Transmission only has park, reverse, and neutral, won't go forward.

It sounds like the forward clutch pack is bad. When's the last time you serviced the transmission? The transmission should be serviced every third oil change.

We should run the codes because it sounds like the first gear shift solenoid is not working, this guide can help, and I have included how to change the shift solenoid out in case a code is present for it.
