Speed senior or bad transmission?

1998 Honda accord 2.3 automatic transmission 4 cylinder

Car shakes a bit and the car would go to 60mph for awhile before the rpms randomly jump high to 5-6000 and id have to let go of the gas and continuously doing it. Then when it is at 20mph it won't go faster than that and the rpms are still going high, transmission has fluid and it looks good. But i'm betting its a transmission issue but i'm clinging on hope its a speed sensor

When i was passing a speedometer on the high way it read my cars speed erratically from 57, 89, 5, 48. No car was behind me and my speedometer said i was going 25 and my speedometer is 5mph less than what i go

Transmission or speed sensor? I truly hope its the speed sensor. It only costs 8$ and i onlyhave 40 in my account. I'm broke and been on the shoulder on the highway since 2am. I've been crying my eyes out. I have no one to cal and i don't have AAA.

That reader board isn't going wonky because of your car.

"before the rpms randomly jump high to 5-6000 and id have to let go of the gas and continuously doing it"
"when it is at 20mph it won't go faster than that and the rpms are still going high"

Clutch slipping?
