The Indy shop (they called theselves master technicans with 30 years exp and well-known shop in my area) made a mistake and blamed the TC.....

Also, the seller didn't know about LWX 500 well and sold NV125 without the shaft that connected to the transmission. That was the reason why my X5 didn't move at all..

I don't blame the seller because every one include Ebay sell NV125 without the shaft that connected to the transmission.

Now mine is now working well, now.

Edit
The seller's customer support was smooth so far. I will post more details later.
