    its a 3-4 shift solenoid circuit failure.

    you need a scan tool, volt meter and a shop that can trace down the issue. these diags are not for home repairs as most people dont have scan tools at home.
    a trans shop can diag it for you and give you a bid. the 3-4 solenoid may be the failure but you must verify the wiring harness too.
