First time at the track

[35th-ANV-SS]

If the AT is not programmed to shift at 6100, then you will be faster if you manually shift it. My 1998 TA was quicker and had a higher MPH when I would manually shift the AT equipped, 2.73 rear diff car.

Went from 13.9-14.1 @ 99-100 to 13.6x - 14.0, 101-103.x.

I could time it so the shift happened just before the rev limiter kicked in (6200 stock).

Makes perfect sense. I'm a M6 so I am slower all together

ive had this argument many times before.....my car went faster down the track when i manually shifted....ive proven it time and time again...its not the same for every car though...it just depends on how your trans is actin....at wot, the car would hold the gears too long, and this was on a stock tune..

Exactly.

This is why you have to try any car different ways when you drive it, to see how it works best.

Try it by letting the slush box do its' own thing, then try it doing it your way, and see what works best!

Just a quick question, does GM have the Camaro shift at different points than the Firebird? My A4 shifts from 1st to 2nd at 5500 and from 2nd to drive at 5400. I tried to manually shift it and it was slower. However, I did let it shift on its own from 1st to 2nd and then put the shifter in 2nd and held it out till about 5700 and it shifted right before 6k and it got me about .05 of a second off my ET. When I tried to manually shift from 1st to 2nd it sort of took a split second longer to shift, like it was holding its self back. I see that they say max RPM is 5500.....but yeah I figured the rev limiter was 6200 or 6250 for the LS1s.

13.545 on its own vs 13.514 for manual 2nd to drive. Need a shift points stiffened upa nd raised......lol

bye bye rear end

It's kind of a crap shoot when it comes to the rear end. Mine is a H/C stick car with 140K miles on it, all I did was put the girdle on from summit @110K and had no problems so far, although I have the $$ put aside for a beefed up one when this one blows out. I know some people have blown them out on stock cars though.

OP if you put slicks on and go to the track a lot I would have the $$ saved up for a new rear end just in case.

Oh yea my next thing is to get a non catted y pipe with pacesetter LT's to finish my exhaust. Then a fast intake with throttle body and possibly either cold air or do ram air set up and i had planned for a 2500 stall since its my DD. But all this has been set off cuz i need to pay my speeding ticket haha

You will be really pissed with yourself if you get a 2500 rpm stall. get no less than a 3k stall.

I don't know for sure, but the shift points should be the same since it is the same engine/trans. And if you look, the redline is actually 6,000, at least on my car. Yellow starts at 5500. There is a delay when you do the manual shift, you have to anticipate that to get the shift where you want it. a .05 sec difference could easily be many things, so I don't see that as a difference. Now .2 or more, yeah.

Many here have really liked their AT cars once the torque management was removed from the PCM and line pressure increased; along with a stall, these make huge improvements on ETs.

Agreed. You wont even notice a 2500

Well, crap. There goes that idea.

Get a yank 3600 and dont look back!!! Makes an auto SO much more fun, maybe more fun than a manual. I miss my stalled auto.
