    ok i was thinking that someone might of had the same problem my c4 has trouble shifting when i get on the gas, and some times dosent go into second at all. but this mostly happens when the car is acellerated quick, when you slowly pick up speed it generally will shift though the gears ok.

    How fast do you get going before you decide it won't shift?
    When accelerating hard (WOT) the C4 will shift 1-2 at around 40 MPH and the 2-3 shift won't happen until above 70 mph.

    it seems to get stuck in first and dosent shift even at 3Xrpm then i naturally slow down because of it.

    Ok, When you are accelerating hard it should not shift until 4800 to 5200 rpm.
    If it shifts normally when you accelerate at light throttle then you probably don't have a problem. Does it shift gears when you let off the throttle?

    Stuck governor, Stuck 1-2 shift valve, or warped valve body.
