My car shifts or knocks hard when driving normal on the streets and highway. Yesterday, while driving at 55 mph there is a howling, pitching sound/noise.
I am having problems with the RPM. on 1999 Plymouth Breeze
3 speed or 4 speed transmission? Big difference in operation. In either case, check your transmission fluid level. If ok, My suggestion is to take the vehicle to a reputable repair shop of dealership in your are for diagnosis. Here is a link to your local repair facilities. http://repairpal.com/directory?address=89128&car_brand_names=Plymouth
