Grinding between 1st and 2nd gear

Sounds to me like slave cylinder is out.

normal,hyundai plastics have always been rubbish

gear change linkage worn to excess ,

The 2nd gear in the transission is not working, the transmission need to be repaired, if in the early stage, once it is broken down the mechanic will determine if the transmission need totally rebuilt

YOU NEED TO TAKE YOUR TRANS OUT AND HAVE IT REBUILT, THE SYNCHROS ARE WORN OUT!!
THAT IS WHY YOU HAVE TROUBLE SHIFTING GEARS!!

Either your clutch is getting bad, or you're shifting down too soon, and up too late. Try double clutching. Push in your clutch and push it into neutral. Release the clutch, fan the gas pedal, push the clutch again and shift into 1st. All this does is sychronize the speed of the transmission with the speed of the engine. There were, in the 60's, a lot of cars with the old "three on the tree" that you had to do this every time, and you get pretty good at it after a while.

Hi and welcome to FixYa,

In a manual 2001 Hyundai Accent, the clutch cable could be adjusted. The adjustment point is on the cable 'pad' where it enters the firewall in the engine compartment.

To adjust, the slack or free play must be decreased. This is done by turning the adjusting nut clockwise. Check back by pressing on the clutch pedal to your preference.

Good luck and thank you for using FixYa.

first of all you shouldn't be reving that high to change gears. that's too high. secondly if it's grinding only during the change from 1st to 2nd gear you may have a problem with the gears not being aligned anymore...ie synchronizers worn out, bearings worn out, etc. take to reputable transmission shop to get it diagnosed and repaired. it sounds like the synchronizers are a problem there. and you may have metal in your fluid now that it's been grinding which will affect the rest of the transmission. if you are speed shifting as in racing, you are not doing your transmission any good. you probably don't have a transmission built to do that if it's the original factory tranny... meaning you did a major NO NO to your tranny and are tearing it up speed shifting when it isn't built for racing.

there are a couple of diodes under the hood that need changing at about 12 dollars each.should solve your problem
