This is cool. In for results.

what ecu are you running red/blue or green/blue?

cyipher

iTrader: (1)

any more info on this? will it work on the later blue/green ecus? I went looking over wiring pin outs and all i see is a torque limiting pin, but there is a traction control table and torque limiting table in my ecu.

here is how i wired it.

youll have to also disable whatever trans codes it throws, or else it will always limp mode the trans, and then you will be stuck in 2nd no matter what.

let me know if it works for you guys

Would this work with the harnessed spliced for manual operation (read thread about it on yellowbullet. Or only ran threw stock pcm

Possibly

if you put the transmission in 1st.... you enable solenoid A...
if you add in Solenoid B via a switch.....you are actually enabling 4th gear...not 3rd

so are you switching solenoids? or are you just adding the other solenoid?


oh...and the reason it "limps" into 2nd...is because it disables the voltage to both solenoids when there is a fault...which puts it in 2nd by the nature of how they work.

1st = Sol A
2nd = No Solenoids
3rd = Sol B
4th = Sol A+B

So is there a solenoid for rev?

soundengineer

iTrader: (16)

its a physical change for reverse, not a solenoid change
which is why you have to have a physical trans brake installed and you cant do it with a voltage change to a solenoid internal to the transmissions normal operation
its a physical valve that sends fluids to both the forward and reverse gears at the same time....locking them both on resisting each other....
when you let off the trans brake, it closes the valve passage and disengages the reverse portion


reverse uses Solenoid A
Neutral uses Solenoid A+B
Park uses Solenoid A

When in manual 3rd it can't hit 4th
So I choose 3rd and hit the switch

So this works with the gear shifter in drive? I let the computer shift for me.

I did this a couple days ago. No codes needed to be disabled, I already have a relay on the Solenoid B output since I am using at 4L60e tune. I simply grounded the solenoid after the relay and all is well.

denmah

iTrader: (2)

ah yep!
slow67 told me that if you do the relay swap for the 60e it will work simply like that

slow67

iTrader: (2)

Yeah you want to race in 3rd, not 4th (uses overrun clutches).
And yes, your commanding 4th, but it cannot get 4th gear when the shifter is in 3rd.

As far as reverse, it will go into reverse regardless what the solenoids are doing.

So is this still working? No scattered trans? I'm aching to do this, especially since I already have my 80e working on a 60e tune.

I also had the same problem Denmah was having, could only get 2000-2100 before pushing through brakes or spinning back tires and could on get 1.95 - 2.0 60ft. Put shifter in 2nd and could get 3500 and leave with some boost and got it down to 1.65 60ft and think I could have gotten it better but ran out of time. Only thing is your leaving in 2nd gear, how bad is it on the trans to leave in 2nd like that?

denmah

still works fine, going to race the car friday at island dragway and test this out first hit

i would like a schematic how this works (how you did it). i have a 4l80e with a 4l60e operating system also.

cory32690

could you wire it the way you have it and instead of using just a switch to go from 3rd to first could u just make a arming switch for it then put like a wot switch under the brake pedal to activate that way when ur staging u don't have to time letting off a button or flipping a switch just let off brake and boom drops back to 1st

got-a-ls1

iTrader: (12)

how fast does this work denmah? is it basically back in first when you let off the button? im curious to try this next year but am worried to blow the trans lol
