Are you joking or what? 10,000 for a Super CVT-i K410 transmission? The side-mirrors for the post '05 Vitz cost around 15,000rs. Even if you do get a un-repaired transmission which is next to impossible it'll set you back at least 25-30,000rs.
The last time I went to Shershah which was about a year ago, I saw a 1KR-FE which the shop owner claimed had 60,000Kms on it, was paired to the K410 transmission. He was asking 85,000rs for the complete setup.
I don't know where you got the idea of 10,000rs for a complete K410 transmission from.
