As far as getting beat by a foxbody... Either it wasnt stock and would be something you shouldnt mess with, you really really cannot drive (yes even with an automatic), or your just making it up.

OK - I have read threw this post and I got a question or 2. SOmeone set me streight. The trany Guy who Built my Trany after it went out told me I should ALWAYS leave the Line in Low 1. He said that Locked all the clutches in place and instead of using only a few it used them all when I launched. I also spoke with the PC programer when he programed the car and said to let the Trany shift itself! He said you wont do it anny better than the PC does. NOW I got a Bud who always races in D and last week he blew his trany! He lost 3/4 (or D/OD) but the 1st and 2nd gears are fine. It seems like the fact he was NOT starting off in low 1 and that he blew the top 2 but dident hurt the bottom 2 gears proves that thewre is a benifit to starting in Low 1? I am no expert and I am sorry if this is old to you BUT I am just trying to understand how you ahould lauch, why is that the best place & what happens with the clutches when you do? I guess whats got me stumped is the Trany Builder (who has a great rep for knowing his stuff) told me to ALWAYS launch in low 1? Can someone explain the whole cluch thing to me again please? Thanks, Lata, Ark

I never claimed to be able to shift better than the Trany. Forget about who shifts better or worse. Can anyone tell me why it is or is NOT safer (stronger) to start off in first? DOes having it in first lock all the clutches up like I was told? Thats the part I am not understanding. I know the Trany can shift itself better than I can. Thanks for the reply. Lata, ark

This is also why in trucks they shift from OD to D when towing. Yes its an electronic Trans and is only going to shift to its liking unless otherwise altered by the abuser (shift kit, programmer), but its much better to run through the gears rather than leave it in OD and go to work with it.

In manual 1st the LO/REV clutch is applied, and the LO/ROLLER clutch is holding. In 2,D or OD the LO/REV clutch is not applied.
The OVERRUN clutch is applied in all positions expect OD, this provides engine braking.
This is from the ATSG 4L60E manual.

Okay, when you're in manual first, you have 2 more clutch sets applied than when you're in 1st gear with the shifter in OD. The Lo/Reverse clutch set is applied for added strength, and the Overrun clutch set is applied to provide engine braking. So basically, being in manual first and accelerating, you only have one more clutch set providing strength.
As for the other gears, the same clutches are applied no matter where the shifter handle is, with the exception of the Overrun clutches, which again, are only there to provide engine braking.
Hope that clears up some of your questions.

SO it seems like BY trany Builder was correct then and its safer/stronger (as far as clutches go) to start off on LOW 1. Thats what he told me BUT I never got an explination as clearly as yours just was. Thank you. Ark

Boy is their a lot of slamming going on here........
Manual shifting will not do anything because all you do is hold the gear longer than you should, and when you move the stick it lets the tranny shift. You dont move anything but a stick. If you want fast down shift push the trailer button if you have a truck that will help. If you have a sports car get it tuned........... A trans go will help check out e-bay for the best deals so for........

I have had the trans-go shift kit in a 4l60e and I think that it's a waste unless you're getting the car tuned-the torque management really gets irritated from the kit and a high stall converter(mine was an st4000). I manually shifted my bolt on 99 a4 to a 12.01-the car was untuned and wouldn't shift on its own for crap. I wouldn't call it power shifting, thats a stick thing

Well the reason peaople like to race starting in first low 1 is to ensure they are locked in low one. I have seen times when the tranny seams to be in 2nd gear not in first when taking off. I like to drag in low one, and when I am moving I nock it up and let the tranny do the shifting for me. The reason people loose gears is because of to much slipage. If you run your stuff hard get a trans-go shift kit it will hold the bands tight so you dont slip. GM makes their tranny good for 80 year old ladys to drive and 18 year old kids. Its just that all day, all year long hard shifting under wot will wair your tranny out..........my 2-3 went with 18000 miles under it. It was just worn out, not broke but worn out. I hit it hard every day and I am pushing 100 hp over stock...... hope this helps

I should take a video 'manual shifting' at wot, if i waited untill the tac read 6000-6100 to shift it'll hit the limiter almost every time, every gear. especially 2-3 its slower to react.
Gwcrim, fast and consistant cars can use autos. Many cars equipped with Pglides can make 7 second passes with less maintence than a manual.

This is not A3/4 vs. M5/6 Topic, that was debated before!!
SmokingWS6, I would think if your waiting on the stock to read rpms to shift, thats part of the problem w/ the RL. Its slow! And if you realized this you could always shift when the stock slow POS Tach reaches around 5800 instead of 6000.
I will say I dont agree with the reasoning that its ok to manually shift the A4 due to better clutch strength. If in fact, which it seems to be, there are more clutches engaged when locking into 1st, then I could see using 1st at the line, then going to D after that, but for me the risk of hitting the RL isnt worth it, I'm not worthy
With that, it sure would be nice for some sponsors to hop in threads like this where the professional who builds trans for a living can offer input, maybe one did and I missed it. I wouldnt consider it pimping their product, just a good reliable source of info! Any trans building sponsor feel like chiming in????

Earlier in the thread ...
What I was sayin' waaaaaay earlier in this thread is that if I break traction in first gear when launching and have to feather out of it, I don't worry about it hitting second gear and screwing my launch even worse. You can launch in 1st gear and still let the computer shift for you if you shift it just right ... just a technique that works best for me and is consisitent for me. If you hav edrag radials and can nail it everytime and get a good hook everytime, then, launching is 3rd is best, of course.

The way I do it is this:
In the water box I put it in drive and warm the tires until the trans shifts into 2nd then let it come out of the water and select drive to light the pre-stage lights.This allows you to slip it into N which keeps the trans cooler and allows you to hold it there until the other car is pre-staged then bump it into getting the stage lights on. At that point I shift into 3rd which with 3:42 gears it will be ok to go thru the ET lights and not shift into OD in the MPH traps,which will slow you down a little.
Do what you like,but this works for me.
