It could be the Powertrain control module (PCM) if you have an automatic transmission or the synchro if it's a manual one, in that case you would probably hear a grinding noise when shifting. As for the reset button, I did not hear of a such thing but you could try reading the code using a code scanner (I think you'll need the OBD2 connector one) and reset it. Check the sensor connectors on the trans for any looseness. Make sure you have enough oil in there as well, automatic trans work with hydraulic pressure....not enough hydraulic pressure mean no gear shifting. Hope I helped!

Best regards, Sam

SOURCE: Transmission will not shift from

trans problem, internal. you would need to remove the trans pan and look inside of it to see if there is any debriss in it (chunks of metal etc) if you find any metal, you will need another trans and all tranny lines washed out and radiator cooler washed out also. good luck.

SOURCE: gear shifting on 2002 chrysler 300 m

transaxle reset mode page 148 of the owner manual. when the transaxle sensor detects an abnormal condition that can cause damage, it drops the transmission into second gear to protect the transaxle from damage. pull over to the side of the road, shut off the car and restart it. it may go away for a little while and let you drive normally. mine kept getting worse. I took it to the dealer and they had to replace a part that works with the transaxle (not the transaxle or transmission itself). it cost about $900 and took them 3 attempts as the first two replacement parts were bad out of the box.

Engine revs.at 4500 rpm. at 100 kph. what could be the problem, thank you for help.


If the model is automatic then there is fault in the gear box as the gear is not shifting to the RPM.
Secondly if this the manual version the clutch can be faulty as it is slipping and not fully engaging to the engine.
