My suspicion has always been that the synchros weren't working properly, but I'm no transmission expert. I have driven manual transmission cars ranging from mid-60s British sports cars, to a Porsche and numerous domestic cars over the last 45 years without a problem. I even had a couple of 5-speed Fords that had over 200,00 miles on them in which I had no problems with the transmissions, so I don't know.

I guess the first step will be to take it to the dealer to have them evaluate it. Knowing how these businesses operate, I'm anticipating having to fight with them to get them to acknowledge there is a real problem. Has anybody here had to go through the legal process to get Nissan or its dealers to do the right thing in cases like this?
