    Question 4L60E Transmission Problem

    Hello people. I have a problem with my 4L60E transmission after install Dominator ECU.
    I haven't a 2-3 upshift. After a ECU send signal to transmission (Shift to 3 at statistic) it turn to neutral but not upshift next to 3.
    Anybody have same problem? I have stock 4L60E transmission.

    Did this transmission function properly before the Dominator EFI installation?
    You may want to position the drive axle up on jack stands, and probe the 'Shift Solenoid B: 2-3' white/black wire for activation (at the transmission end of the wire harness). I don't know if it's a 5V, 12V or ground activation; but you'll figure it out (compare it against 'Shift Solenoid A: 1-2'). If you do get the Shift Solenoid signal, then it's not an ECU or harness problem.

    Hello, I need some help again. Now I have a 4L60E 5 solenoid transmission with some performance parts:
    http://www.ebay.com/itm/700R4-4L60E-...-/200660185262
    http://www.ebay.com/itm/ACDelco-4L60...18b533&vxp=mtr

    Now I have no reaction of my car when I shift to Drive. Only manual shifts, like no communication with ECU.
    I checked pins with voltage tester and they look fine. I try to use 4L60E and 4L80E Dominator transmission configs.
    On 60 config my transmission have only 1-2 shifts, no 3-4. On 80 config I have 1-2-3 shifts and transmission goes to neutral, not to 4.
    At each configs I have no 1st gear when I shift from neutral to drive. No I have no variants how to fix this. Please any help.

    I would first perform a continuity test (Ohm meter) on every wire in the Holley 558-405 4L60/80E transmission harness.

    I know this is old thread, but what % did you set the line pressure at?

    Without knowing the PSI of the transmission, it's hard to say. I put a pressure transducer on my transmission. I use 40% at idle and 20% at WOT. That gives me around 100 PSI at idle and 225 at WOT.

    Is this for your 2-3 shift? I’m trying to install a pressure transducer this weekend.

    There's a chart in the EFI software that allows you to increase Duty Cycle based off Gear & TPS.
