transmission shifts perfectly in forward gears but no reverse

Good morning,

The fact that it moves perfectly forward tells me it is not an electronic issue.

The reverse is a mechanical application inside the transmission. It is the application of a clutch and a band.

Chances are one of them has failed and not allowing reverse. This will require removal of the transmission and internal inspection for no reverse.
