2000 Volkswagen Passat gearbox

My car had an accident and after repairs the Gearbox selection became a problem. Only one gear is now driving and others are not selected. My Auto electrician diagnosed the car and found out that the gear Brain box have an issue. How can i repair it.

More likely a replace rather than repair.
By “ brain box” I guess you mean the processor that controls the transmission.
“Gearbox” do you mean automatic transmission?

Dears
The Brain Box part number is 8D0927156AS and VIN : WVWPD23B6YR229488.

I need a link to getting new or refurbished one.

Regards

Did your insurance cover the repair? If so, did you tell them about this follow-on issue?
