Hi Bookworm,
Thank you for the donation.
I would never recommend transmission flushing. A fluid and filter change would be the most you need to do.
As to the rpm fluctuating wildly and jerking, it is more an engine misfiring fault rather than the transmission problem. I would suggest checking the ignition system, spark plugs and related parts.
