene hits the limiter before the transmission expects it.

This was discussed once before.

Happened to me a few times on 1st gear at WOT.

This has happened to me once. Something happens at that split second where you over rev and the rev limiter kicks in and bounce back then it shift. This is why you feel the hard shift. Because for a split second your car stalls (rev limiter) then kicks back up then it shifts to second.

Sort of like when you are going to redline let go of the gas (so it doesn't shift) and hop on the pedal (no more than 1 second) and you will get a jerk.

That's what it seems like it is happening.

I would say maybe you need a flash but this happened to me after a new flash I had. But like you said it was when I was going up hill.

I know our cars have a position sensor (it recognizes when we go downhill or uphill) so I am guessing it has to do with that.

Nothing really you can do unless you can constantly replicate it.

By the way on mine it wasn't the ESP. The ESP has never kicked in when that happened. I don't know about you guys I mean 450 VS 268 is a huge difference

+1

C or S doesn't matter. It starts off in second but if it feels the throttle is being pressed hard it will automatically kick in to 1st.

Put it in C and do full throttle it will start off in 1st.

If you are in "C", you can down click with the left paddle to first before you take off. It's a neat feature for the "C" lovers.
