6R80 transbrake you say?

I figured that's why you went thru all that extra trouble to raise the line pressure. You couldn't get the car to even hold back an N/A car could ya?

All bullshit aside I you don't ruin any engines from raising the line pressure in the tranny

Sweet

Lund had the pressure raised in my old 2011 and you could count the change in the console when it shifted It hit gears like my Terminator used to with a PA Pro-Mod C4

Nice!, but you're really mad at "magic boxes" aint you?

Car sounded good to me.

It actually sounds like it's on a brake at wot.

Unless I'm missing something?

I just watched the video of Chris' green car again, and it sounds to me like its still foot braking, trying to get the right rpm for launch? Right before it launches, I hear the rpms try to push a little more.

And that's not a jab Dustin, just an observation. Normally with a brake, you go wot with the pedal, and it's done. The green car just doesn't sound like that, you can hear the rpms creeping the whole time.

I like the fact that everyone is getting after it with the brake.

Your videos always crack me up Kris. Keep up the good work

 

[CPRsm]

Of course. Line pressure raises shift firmness and holding pressure of bands and clutch packs. Changing the tune in these cars is like changing springs in valvebodies for shift kits and transbrakes in older trans like your C4. But you can have line pressure too high. Google thrust bearing problems on mod motors w aftermarket trannies. Especially glides and 400's. why do you think MMR makes a rollerized thrust bearing for mods? Otherwise have at it. My panda fu is weak lol

Iirc Hanlon had a writeup of this very problem years ago

Well sure. It was bound to happen whenpeople know it can be done, and they're not completely wasting their time. It was really just a matter of time. I had been talking to a few places about selling them because I just don't want to.

If you listen to Chris's car you can hear he doesn't hit his two step. It's because it's still wired to his brake pedal. So you hear him trying to control the rpm and boost w the gas pedal. Which is damn near impossible on a turbo that spools that quickly. Obce it's into the load the turbo wants to GO. So if he was on the foot brake you would have heard his two step. I the latest vid he was going to trigger the brake lights to activate the two step but he forgot lol. Actually come to think about it I don't think you hear a two step on any of his vids

I go WOT in my car and it will flash on the brake and then as it spools, making more power, rpms creep up until it hits my 2step. That is just how things work in a turbo car that continually makes more power with load and time. Some people also stall against the foot brake to build a little pressure before lighting the 2nd bulb and grabbing the brake to make things quicker/easier.

Curious to see how the 6r80 holds up to brake abuse at big power levels

I agree with this statement. I have owned many turbo cars in the past with th400 transbrakes and I let the car sit at wot let the rpms creep as it pushes through the converter then it sits at the desired rpm/Two step and continue to build boost from there with some sort of antilag. For an n/a car I would agree with just going WOT straight to two step. Two different animals.

 

[REDS197]

Do you have a turbo kit too?

 

[Mystickeith50]

The brake thing is cool and I've been reading every post in all these 6r80 trans brake threads and I just don't understand the hate Kris. You got a problem with dustin...fine, but the fact of the matter is he figured out a brake... so did u. You are obviously smart...u ruin it with your constant hate of everything that's not Lund tuned or faster than ur car. If dustin wanted to sell something he came up with, why not... its the same as tuners selling there tunes. If he wants to sell it only to his customers why not... afaik Lund won't even tune a turbo coyote unless its his kit. If you want to give away ur time and effort for free have at it.... but just know Dustin is not the only person on here trying to sell something. is there something I'm missing? Or is it really just u hating on him because he supposedly can't produce a car as fast as your n/a car? I'm curious....

 

[kdanner]

Google thrust bearing problems on mod motors

Ah, a classic strategy. If nothing else, spread the FUD in order to better yourself.


FUD=fear, uncertainty, and doubt in case anyone doesn't know.

 

[SSPSTANGBANGER]

you can have line pressure too high. Google thrust bearing problems on mod motors w aftermarket trannies. Especially glides and 400's. why do you think MMR makes a rollerized thrust bearing for mods?

Yes line pressure can be too high but that has nothing to do with crank thrust bearing.
Now a ballooned converter or improper bellhousing indexing or bellhousing depth can cause thrust damage just like a improperly installed clutch or damaged input splines and clutch disc binding on a manual trans.

The aftermarket trans crank failures are 99% due to improper bell housing indexing or over powering a tq converter and it ballooning against the rear of the crank

With a cast-on-trans bellhousing on the 6r80 and a billet converter like circle d there should be no damage to crank thrust by the trans regardless of line pressure.

Haters gonna hate! Lol

I seriously don't understand it either.

Yes line pressure can cause issues with these motors and thrust bearings. I had it happen to my car. I have a thread about it that is in the 2005 tech. My trans cooler lines were restricted and caused higher pressure and it did major damage to my crank, block and chewed up the thrust bearings.

Your lack of understanding on the basics doesn't make it FUD. How will it better myself to knock your design if I still won't sell mine?

Sorry man, they can cause it 100%. Indexing a bellhousing is a shift in the bell left or right laterally on the engine. Nothing to do with depth. Not having proper converter clearance for expansion or ballooning can certainly cause it.
The transmission naturally tries to push out the converter because of the fluid and pressure in it coming from the tranny. As that pressure goes up, so does the push on the converter. T400's are known as crank killers for this reason.

Tuners do the same thing all the time, and maybe people don't correlate the two. If you want lunds lope idle, will he give it to you or sell you the value file? Nope. You do have to buy his tune to get his idle lope. Some how everyone is OK with that. But not OK and even upset I won't sell my "lope tune" separately. Makes a lot of sense huh?

Line pressure does not equal converter pressure. More FUD.
