I just bought a Birkin built around 2010 by Texas Motor Works.
It has a Duratec and a type 9 trans with close ratio gears.
The transmission needs refreshing which I am happy to perform myself, but I wonder what the best source of parts is. Should I call TMW and buy from them, assuming they even sell trans parts? Or is there a 3rd party that makes/sells the gears and such for the trans that TMW sold with the car?
In case it might matter, I am in southern California.
Thank you for any advice.
