Recently purchased a 2002 Protege5, it has about 180,000 miles. Its been having a transmission slipping problem though. O/D light is blinking and ABS light is just on. I replaced the transmission speed sensor on the top of the transmission next to the motor mount but it seems nothing has changed. Also scanned the OBDII with no codes showing up. Very confused and need help figuring out how to fix this. Only have pretty basic knowledge on cars but enough to be able to confidently replace what i need to. PLEASE HELP!!!!
