I sometimes get shift shock when putting in 1st gear after coming to a stop. I was able to repeat the symptom few times with the following sequence of actions:

- come to a complete stop with the gear in neutral and clutch released
- wait few seconds and then push the clutch and put the gear in 1st. Over 30% of time, I hear and feel a small transmission "shock" - similar to the sound and shock you would feel when you quickly release the clutch. At first, I thought the clutch wasn't pressed all the way, so I made sure to REALLY push down on the clutch before shifting... the result is the same. there is a minor shock when putting into the first gear AFTER you come to a stop from a cruising speed.

I don't have a problem if I come to a stop with the gear in neutral but keep the clutch depressed and never release it. If I keep the clutch pushed in while I wait for the light to change, the 1st gear goes in smooth and soft without any noticeable "shock". But this is very inconvenient, and despite of soft Kia clutch, it does tire out the leg.:(

Sometimes the 2nd gear doesn't go it smooth either... As the other posters mentioned, I may ask the dealer to check out the clutch master cylinder the next time I visit them.

Bro, I'm wondering if you manage to find what's causing that problem and what did you do to fix it. As you know, my friend is having a similar scenario like yours on his car and it's kinda confusing why that shift shock is happening. I'm kinda hoping you could share some solution or any inputs on what did you to resolve this problem on your vehicle. I'll appreciate any possible solution to this.

Try doing this:
-When you go to a complete stop. Engage the clutch and put into neutral.
-Then disengage and re-rengage the clutch, while still being in neutral.
-Finally, throw it into first.

If it doesn't give a "shock" (your going to have to do this over and over to make sure it's solving the problem) then your slave cylinder could either be low on fluid or needs to be blead. IMO, it sounds like a clutch issue and possible it not wanting to sync up with the #1 shift fork, hence why 1st and occasionally 2nd kinda suck.

It kinda sounds like what happens when you put an automatic car into drive on a cold day. It delays, then it kinda makes the car "jump" a bit. Is that what it feels like? (I understand your car is MT, just trying to understand what the car is actually doing)

I get the exact same thing in my 6speed SX koup - almost jolts the car forward a little bit.

Doesn't happen ALL the time, but I can make it happen if I want to.

^ does that happen when you go you are downshifting or when you are at a complete stop? If it's when your downshifting, it's the ECU's attempt to protect the transmission (kinda like traction control, where it will "kill" power) also called the Transmission Control Module. But if your at a stop and it's doing it, then it's your slave cylinder (your car shouldn't be moving at all if the clutch is truelly engaged).

@elijah
The issue has not been fixed despite of visiting the dealer twice, because it's hard to replicate the issue when at dealer.

First there is an understandable confusion in this thread as to when a clutch is "engaged" or "disengaged". A clutch is engaged when the clutch disk is in contact with the flywheel (pedal released). The clutch is disengaged when the clutch disc is not in contact with the flywheel (Pedal depressed). I tried to duplicate the "shock" but was unsuccessful. I developed a habit many years ago while driving old British sports cars with no 1st gear syncro. After coming to a stop in neutral with the clutch pedal released, when I am ready to go I depress the pedal then shift into 2nd gear before shifting into 1st gear. Try this and see if it works.
