Vehicle goes into "limp mode" daily. Seems mostly to occur once coasting or slowing on a off ramp from highway speeds. Can put car in neutral then turn off & restart which seems to reset "limp mode" until speed decreases to roughly 20 - 30 mph. There seems to be multiple other drivers with this car that have the same issue, yet no response from Chrysler.
Was traveling in third gear when the transmission downshifted to second gear independently. Transmission locks in 2nd gear (limp mode) when slowing or stopping vehicle. Once you turn the car off and back on again, you can drive with normal gears. However, once you hit 50-60 mph, the transmission automatically goes into limp mode and stays locked in second gear. Check engine light came on and it now reads the codes p1776.
Tl- the contact owns a 2004 Chrysler 300m. While driving approximately 35 mph, the rpm reading suddenly increased independently. The contact stopped the vehicle on the shoulder and turned the engine off. After restarting the vehicle, the failure ceased. The failure recurred intermittently. The vehicle was taken to an independent mechanic for diagnostic testing. The mechanic was unable to diagnose the failure. The vehicle was not repaired. The approximate failure mileage was 140,000.
