So I had my traction control off, threw it in Manual Mode, and Sport Mode.
Forgot I had it in manual, not just temporary manual/paddle shift mode
And my RPMs were about to redline and it just bounced off the rev limiter WHILE driving!
IT WAS INSANE, SOUNDS SO FREAKIN AWESOME, with my JoeZ Axle Back, but my heart sank with my car barely hitting 900 miles
my poor baby engine.
Have you guys 'accidentally' done this?

the damn tranny does shift too early, either in manual or auto mode. i'm trying to find out how i can go in a straight line, hit near redline and CHOOSE to shift myself instead of the damn computer taking over. i hate it right when i shift, and the tranny got to it before me and basically it upshifts two gears and then the power just lags.

The limiter is there for a reason.

Nothing should be wrong with the engine, right?

[QUOTE=AdvanSLF;8801652]so let me get this straight, what you're saying is you're approaching redline, and then it just jumped in a surge of power to hit the rev limiter?
NO IT WON'T JUST SHOOT IN SURGE OF POWER....i'm saying it'll bounced at the red line while still driving and won't shift by itself..
take off traction control and you get full manual mode.

Even with traction control "fully" off it will still upshift by itself near or at redline. Occasionally it'll hit and bounce off the rev limiter. If you are in auto mode in second gear and floor it, sometimes it'll do that once it hits the limiter in first gear, sounds really cool but that's about it. And there is no full manual in this car. It's to prevent idiots from damaging the motor. It is annoying for sure but once you realize this isn't a race car, it's actually quite awesome overall. Took me a lot of back and forth and driving other cars to finally realize that.

sorry to bring up and old thread, but just bought an Jan 2014 build IS350, and auto upshifts no matter what I do (i.e. traction control off and sports + mode)... anyone know if there is a firmware update for early model transmissions?

It's supposed to up shift when you hit the red line. You may get a little bounce in lower gears if your really on the gas and WANT it to max out ... but for the protection of the engine, it will auto-shift for you.

I've had it bounce off redline with traction control off in 1st on a rainy day. Other than 1st I can't seem to keep it from shifting for me. Throws me off a couple times because I end up skipping a gear when it shifts for me right before I click the paddle one more time.

PatrixUSA created this thread to chase down the answer. It does seem like it depends on the build date.
