The car is a 2002 rsx base model with automatic transmission. Like title said the car wont go over 25 mph. After that the engine just revs but wont go any higher. Anybody have experince with a problem like this thanks.

 

It could be a few things ranging from a bad wiring harness or connection to the transmission, a failed solenoid in the transmission, a mechanical failure in the transmission, low transmission fluid, or a broken speed sensor.

 

i post video here you can see what you think, I reset the ecu and it went over 25mph but its have a hard time shifting to next gear in automatic mode.
