[ANSWERED] Camaro SS No-Lift Shift feature questions

First of all, I’m glad you Camaro owners are using all of the functions of the car, including No-lift Shifting. Our engineering team is always looking for the best ways to combine performance and technology to improve the Camaro driving experience. This new “ask Al” forum seems like the perfect place to go further into detail on some of the features that may not get the proper explanation in the Press Releases or media outlets. I’d like to explain what the feature is, first, then explain how to use it on your Camaro. The Camaro has actually had ‘No-lift Shift’ since the 5th Generation. It is a feature that is intended for our drivers who want the performance feel of quick power shifting in our manual transmissions. The feature keeps the throttle at full open for both our boosted and non-boosted applications when passing through the Engine Over-speed Protection during a shift. In Engineering terms, when triggered, there is an immediate torque control, with fuel and spark, for a given period of time. Then, a predictive control takes over using the throttle to control torque. This allows the driver to take advantage of fast torque control for a short period of time (e.g. during the shift) without heating up or damaging the catalyst over time. To address the most common question about the feature, you should know that there are both enable RPM’s and target RPM’s for each transmission, which are different for each engine application on the Camaro. We’ve put together a table below to show enable and target RPM by engine. To perform a No-lift Shift, simply put the throttle to the floor (i.e. WOT), and keep it there. Once the tachometer reaches the enable RPM, you can depress the clutch and shift as quickly as you can, and you’ll notice the tach will go to your target RPM during the shift. For example, if you are driving a 2017 SS Manual, with your throttle pedal to the floor, and the tach above 5000 RPM, say 5100 RPM, you can quickly upshift without lifting your throttle foot. The tach will reach the target RPM, in this example 6400 RPM, but not flare to redline. You can quick shift at any time during this RPM range. By the way, in our 2.0T Camaro (RPO LTG), if you are performing a No-lift Shift sequence, you will notice that you don’t lose boost during shifting, as you would with normal shifting. This adds up to an improved lap time or quarter mile. Also, you need to have a minimum speed of 15 kph (9.3 mph). Attachment 906630 I would like to address a few of the specific comments with regard to No-lift Shifting. As I mentioned, the feature is on all 6th Generation Camaro Manual Transmissions, with the exception of the 2016 2.0T and V6. Those were added in Model Year 2017 and beyond. With regard to the effect of Mode selection on No-lift Shift, there is no difference between Tour/Sport/Track/Snow-Ice mode or PTM mode on the ability to perform the quick shifts. Most people either don’t keep the throttle to the floor, or don’t wait until they reach their Enable RPM before performing their shift. Both are required criteria to execute the No-lift shift feature. Lastly, the Enable and Target RPM is different for each engine application, and even within an application (as in the SS and SS 1LE). If you are having problems using the feature, give it a try as I’ve described in this response. It may seem counterintuitive to keep your throttle to the floor while shifting, and the V6 and SS target RPM’s seem close to redline, but trust that it works. It may just take some practice. Good luck with our No-lift shifting! I hope this response is helpful, and the type of information you were looking to see from the Camaro team. Until next time, Al O. |

That explains why the SS owners seem to go to red line while the 1LE seems to drop to the rpm for the next gear.
Thanks! |
No-lift shift is an awesome feature.

This is the kind of info we always get from Al.
I think it is the reason so many of us have such great trust in the Camaro team, and also, so much love for our Camaros. Show me another product that you purchase where you get to talk to the folks who design it, engineer it and build it. Thanks to Al, Tom, Mark, Jim(2), Ann, Rosanna and all the others who show up at our get togethers to talk with us about our mutual love of the Camaro. |
Awesome answer! I don't believe it was known that the 2016 turbos did not have this feature (generally speaking...
|
Very cool information and some insight on how the executed the feature!
Two things though: First, is that a typo for the target rpm on the LTG? 3400 seems real low Second, I have a MY16 LTG manual and can confirm that I have no lift shift. Target RPM seems to be 5300 when I shift from 5000-6000 rpm. however when I NLS below 5000 it seems to pull 700 rpm fairly consistently. *mind you I try to not stare dead at my tach when boogying down the road* |

Thanks Al! :thumb:
This would make a nice addition to the high-performance owner's manual supplement. |

To get this clear, this is how it works?
e.g. on SS -> 2nd Gear, reaching 5.500RPM -> Pressing the clutch while staying on full throttle, the RPM raises to a maximum of 6400RPM -> Going into 3rd Gear the active Rev Match get's the RPM to the optimum, so you can shift as fast as you can and release the clutch Am I right? Also: Is this feature included in european models? |
