No Lift Shifting...you doing it?

[Legend]

I've not done it...yet!

Though I would think it could save a tenth or two if you just held the gas to the wood and punch the clutch to shift!

Thoughts? Expereince?

Do you have to turn off everything to do this or leave TC on?

Help!

[blufin]

I tried it and the car didn't like it. It made a heavy clunk and the car bucked briefly. I heard that if the car has a stock tune it can't be done. Something about the computer cutting back fuel when it's done. I did it regularly on my 01 WS6 with good results, but not this one.

No problem at all shifting like that, my car likes it but it likes it better with TC off.

[Legend]

Times better doing this or about the same?

I realize it might only save a tenth or so.

Ah, the old powershift. I havn't tried it in my SS, but I used to do it in 73 Z28 with a Muncie close ratio 4 speed. Hitting second gear was wild!

The time you will gain is not worth the damage to the tranny you are doing.

Yep my 74 w/M-22 could handle it, haven't tried it yet in the new ride though

Done it to mine with no prob. Picked up a couple tenths.

Thanks...just punch the clutch and leave the gas to the floor? Was the TC and everything else off (otherwords, did you hold the "button" for 7 seconds)?

How was the hit in second and third?

I like the "couple tenths" you picked up too

If you don't know how to powershift I suggest you try it at very low speed first, before you make a thread on your damaged transmission lol

[will69camaro]

VERY TRUE. You have to be confident you're not going to mis-shift. No room for error. If you bang the wrong gear it's BAD news. Mechanical over-revs generally aren't good for engines and the speed drop through the transmission as it tries to pull down engine rpm generally ends poorly as well.

I did it however with stock shifter and a few times with the new MGW on this car.

STS and TCS off (TC button down for 7 seconds). Leave pedal on the floor and just work the clutch and shifter, fast is necessary to keep it off the limiter. Definitely not recommended unless you are VERY confident with shifting fast and precise.

In my 99 SS I used to do that the last couple runs of the night to try and set a best time. I haven't had an issue in the 2010. This TR6060 is a SMOOTH shifting transmission compared to the T56!

Powershifting would require no clutch as well based on what I know...whereas no lift shifting you are still using the clutch. At least that's my expereince...also, wouldnt you want this to be a the fasted rpms to allow the gear to "slide in"...not the slowest...or lowest speed as you suggested? Don't think you'd ever get it in gear going slow?

...and if I did dump the tranny doing this I highly doubt I'd be posting a thread about it! I'd fix it and learn...what do they say..."you have to pay to play"...been there, doing that!

Thanks...exactly the information I was looking for...much appreciated!

Anyone else?

[Unfair]

Umm, powershifting definitely does require you kicking the clutch bro, you heard wrong and please don't try that on your car at high rpm without the clutch!

I can powershift, and you can practice at low rpm so as not to kill your tranny if you mess up... you can do the exact same thing heading to 4k as you can heading to 6k. same effect less danger for practice.

If you're taching 6500 @ 80 MPH and you meant to throw it into 4th, but throw into 2nd....
