Kia Troubleshooting Questions? Ask a Mechanic
Hello and welcome to JUST ANSWER my name is ***** ***** to assist you to your satisfaction. I cannot see or hear your vehicle so I rely on your patience and input to my questions so I can help you better. I read your notes and have a few questions before we proceed.
When you triy to shift gears , does it seem to grind the gears and is it in all gears or just one or two?
Unfortunately there is only one adjustment and that's the one you tried but it is for pedal height not slave cylinder travel. If it is not slipping that's one good thing
All though there is no adjustment for that you can try bleeding the system and measuring the fork travel. I am suspecting the syncros in the trans mission are worn. These are the rings between the gears inside that help moving from one gear to the other by matching speeds.If you drop some gear oil from the transmission you may see some yellow or brassy metal particles and that would indicate that very thing.
I just sent a description of what and how those rings work in your transmission.
