Stalling?
 

Ok my G/f was driving to my house a week ago. She came up to the first stop light went to slow down and her car bogged and stalled to a stop(engine stopped car). This happened for the next three lights, and when she went to slow down for a turning car(on a major highway). She jumped on the Interstate and it hadn't happened for the rest of the day. A day or two later it happened again for a few lights. Then another day or two went by, I was with her we were leaving the mall parking garage. When she went to come to a stop the tranny acted confused bogged and stalled the car. I know her tranny is really slipping, and cooked like a thanksgiving turkey gone bad...But do you think it was her Tranny or could this be something else? We want to get the tranny rebuilt at a local race shop on friday, And was going to get everything upgraded for nitrous use, then also a shift kit and a 3200 stall. Will the stall cause any problems? I searched on this stalling issue and somebody said their high stall caused a Stalling issue and needed a tune. I don't have the money for the tune so should I not do a stall?

Thank you

New addition, I talked to her on the phone, and tonight she was driving slow through a parking lot 20-25mph. And it felt as if it was trying to change gears. It went to stall (It bogged) she gassed it then it changed gears and was fine.

Re: Stalling?
 

The torque converter isn't unlocking right. Probably a sticking valve from the gunk of the fried trans. If the tranny is toast tell her to stop driving it 'till it's fixed.

Re: Stalling?
 

It's her Daily Driver, And her parents are rebuilding the tranny. Thats why it hasn't happened, So if theres more damage done we don't really care except to say we told you so. We just want to make sure its not another problem arising.

Re: Stalling?
 

New update:
The rebuild should happen next weekend, What do you think about the stall and shift kit?

Re: Stalling?
 

Since it's her only daily driver and she obviously can't go without a car or else she wouldn't be driving this one now... I'd think twice about the 3200 stall speed. Adding the shift kit should be fine as should a milder stall speed.

If she has driven a 3200 stall car before and her parents don't mind fixing a broken car go for it. But turning a daily driver in to a race car that gets driven daily is a tricky proposition. Don't get upset if you start to break stuff when you start beating on a car that is no longer stock.

That's my $.02 that you asked for. :)

Re: Stalling?
 

I was always told with ls1's you do atleast a 3200 stall or theres no reason doing one at all.
Everyone can say something will break from building this tranny, but then they don't say what. Why?
If you have experience come in tell me whats going to happen and why. If not don't say somethings going to break, if its never happened to you. Just looking for a more in depth responce.

Give me your knowledge, I can only grow smarter from the whole story, not pieces. And Please don't give me hearsay. Thank you for all your Responces.

My Vig stalls close to 3800 and I needed a tune after the install - car wanted to die at low speeds (parking lots, etc) so ended up getting my idle speed increased, upped the line pressure, torque management erased, etc. I recommend a trans cooler if you go with a higher stall too. Haven't broken anything, but took a week or so to get used to the higher stall. Don't know what year the car is, TM is more of a problem on 01/02 cars. Give some sponsors a call - I'm sure they'll be glad to answer all your questions. I have a buddy with an 02 and 3000 stall and didn't require tuning - be prepared just in case.

Re: Stalling?
 

It's a 98, We were told that 3200 was basically the limit to stay with stock tuning. We already have a Tranny cooler, Hadn't really heard of people breaking more things just adding a stall. Nor It being turned into a race car with this stall, I don't remember off the top of my head what brand stall but they said it kept stock feel and gas mileage, till you opened up the throttle.

Thanks

Funny how you want exact details of what we "think" will break yet you just now told us it was an Fbody for the first time. :D Anyway.

Possible failure list due to increased stress on drivetrain:
Rear end; Tranny mount; Motor mount; Universal joints; Torque arm; Control arms and bushings; Transmission (even if it has been rebuilt the service life will be decreased); The engine will need to be serviced more regularly with severe driving habits too.

