    4l60e with vacuum mod

    First off I am very need to hp tuners, I plan on learning, I just got my first hp tuner.

    Now the first. Thing I'm trying. Do is tune my 06 gto, it has a fully built 4l60e from rossler transmissions with a 3200 stall tc, also it have the vacuum mod for line pressure, and a trans brake. Ever since i installed this transmission is has not worked right, I pulled the transmission and brought it to a builder and he told me there is nothing wrong with it and I just need to tune the car for it to work right.

    Next I have long tubes and catless mids, the car throws a code a goes into limp mode since the new exhaust, how do I tune it to fix this?

    Thank you

    You need to post your tune and log files for help.
    What codes are in it?
    That kit eliminates the EPC (ECM controlled line pressure),that may require extensive changes to the trans tune?
    What is controlling the trans? A separate module or the stock ECM?
    Is this full manual control,with a brake?
    Ask your trans guy who tunes his trans with this change.
    The better details you provide,the quicker some one will help.

    How do I post my tune and log files? It is on a completly stock tune right now, on the factory gm gto ecm. Not full manual with the trans brake. I will get the codes off of it after work. Thanks!

    Ok, so you have the trans go vac modulator, only thing to do would be to put the resistor in line at the epc plug to prevent an EPC code (or turn off the code report). As long as it's not a manual valve body and shift solenoids A and B are plugged in, you should be able to command shifts based on VSS, RPM, and TPS.

    Are you getting voltage to the trans? What specifically are your symptoms? Exactly what will it do or not do? The more info you provide there the more I can help. To post a tune or log you can hit "go advanced" and upload the file and then attach it to your reply.

    the car drives fine, you just have to let off for it to shift, and the converter locks up way to low. i was told to alter something with the the torque management? im not getting a code for the transmission, im only getting a code since i deleted the cats, it is a system to lean code.

    System too lean, is not a cat code. You are not getting enough fuel, if this is the case you need to get it fixed

    Yes, hptuners gives you the ability to see, within the ecms capablities, what is happening. The rest is mechanical checks, and "your" abilities.

    i cannot get the car to thow the lean code anymore since i delete the diablo sport tune off of it, and put the stock tune back on it, however i am now getting the following codes ( p0128, p0036, p0054, p0056, p0060) also the toque converter will randomly unlock on the highway, and it got a rough idle, no misfires detected.
