I need to go on record to take back what I said about the 41 tooth metal gear replacement - I blew up 5 metal gears (2 in one day). It is not the answer to the transmission problem on the Kyosho car.
The answer is the Ipanema Blackhawk Transmission. I put mine in 4 months ago and since then I have had zero transmission problems.
Sorry for the bad info but at the time I wrote the post I thought the metal gear would work.
