I am in tears. I bought my BN1 in 1957. In 1958, the transmission gave out, and I had it repaired. New input shaft, new cluster, new second. I was told after it was done that a kit had been made available by the manufacturer, but my dealer didn't use it. It has been running great ever since, as I make it a practice never to allow the overdrive to shift in second. Driving home tonight I thaught there was a strange note to the exhaust in second. the next time I used second, there was a loud expensive repetitive sound. Are there any BN1 transmissions out there? (I want to keep it original).
