When i put my car in reverse it moves but shakes alot. It also does this in first but once i have enough speed it goes away..i can't find out what it is...also when i drive a lil fast i smell something burning....I thought it was the tranny fluid since i just bought the car. Change that and still the same problem....found out the inner cv boot is have gone . Could that be something causing it?

 

dude if ur cv joints bad that would be ur problem fix that $hit
