Hello all - first post! I have a Caterham R400 Superlight in the USA. It has a 2.0L Duratec and Caterham 6 speed. It has been a ton of fun, but I would greatly appreciate some help in diagnosing a transmission / clutch / shifter issue I am having. Most of the time, the car behaves normally with no problems. The problem occurs intermittently when coming to a stop then starting off again. When it does exhibit a problem, here are the symptoms: Clutch pressed, transmission won't go into gear Clutch released in neutral, and an obvious knocking noise occurs from the transmission / clutch area Yesterday, while the shifter was still in neutral, releasing the clutch caused the car to be propelled forward very slowly, almost as if it was partially in gear despite the shifter being in neutral. The strange knocking noise persisted while the car very slowly was propelled forward. Depress the clutch and the noise stops, and forward movement stops (shifter still in neutral). I move the shifter back and forth a bit in neutral with clutch depressed, then all of sudden the issue goes away again completely, it goes into gear just fine, and no more noises (until it intermittently happens again)Any ideas where I should start to diagnose this? I would love to get it fixed up and get back to driving and some track time! Thank you for any help!
