complete new transmission is $2017
Honda Automotive Parts.
Car-part.com has a few that have 10,000 miles and a whole bunch that have 50,000 miles on them.
I had my first vx transmission have the main bearing go out at 230,000 miles and I drove it for another 5,000 or so before replacing it with a $150 used, 100,000 mile transmission, my current vx has 216,000 miles on it and the transmission is very smooth and quite.
I suspect that what made my first tranny go out at 230,000 miles was the lack of mtf changes, when I bought it the owner at the time said the only thing he replaced on it for 100,000 miles was tires, exhaust and engine oil changes.
