My 11 second queen has to come apart

[Foose04]

Well, another nice long trip to Carolina Dragway to run 11s. Thanks to Gerald, the Trans-Brake is installed, works great. However, new problems include the rims are spinning inside the tires even on a my test launch at 3100 that cut a weak 1.79.

Next run turned it up to 3700 and around 17psi on boost. Something was off on the two step though as it left at 4200@17psi, shocked the rear tires hard and unloaded on the rebound. Also turned the rims about 3inches. Cut a 1.64, then all the problems. The transmission is for sure slipping, I was at 89mph and 3rd gear @6300RPMS. Even had to shift to 4th to get thru the 1/4 off the limiter. Fu**.

So, the only thing thats truly "built" on my whole setup is f'in up, should have tried a stock 4l80E.

However, made it home and beat up on a Heads/Cam GTO. Guess I should be thankful for something.

So I still have a shot at getting a 10 first? Sorry about your troubles Rob.

what color was the h/c gto? srry to hear about your trouble.

[Foose04]

Someone needs to get it done man, best of luck to you. You got the suspension/drivetrain working, that seems to be 80% of the battle on these heavy rigs. I've had the HP since day one, just not everything to make it work for me.

JMD it was red, said he was from Georgia. He's in the video after the first run.

manuals FTW. lol slips?, change the clutch. answer your phone bitch!

I never have had much faith in complete transmissions that are sold via long distance. When there is a problem, diagnostics are done long distance as well. Sometimes the whole transmission has to get truck freighted back to its maker for a solution.

I feel for you, Rob. Those people sent you the wrongly configured 4L80E transmission to you to start with. Then they want to try to modify it into the configuration that you originally wanted via long distance wrenching by me. From what I gathered on the phone with these guys this week, the transbrake valve body they sent isn't quite like a ground up built configuration that you originally wanted. They told me that they do modifications to the case passages when a transbrake configured unit is built in house. Obviously, your current case isn't modified in their usual manner, so they are attempting to do it all from the valve body side. Apparently, it still isn't right.

As far as transbrakes go on 4 speed autos, generally they don't release as fast as what folks are accustomed to in an older, simpler 2 or 3 speed auto. There are lots more fluid passages with longer runs and it takes more time for reverse oil to dump when the transbrake is released. You can't fight physics.

A 4L80E physically is one stout piece. But just like any other auto, valve body issues can wipe out a well built rotating assembly.

I don't think Rob likes vehicles with three pedals anymore...

What company built the trans?

[LXtasy]

CKPERFORMANCE built the transmission

[Foose04]

Game time. After some more research and talking with Gerald about everything, I decided to start fresh with a whole new build/trans. I decided on Jakesperformance, as his bread and butter is 4l80E's and theres some fast rides running his 80e.

I'll find out soon, got a couple days off to start the install, drink beer, then finish install. This is Jakes 2.5 Build, with billet forward hub and billet input shaft and with transbrake. He said it's a beast and one bad bitch, I hope so.

That said, 10's this weekend??!! Damn I hope this SOB can get the job done already.












Rain tires looking strong....

Is that jack stand really on the shock or does it just look like that?

[Foose04]

Sure do, it's the only point I have to get the truck high enough to clear the bell housing under the side frame rails.

Very nice.

[minytrker]

So you still didnt learn a lesson about mail order transmissions? I would have went with Gerald hands down. Hope this one works out better and you can get your 10sec pass.

[bwelch]

I have a tranny jack if you want to borrow it. Its alot better than a floor jack.

Pm me if you need it.

[Carlrx7]

he has a bottle of jack he usually lets me drink, then it just falls on me. lol

[bwelch]

This is it.

I got a buddy with a silver truck that has one of those 10 second slips if you need to borrow it.
