im not too mechanically minded when it comes to clunks and noises so I need your help. I've noticed every now and then when I change from 1st to 2nd I get a bit of a clunk noise (and feel) it was nothing really but just then I put the car in reverse, moved back a little then CLUNK and I stopped. put the clutch in, changed to neutral then reverse again, and reversed off fine. it almost feels like somethings shifting, like if I roll slowly in 1st it could go CLUNK and jump forward. I know my explanation is pretty vague and contains the word CLUNK alot, haha any insight would be appreciated!
