04 Ranger 4.0 v6 gear not catching...?
uh dont know much bout cars so bear with me. ok as im driving my truck and cruise around 40 mph the truck usually feels like its slightly jerking. i've asked people and they say it sounds like my gear is slipping. i took it to the dealership and they said its probably the spark plugs and they changed them and it didnt fix it. its not a real bad jerking feeling but it doesnt feel right. also, as i accelerate, i hear a slight high pitch ringing noise. someone told me that sounds like gear whining. i dont know what that is and how i would go about fixing it. i dont want to take it somewhere and they tell me is something that doesnt need to be replaced or repaired. can anyone tell me what the problems are from and what i need fixed?