So pretty much the whole car. However, I don't think the wipers or window motors should be affected. lol j/k

You missed my point before. It's not that installing a high stall will kill the car. Making a daily driver into a race car can cause a car to be less dependable. The LS1 Camaro/TransAm can be very dependable in stock trim while still giving exceptional performance and economy. That was my point. And seeing as your girlfriend seems to not have a lot of experience driving a car with a non-stock stall... and the parents are paying for the repair... and putting 2 and 2 together...

The last thing you want to do is decrease the reliability of someone's only means of transportation. Pissing off the financial support of said vehicle might not be a good idea either.

BTW - A bottle fed, high-stall LS1 could easily hit 12's and 11's in the 1/4. That sounds like a race car to me.

Do I know that any of these parts will fail? No. But you asked for opinion and got it. If you wanted to get a list of supporters to try and convince your girlfriend to hop up her car, that's what you should have asked for.

[Not trying to rant or be insulting in any way - Just sharing a little hard earned wisdom. You seemed a bit defensive.]

Re: Stalling?
 

If she never puts sticky tires on it none of the above is likely. All she will ever break due to a high stall is her tires loose every time that she punches it hard.
I have a ST3800 in a street car that is driven as a drag car. It has the stock 4l60e still in there and a 10 bolt rear end, full interior and almost full weight on slicks. Nothing has broken in over 300 passes since the install. But it's not street driven so no down shifts. It's my belief that the most damaging thing that you can do to a 4l60e is hammer it say in OD at 45 mph so that it drops to second. Again with a stall and street radials, bam, tires up in smoke.

But just as stated above any mods can shorten the life of some related components.

The only thing I would be worried about with on that list is the rear end and as it's been said it shouldn't break without sticky tires. But then again I've seen totally stock 98 A4's launch on street tires and break the rear end.
The tranny Is coming with a race warranty a year of racing and up to 700 Rwhp.

As for her, She just likes spending the money and buying various things to test them out. She doesn't have time to come on here and ask questions. She's either out to eat with me, Helping building my motors, Working on her car, and most importantly going to Med school.
She thinks it's fine to put a motor together and take it apart in a week to put in more goodies.

I guess it depends on where your from, and what your around that makes your views on what a race car is. We've driven in a few high 8 sec. cars that were street driveable and were daily driven. It's amazing how a Z06 in your book is a race car, a few people in our area put sticky tires on and can do 11's yes thats stock other then tires.

Oh and yes all of this is 1/4 mile times.
A person can be online smart as to going to peoples sites and reading what they broke, but I don't want to talk to a person like that. I know all of that, I want someone who is doing it right now. Like the other Person with the 3800 Stall. I have No idea of all the info based around them breaking something, some people say you can break an auto just from nitrous. Then you find out they spray wide open, from 2K from 1st through the shifts all the way through third. Now were talking the difference between proper care and abuse, But somepeople don't tell the whole story especially not on web sites.

Re: Stalling?
 

I guess I should have stated what Car I was talking about, I am sorry I am on a Camaro Board in an ls1 section and have to state what I have.

She drives a 98 Camaro z28 A4
I don't have to convince her to wanna race, She likes beating the guys. Her first Car was a Toyota Supra Turbo Manual.

Re: Stalling?
 

I take it all back then. Since she likes bating the guys, likes spending money and goes to med school (I assume you threw that in to imply that her parents are loaded), I say mod the shiznit out of it and enjoy. Life should be enjoyed to the fullest. And since nobody agrees that a dependable daily driver can be ruined very easily (not always though) I'll politely butt out, even though I have broken motor mounts, tranny mounts, transmissions, U joints and other stuff by beating on cars (one had a high stall too) in the past.

Good luck.

Re: Stalling?
 

Nope Didn't throw it in to say they're loaded, just to say I've got a smart, Pretty Fiancee that likes cars. With almost all of the things you've metioned, she's broken with a pretty much stock car. The Passenger axle half the teeth were I guess considered twisted, and shredding. And She doesn't just throw money around she saves, till it burns to hold onto the green and buys the first thing she gets her hands on.

I love to get into friendly chats, I Dislike some boards for the stupidity. Hope to talk again.
