Shifting into gear is difficult and once in gear it runs fine

Nice to meet you as well, most of the time when this happens it is because the shifter cable has stretched and needs to be replaced, this is a common problem. I have included how to change the part out in the diagrams below. You may be able to adjust the cable which is included in the instructions. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

Thank you, Ken L., for your hard work. I've tried the instructions you mentioned and after setting it up it's fine, but after a while I'm getting an unknown situation. I am currently disassembling the transmission and suspecting the torque converter. its old oil will be changed and cleaned, and it will be checked for broken gears and parts.

Please let us know what you find. We are interested to see what it is.

Hello dear. I disassembled the CVT and checked the torque converter, and because it has normal clean oil, I disassembled the valve body, suspecting it. Inside the upper body of the valve body, three long valves were stuck, and one small valve was completely stuck and was rebuilt and reassembled. However, while removing the cover, two pulleys were accidentally pulled from the shaft. How to configure it?

Can you upload a picture of the CVT belt and pulleys please?
