Hi there ! I read the other day that I can control the shifts in my automatic V6 using 1,2,3 and D, to speed up faster. It is safe to do this? I don't want to mess the transmission.
I would not do that on a routine basis. If you want to improve your automatic shift points, you'd need a custom tune.
actually there is no real harm in manually shifting... it's not like the old days... the shifter is not physically doing the shifting, the computer still is doing it and will only shift when the computer decides it's safe...
but to answer the OP original question, no, it won't make you faster... chances are it will slow you down... as stlwagon pointed out get a tune... will vastly improve the crappy stock shifting... most tuners will actually allow you to firm the shifts up a bit more too...
yep get a tune, def firms the shift pts, some ppl claim a little chirp every now and then..i also found if you turn off your overdrive and turn your tcs off itll give you about 200 extra rpm to wind out, just dont forget to hit the od when you get up to speed

i dont agree with the others posts, not to say they are wrong but i noticed a difference in shifting myself, more so with a tune. When i was stock and i shifted myself it would allow me to not be so slugish at time
Example: if your going 55 mph try to floor it, i bet you it will take forever to get some gitty up, then try this again at 45 mph, you will feel a significant difference. Your going to want that feeling everytime you hit WOT. So if your going 55 and want to accelerate faster, hit the O/D button on the side of your shifter so that it says O/D off on your Dash. You'll notice a slight increase in RPMS right when you do that because your now in 4th not 5th, and then downshift from D to 3 and floor it and you will pick up faster.
With a tune im now able to shift at 6500 RPMS but if i keep it in Drive it will shift at around 4900 RPMS and often be sluggish, I have manually shifted for almost 40,000 Miles and have had no engine problems except for my electronic throttle body which was quickly fixed and some other electrical problems, nothing that has resulted from my Manual Shifting.

just be careful, my friend used to do it in her pontiac, went from 3rd missed D and Nuetral, and guess what, hit reverse by accident doing 60...OOOPS good bye tranny...

I assumed the OP was talking about going faster from a dead stop by upshifting manually... not downshifting... the stock tune is HORRIBLE for downshifting... ugh...

the computer actually controls the shifts... it won't shift unless it thinks it's safe... like the guy who was complaining because he couldn't do a neutral drop/slam in the rental car... the computer actually waits for the RPMs to come down to a safe range before it will actually put the car in gear...

yea i tried doin the neutral drop, it actually works if you do the N to 1st but it sits for a few seconds bouncing off the rev limiter as if i had a turbo or something, it sounds nice but im sure it harms something and launching at 4500 RPMS jus causes my tires to spin like a mad man

say what you will about the computer, you cant trust it, her car schreeched to a halt with grinding sounds beneath us and you couldnt get the car to move, the next week, we helped her dad buy and install a new tranny, saw the same thing workin on HMMV's in the Army, dont trust your computer

We were talking about S197 5R55S automatics... no idea on anything else...
Our Trannys Are Supposed To be A Lil Tougher Than That....They Are THe Same Ones On THe Gt And Rated For More HP.....TCI Actually Sells A Shift Kit For It As Well As A Ratchet Shifter To Allow For You To Shift The Tranny One Gear At A Time......I Would Upshift The Tranny Manual But As For A Down Shift I Wouldnt Suggest That.....Instead Of a Nice Smooth Upshift You Are Slamming The Weight of the car into the driveline Causeing A Harsh Backlash Through The System...Not The Greatest Thing In The World For Your Car. What I Do When I Go To The track Is I Manuel Upshift From First To Drive And When I Have To Slow Down Just Leave It In Drive and Let It Shift Itself Down..

Trannys are not exactly the same between the V6 and the GT... V6 is not quite as robust... smaller clutch back and I think possible the shafts... could be wrong.. been a LONG time...
No issue down shifting... Remember even though you are manually moving the shifter the computer is still the one actually doing the shifting and won't shift until the RPMs are in a reasonable range...
Trust me get a tune it will solve your crappy shift points and you will have great throttle response too : Sorry Old Thread
