I have been hearing about code problems with a 2001 car and a toqe convertor. Is this true?And what are they?

 

I had a problem or two...

 

TR:

I thought that I had heard that you have experienced some shudder with your Vig too. Any truth to that?

BTW, i'm not knocking the Vig; just surprised since the clutch material is different.

 

No, no shudder problems with the Vig. I'd say there is a little bit of vibration (VERY small amount) over the stock converter, but it's barely noticeable.

 

'99,

Now that I think about it, maybe you were thinking about the excessive slipping and shuddering I DID have immediately after I picked up my car from having the Vig installed???

If so, that was caused by the trans shop that did the install underfilled the trans by about 1.5 quarts and I didn't think to check it before I left (shame on me).

When I got home, I filled the trans properly and all was well <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> .

 

Glad to hear it worked out. vibration increase is no surprise; anytime you change to a smaller and lighter converter you loose some of the dampening effect of the larger mass.

Yank has changed the clutch to deal with the '01 issue.

 

cmon guys, like u never had something like TC went sleep, u reving but not going faster...

vig3200, 2k1 trans am

 

so its only me and a few local guys ?!

 

TomQ, sounds like bigger problems.. clutch slippage..

 

I don't know if it is the converter or not but something is up. The best time that I can get out of my setup is a 12.65 @ 107. This is with a 1.85' on ET Streets. This is the best 60' I've seemed to get b/c it won't do better. I don't even know what is causing the mph loss. I've put posts up on other boards and no one seems to know. But I was talking to a friend at the local shop and he was saying about torque management. I'll get the car tuned and if that doesn't work I'm pulling the verter out. Anyone having trouble with Yank lately?

I imagine that converter and a set of 3.73's will really get me rolling.

The Problem: my car is a daily driver (65 miles in traffic <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> ) and I'd have to drive a set up like that before I do it so I know whatI'm getting into. Of course no one in my area has anything even close to that converter...

 

I found the YTP 4000 & 3.73s is looser than a ST3500 & 3.23s. Using edit to raise part throttle shift points (e.g., hold second gear longer) and a low lock-up speed in 3rd helps tighten it up.

It is an awesome combo, especially on the highway. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Many of us 01 and 02 owners are getting this code with 9" converters. This causes the car to stick in 3rd gear and the TC to freewheel. This code doesn't exist on 2000 and earlier f-body's and won't be correctable until the next revision of LS1 Edit.

I went to a 2000 pcm in order to get rid of this issue.

 

Well,
i don't friggin know what's going, but i'm getting new 2000 PCM, programmed for my car,
2000 PCMs do not know about bad codes, misfires and other disaster.
injectors, etc was set for 2k1 car.

A friend of mine running this comb, he says Car flys, no codes, no ses lights, super duper, we'll see, i'm gonna post tomorrow after i'll install the PCM

Thanks

So Yank changed the clutch (design? material?) in the ST3500 for '01 cars? Has anyone run the updated converter in an '01 yet?

I might, maybe, possibly think about another ST3500 (I really do like that higher STR and top-end efficiency of the ST), but not until I hear one success story after another from people that have the updated ST3500 in a daily driven 2001 or 2002 car.

TomQ, is your car throwing codes now? What converter do you have installed??

 

P0300 Code after mine was installed.

 

I believe that he went with a slightly larger surface area and not quite as agressive a material, but I have not seen a sample of the new clutch. The new clutch material has been shipping for about a month or two, but I'm not certain as he had some supply issues getting it in quantity.

If you switch, I'd move up to a YTP 4000 series. Loose - yes, but top end is awesome <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

The odd part is that it always seem to happen right as I pull to the line at the track.

Yeah, the '01 PCM does seem to be a bit sensitive. We'll see what I can do if I ever manage to get a copy of Edit...

 

2000 PCM installed, car runs awesome!

need more test driving <img border="0" alt="[guns]" title="" src="graemlins/gr_guns.gif" />
and then on the track <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
