I have noticed lately that selecting first gear when stationary sometimes results in the car shuddering and there is a slight clunk. Almost like I missed the gear. It doesn't happen all the time and as far as I can feel I always manage to fully disengage the clutch.....any ideas...I'm worried there might be an engine or gear box mounting issue, or possibly a problem with the sincro......the last time I had a similar experience was with my Chevette in the mid eighties...this was due to a thrust bearing failure, but I can't see that a front wheel drive car would have the same (??).....
