The issues I was having were: if I was moving in first gear i could accelerate but then when I took my foot off the accelerator and let the engine do the braking it felt as if the engine moved slightly and the gear got stuck slightly so when i down clutched it would be quite hard to pull it out...
Hello did you ever find out what caused this? I have exactly the same problem that you are describing and need to fix it I think it’s the lower engine mount but just wondering what you discovered.
