Please friends i notice that my Honda crv 2002 car don't engage in forth gear anymore . the transmission is automatic i have driven it just for 8 months. sometime when i engage the gear, it will take longer to respond. when it does the e engine will jack and vibrate heavily and D light will blink continuously . My mechanic has ran out of idea . i don't know any Honda service center around here in onitsha pleas advice me on how and what to do. thank

check if ur overdrive switch is on. if it is, turn it off.
