I have the car listed above, and it has no reverse, and the transmission will not shift into neutral. When i shift into neutral it drives forward. When i drive it i don't feel it slipping or anything weird. No engine light on.

This could be a couple of things. So, we need to start with checking the fluid level and condition to find out if there are any issues with this.

Also, we could have multiple issues, so we also need to adjust the shift cable just to make sure this is not the issue.

Please run through these two things and let's see what happens. I attached the process from the manual below on how to do this.

Let me know if you have questions. Thanks

If the linkage and fluid is fine and we have no reverse and only drive, then we most likely have a stuck valve in the valve body.

I am attaching the process below but if it were me, I would remove it and check how each of the valves move in each bore.

Those that are sticking, use emery cloth to clean them up so they slide easily.
