alright everytime i take off hard in 1st gear with the rpms gaining i get a knocking noise that increases with the speed...when im in low rpms it goes away but comes back in all the other gears in high rpms i kno its not the motor because i revved it in neutral and there was no noise and everytime i shift i hear a clunk...apreciate the help thanks

 

when did this start to happen

 

my first thought would be, it's your tranny.

 

does it go in every gear smooth..and check your axles..might be busted
