My car will only go in reverse. When you try to go forward, it won't go into gear. This happened suddenly, with no indication of any trouble at all. No codes.
Do you
have the same problem?

Good morning,

Since you have reverse, that means the torque converter and front pump are good.

The forward clutch pack or 1 way roller clutch has failed not allowing engagement of the forward gear.

The transmission will have to be removed, inspected and most likely rebuilt or replaced.
