Hi i have this issue with my s14 tranny (ka). It grinds from first to second and sometimes the reverse pops out. At times even it grinds when i leave it at first gear. I usually just double clutch my way through so it wont grind. Now i have this issue that sometimes when i make a turn on a stop. That car starts to jerk and i try to press the gas it just keep jerking and stalls after in the middle of the street. Yesterday it happened on a big street and scared the crap out of me. I had to turn off and turn on my car to make it work again. I am not sure if its the clutch or tranny that i need to replace so please help me outs guys thanks.

Your transmission is in trouble, your clutch isn't responsible for the shifting problems. Clutches usually squeal as the release bearing gives out, screeches if the disc has been scarred, or just doesn't engage properly/slips when you launch the car as they wear out over time.

It seems like your synchro is screwed.. or worse. You will likely need to have your transmission rebuilt to fix the problem. If the car wasn't like this from when you first had it, then you also need to work on your driving skills/habits or remember to change the oil at the required intervals.

The car "jerking" and stalling in the middle of the street is odd though. It's called "bucking", and it's a sign that your clutch is gripping fine. Usually drivers new to manual transmissions have this problem as they engage the clutch poorly (too abruptly) and cause the car to buck. If you're not doing anything wrong, then it's possible that there's something wrong with the clutch master cylinder (may need to bleed it), the pilot bearing could be broken, the clutch disk could be contaminated, etc.

I'm no expert though, and have limited experience with transmissions so don't just take my word for it hahah..
