1997 Honda Accord gears

1997 Honda Accord 4 cyl Front Wheel Drive Manual

I have a 1997 Honda Accord 5 speed, I recently hit a curb which lead me to have just about everything replaced from the axcel, spention bar, arm, spindel, bearings, struts. Just when you think the worst is over I am facing another problem. My car takes forever to go into gear, I did not have a problem with the clutch when I hit my car took off with full power as soon as you placed your foot on the gas pedal. I am being told that I need a clutch although I keep telling everyone that when the man worked on my car I seen him empty out the gear oil from the bottom of my car, I know he never replaced it because I caught him telling someone he did not know exactly how to put it back in. OH MY GOD I told him leave it alone I will take it to someone who knows. Well my problem is everyone I take it to seems to have difficulty hearing me say I saw the man take out the fluid all they are interested in telling me is that I need a clutch. Ok if I do need one fine but why wont they replace the gear oil as I requested? Please tell me how to replace it myself and then I will look into finding an honest person to work on my car I have put so much money these past few months
