MY 1989 nissan pickup Z24i has vibration issues at around 2400 rpm in every gear. Especially when it is warm it will vibrate at that motor RPM and then when I pass that rpm the vibration goes away. The vibration causes the motor speed to flutter at 2400 rpm when I shift gears. Does this sound like a timing chain issue or an issues with a leaking exhaust system?

SOURCE: gear shift

Do you hear a clicking sound coming from the shifter area everytime you hit the brake pedal, while the vehicle is is "P" park position?? There should be a clicking sound right by the shifter. That's the shifter lock solenoid. If that's not clicking you will not get the car out of park. Let me know what you found.

Check your intake and exhaust modules. I have a 1987 D21 and had the same problem (if I understand your post). I replaced the modules located behind the driver side headlights and it fixed the problem. Good luck! I hope this helps.

no should be same engine. check your engine mounts and tranny mount. how bad a vibration? sometimes after installing engine the trans gets shifted around and if mount was worn it will allow it to hit crossmeber and vibrate.
