Transmission problems: 2004 Ford Explorer v-8 4.6L

When driving, the RPM gauge leaps and the vehicle lurches forward. I assume something in the automatic shifting is messed up. Additionally, when starting the vehicle and putting it in reverse, it makes a "clunk" noise and then lurches the vehicle back. It drives forward and backwards fine, but those are my issues. Any thoughts? Thanks

I'm not a transmission expert. To some extent a lurching can happen if something as simple as a vac line is off a valve on a transmission body but not so much the reverse issue.

I'd take it to a shop for diagnosis, or if you have forscan app and an OBDII dongle to connect to an android, IOS device, or PC, see if any diagnostic codes are set.
