4L60E Transbrake

[Gen 3]

Hi all, Als race glides are install a transbrake in my 4L60E transmisson. Hopfully I,ll be out next Wednesday,if not anzac day at WSID. My VX has run 11.54 @ 118.9 mph. So maybe my ET mite be closer to my MPH, low 11's ? My 3500 stally should now be launching at an extra 1000 rpm so i've be told. :driving:

[APCLB]

Had to be done,I'm interested in seeing this.

:worthless:

[T_Kiwi]

i would be interested in how much this costs mate?

[Gen 3]

You would have to talk to Al on (02) 97925999. Far as i'm aware besides his own car mine is the first car he is installing it in. I'm still waiting for mine to be finished :cussing: His waiting on a input sharft from the states, there are none in oz at the moment. Hopfully i'll get it back within the next week or two so i can give it a good test before the next track championship at WSID. At the moment i'm coming second in super street and i want to make shore nothing breaks. l'll keep you all posted if you like on the testing & the differance it makes and which Wednesday night i'll be at WSID

Niiice launch, seems to have an after market trans pan with fins :)

Thats Als car. His 60 foot is 1.6, mine is already doing that without a transbrake. :yahoo:

Just a suggestion why not just go a bigger converter. 1.6 60fters isnt real fast these days. Iam doing 1.54 60ft launches on drag radials with my car just with a bigger stally than yours. Markone2 is doing 1.48 launches just off the stally and Leatherman doing 1.50 60fts just off the stall aswell. No transbrakes needed here.

I have to agree with you Jim. For a bolt on / Cam / H&C id just put a bigger stall in. But for a Turbo car you really cant go past one :deal: With any luck I should have one before I hit the track again :idea:

Yep i agree there Gareth i think its well worth it on a turbo car.

[Gen 3]

I was going to go a bigger stally, but i drive my car a fair bit. Using a transbrake i can use the 3500 for street and cruising, which is more then enough with street tyres. But when i'm at the track i should have an extra 1000-1500 for a harder launch. I think for me this was a better way to go.:thumbsup:

[VILLAIN]

A trans brake is a great idea, a 6000 rpm stallie is a bit to racy for road use and your fuel consumption would be horrendous.

You need to have driven a 6000 stall on the street to realise they are no different than driving a 3500 stallie upwards. The only thing is it doesnt have a lockup but still cruises at 2400rpm at 100klm no probs.Mine actually drives better than my old 4000 stall did. As for fuel consumption its not that bad. Currently averaging 19 to 20L per 100klms. Highway drops to 14L per 100klms. Iam also running a cam in the high 240s so the fuel consumption is pretty good considering.

[Oztrack Tuning]

How can it add an extra 1000rpm - interested to know. Its not just because it can be loaded up harder is it??

Im curious if this mod can truly make for faster launches?

:rofl:

But with a trans brake AND a 6K stallie - you would/should be able to stall the car up to 6K on the line and then BANG like dropping a clutch in a manual - should be good for a lot better than the low 1.5's - high 1.4's that people get at best on here even with 10+11 second cars.



Who makes them in Aus to suit the 60's and 65's?

Bob Grant in Brisbane has done them, I think he might use US components, like Rossler, Or something through Gil younger.
he may do the valve body mod himself.

I will know tomorrow.

?

No need for trans-brake....watch this space....1.3's coming very soon :driving: ....on DR's

[STATIE]

What - are you going to put an 8 grand stallie in it now?:lol:

[RedVYIISS]

Well Gen 3.... how'd it go? (I'm assuming you have some results by now?)

[bermudablue]

I'm not 100% on this but i think this car is almost stock modwise.
So he's going ok

[markone2]

Simple application of mathematics combined with larger footprint..answer is only 2 days away ;)

[dogsballs]

i don't think bigger tyre is necessarily better, look at tonner, he went better with the 26x8" slick compared to the 26x10", (although that could've been weight of rim)

[Gen 3]

No results yet, waiting on customs to release input shaft. Should have car back this week. As soon as the keys are in my hand i will be off to WSID a.s.a.p. I will keep you posted. Till then i've got nothing, not even a car:banghead:

:idea: think up instead of across

[STATIE]

Your always so damn crtptic Mark - spit it out man.:jester:

[UTE FORCE]

I cant wait to see one of these transbrakes on a 4L60/65..should be a good tool for the boys already running an auto to shave a little off their time...cant see it helping the boosted guys much...unless frequent transmission builds are available...hope im wrong

[Tonner]

:idea: think up instead of across

the 28" ripple walls?

I wouldn't dare, could be a waste of money in my case anyway, we are going to try different type of clutches again and trans fluid and mess with the pressure to 3rd piston, if it doesnt work this time, its out with the 65 and do something else.

