Rpm go high but no speed

Question

When i was driving in high at 60mph and then when i keep pushing the pedal gas suddenly the rpm go high like 7000rpm but didnt pick up speed i mean no speed at all and i stop on the side and back to normal again it work again but the service engine soon pop up and i go to auto zoned to diagnose my car and they got the code its P0720 and P1574. Probable cause - open or short circuit condition and failed vehicle speed sensor and i change the speed sensor and reset my car to remove the SES light, and its happen again the rpm go high and no speed but the SES light didnt pop up this time no light on the dashboard. Idk whats the problem they said the problem the one that the hole where you connect the speed sensor or the transmission.

Hi there,

If replacing the speed sensor hasn't solved the issue, it's likely a wiring problem. Here is a list of other possible causes.
