    1996 AMG C36 - 2nd gear not changing to 3rd when WOT activated.



    Hello all

    When pressing hard on the accelerator the car sticks in 2nd gear at approx 5700 RPM, before the redline, and fails to change to 3rd. Its like there is a rev limiter that kicks in. This only seems to happen when the WOT button under the accelerator pedal is activated, otherwise gear changing is smooth.

    The scan tool, revealed the following codes stored in the ISC/CC (Throttle) computer
    -144 Speed sensor signal - fixed by replacing the ABS computer by made no difference to the running
    -145 ETS slip threshold exceeded. This issue returns after attempting to rev out the engine in 2nd.


    Appreciate if anyone could shed some light on this issue.

    Cheers