[markone2]

Your always so damn crtptic Mark - spit it out man.:jester:

Certainly..:thumbsup: *Mathematics*...

[Gen 3]

For those who are interested in the 4L60E transbrake. Als decided to give me an extra 500 in my stallie taking it up to 4000. So he tells me with the transbrake on i should be able to stall up to at least 5000 with foot flat to the floor. Can't wait to try it out, just hope that the Wednesday night track prep at WSID can handle it ! WHAT TRACK PREP ! So next Wednesday nights the go. The plan is to at least have one run without using the transbrake so we know what differance it makes. Hopfully get some traction to give us something to work with. If any body has any questions on exactly how it works Als more than happy to answer them on (02) 9792 5999 or he will be at the track with me on Wednesday night. I'm sure i've spoken with some of you before. I drive a white vx ss with the rear spoiler taken off & with a Sams performance sticker on the rear window, if not come & say g'day its good to talk to other people about what mods they have done or what they want to do. hopfully i'll see you there.

[VILLAIN]

I for one am looking forward to the results, hopefully all goes well.

[Gen 3]

Finally got out to WSID last night ,but not good news. My stallie didn't make it back from Melbourne in time, so we put another 4000 stallie in that Al had sitting around his work shop. Launch didn't feel to bad 1.5 s/f but got worse from there. Felt like something was slipping lots revs but not alot of pushing, run 11.73 @ 113 MPH, 2nd run 11.80 @ 113 MPH. Third run I didn't use the transbrake ran 11.65 @ 115 MPH still felt like something was slipping, but scored the best R/T for the night. Fouth run used transbrake 11.74 @ 113 MPH. My conclusion is cheap s*#t stallie was slipping down the hole track and alot worse using the transbrake. Back to Als tomorrow to get my stallie put back in and hopfully next Wednesday night I should run low 11's.:cussing:

[Gen 3]

Al put my rebuilt stallie in yesterday. That :cussing: stallie that was put in we're 99% sure that was the problem. Just driving it on the road felt 100% better. So next Wednesday night I'm 99% sure that i'll get a positive result, 1% :cussing: knows anything could happen.

[Oztrack Tuning]

Good luck Rod - keep us posted. It would be a nice to see a NSW sub1.5s from a car like yours.

[Gen 3]

Thanks Steve, just got to practice using it. My r/t was really bad, would have to be alot better for me to use it when I'm bracket racing. Good luck with your box.

[Gen 3]

I'll keep this short & sweet, or not so sweet. Still having problems, for some reason the transbrake is robbing 2 to 3 mph which is slowing the car down by about at least 2 tenths. Al has some ideas how to fix this, i'll keep you all posted hopfully in the near future.

[CRAIG LS2 GD]

Any news on the trans brake have a 4l60 in mine with a 4000 stall doing 11.22 122mph interested too see if the trans break is worth the dollars,, cheers craig.

Mate,

I saw you out there on Wednesday night only saw I time from you in the 11.5's what was your best for the night?

Any update on sixty ft times yet :confused:...I've been watching closely in genuine interest as to the merits of fitting a transbrake to the A4....while I firmly believe in the merits of Drag radials ,combined with a carefull selection of high stall and diff gears for fast launches, I'm always looking for ways to improve my current 1.48 sixty footers

[XR4TED]

Sorry to hijack the thread but hoping someone can help. I have a 3200 stall in my car but can only seem to stall it to 2000rpm anything higher than that the wheels start to spin. Why is that and can the rpm limits be changed? and are these designated limits set on convertors? i.e a 4000 stall should be able to rev to approx 2800 before spinning? I tried the search button have not got the answer yet. From my limited knowledge it would seem that from this thread a transbrake does allow for this.

Cheers

[Gen 3]

Transbrake still isn't improving my 60ft, where at the start it was losing now it is the same with or without using it. Don't no where we are going from here maybe the IRS has something to do with it. My take on it is that by squatting the rear down with the foot brake & hand brake is getting the power straight to the wheels. Using the transbake i can't do that & it is absorbing the power I'm not sure. There is still a fair bit of testing to do, with a turbo it would let boast up it would work. On a n/a car with the right suspension set up just maybe.
Didn't use transbrake on Wednesday night. Spun wheels a little off the line run 11.46 with a 1.57 60ft. best 60ft was 1.55 but car spun when it changed into second & start going sideways. Had eight runs with all of them braking traction at some point. Some body going to be seriously hurt one night if they don't start prepping the track! Mite even see a 11.3 if condition are right.

That is normal your convertor will flair to 3200. Just make sure you get your shift pressures checked, sometime your pressures drop with a bigger convertor.

[dogsballs]

anyone have any recent luck with these??
