View Full Version : Stall shifting sucks..

Just got a tune after the install of my 3600 stall and i am not very impressed. When the car is in drive and you get on it, the rpms go up and then they feel like they level off before it shifts and kinda does the same thing in second but not as bad. It only does this when the car is in drive and not when manually shifting. Could this be the tune or is my tranny on its way out?

Ever driven a stalled car before?

You get used to it. My car goes 3000rpms (shift) 2900rpms... speed still increasing... (shift) 2800 rpms.... around 42mph now (shift 4th) 2750 rpms.... lol

4400 stall. The rpms might not go down but your relative speed per rpm DOES go up. It's just how stalled cars drive. When it locks up (54 mph in my case) rpm drops to actual... so it's all good.

I don't mean the rpms aren't dropping enough that's not what feels odd its when you get on it in first it almost feels like it shifts early cuz right before it shifts it seems like it loses all the torque and then shifts

Sounds like a lot of Torque Management (pulls timing right before and during the shift).

So the torque management might need adjusted when the car is in drive because if I manually shift it it feels 100 times stronger then if I leave it in drive

Go have a talk with your Tuner and let him know what you think, maybe he can fix it so you like it. I just had my Tune adjusted and i can live with it. just a thought.

You need to install a tranpro shift kit and then have the trans tuned. It will shift hard and bark the rear tires. Def sounds like tork management with the long delayed shift.

Alright guess I'll have to give him a call I might just have to wait until my cam goes in so I wont have to pay for additional dyno time though. Thanks for all the responses!!!

Are you in D (3rd) or OD (4th)

3rd is what you need to leave it in until you get enough speed to need 4th

I had a 228r with a custom built 3000 stall and that bitch was nasty and it was running on a fucking mail order tune. I had head work and shift kit with all the other goodies too as well

You need to delete the torque management.

It's In od but the 3-4 shift is fine its the 1-2 shift that's bad

Sounds like it needs rid of the torque management and a bump in line pressure...

01-21-2012, 07:40 PM
Well I'm gonna give my tune a call and see what he says. Thanks for the ideas.

A stalled auto isnt suposed to have the same shift firmness as stock TC. It feels more like a easy shift. Before I put my stall in and got a tune I had the line pressure jacked up and the tires would bark but come to find out my "NEW" tuner told me thats no good. To much line pressure is not good for the trans and fully deleting torque managment is no good either. So I wouldnt go messing with the line pressure or deleting TM because your upset theres no tire chirp.

01wss6
01-21-2012, 11:10 PM
I'm not upset about the tire chip that doesn't matter to me I just don't think the 1-2 shift is right. I know the firmness won't be as firm as stock. I just don't think the shift is right. Its kinda hard to explain when I'm in drive and take off from a stop and accelerate hard the car rpms jump like there supposed to but it reaches a point where it feels like quits pulling. (So when I take off I'm back in my seat and then right before it shifts I'm not back in my seat.) Then the car will be like this for a second and then shift. I'm just not sure if its tuning or not. This only happens when I do it in drive not when I manually shift.

Hmmm. Talk to your tuner about it and see what you guys can come up with. Let us know what you find. Wish I could be of more help.

I will. Might have to wait until I get my cam in so I can get it all done at once. Thanks for the help!!

You definitely need to get it tuned could cause trans damage and it depends on who done the trans on whether they want the line pressure turned up or not and definitely turn off torque management it should shift firm and fast in ever gear

caviness
01-22-2012, 02:22 AM
Oh if it's stock trans you might want to leave some torque management in it for sure. And did you put the shift kit in when you did the converter or not that will help.

I have the tm of on mine but it's a built trans

Definite tuning issue! I have a 3400 with a built trans so were pretty close on spec there. It does NOT feel like a normal auto car at all, but what your describing is no right. During normal driving it will do the whole leveling off thing as it shifts... almost feels like its slowing down and then it shifts. If your above 70% throttle or so it should hit pretty hard. Mine with 2.73's will bark 2nd at 60mph everytime and in inclimate weather will occassionally break loose at 3200 or 3400 rpm 1-2 shifts. Granted I make 400hp, it still would bark second when I was making 340ish hp.

Well at least its probably not my tranny about to take a dump on me lmao. Like I said if feels amazing when I manually go through the gears but when its in drive and I get on it, it doesn't feel right at all.

Well talked to the tuner today and he said he reduced the torque management but didn't delete it. So when I get it tuned again should it be deleted or just reduced more?

Tainted
01-23-2012, 11:26 PM
Delete it

01wss6
01-23-2012, 11:30 PM
So when he does it there should be no torque management? And also kinda off topic but am getting a cam put in and that will need tuned. Is there anything specific I need to make sure he tunes for so I won't have to have it done again?

LS1121
01-24-2012, 01:36 AM
Yes...after you put the cam in tell him what it is and he will do the rest.

sounds like you need to cut the shift times down as well. seems like when the commanded shift comes the trans is lagging to get you into the next gear which is why your feeling that lag. a shift kit will definitly help make your trans shift better and last longer. I recommend the transgo HD2 kit for the 4l60e.

I wouldnt delete it. Take some out but not all.

I'll just see what he has to say when it gets tuned for the cam. Thanks for the info everyone!

A Vig3600 is actually a good bit higher stall than 3600. I believe the rate them based on the LT1 so that is actually a fairly sloppy feeling 4100ish stall converter and if it's in a stock transmission it will probably feel pretty loose. Proper tuning can sure help it out though.

What gears do you have out back?

Are you having it tuned by a shop or and individual that does tuning for people? Just curious really. I don't mind looking at your tune if he needs help with it.

Look at this and compare to what your car is doing......

The cars fine with light throttle but when its anything more then light throttle the rpms don't shoot up the car feels flat and then shifts so it seems like from what everyone's been saying the torque management needs deleted and maybe the shift points adjusted. I called my tuner and he said he reduced It but didnt delete it. It is shop tuning it and I have stock 323s

TXCAMSS

I'd be tempted to have him delete all the TM to see if the problem is resolved. Those 3.23 gears with that loose converter will feel mushy, but not like you are describing. It should blow the tires off under hard acceleration IMO. I'm leaning towards an internal problem if removing all TM doesn't make a big difference.

Do you have any friends that have a 4000-4400 stall that you could drive as a comparison?

Just a thought

01wss6
01-27-2012, 12:58 PM
I don't have any friends with a stalled car but I'm thinking its the tuning too because when I manually shift it its great just when its in drive and with hard acceleration the car seems flat.

Hey dude, sounds like it needs some tune love. I had a couple tries with a guy that tunes for guys and it was a waste of time and money. So make sure this tuner that does this, is gonna take care of you.

For my problems, I went to a professional and told the tuner at a very reputable shop this go around, to drive the car from his house to the shop so he could get an idea of what was going on. After a couple of weeks the shifts at all speeds etc were perfected. I almost sold the car and gave up on the damn thing because I was so sick of shity tunes...

Well when I called he said he would take a look at the tune and also said he took some of the torque management out but didn't delete it so I guess I'll just have him delete it

This is just the way high stalls are. They take the positive feel away at low speeds. It is just one of those sacrifices you make and try to get used to. I manually shift mine at about 3k to get the positive feel back.
