Remove oil pan jeep liberty 02 3.7 - 2002 Jeep Liberty

SOURCE: 02 jeep liberty won't shift into 3rd or 4th gear.

Ratio codes generally indicate a pressure loss & slipping which the computer reads as a gear ratio problem. Likely you need a rebuild.

Instructions can be found in any basic manual but the simple version is to remove anything obvious that will be in your way (starter, trans lines etc). Disconnect both engine mounts and raise engine to get better clearance (watch stuff on top so you don't break anything) I usually stuff a couple of 2x4 wood blocks between engine & mounts to support it. Remove all pan bolts and take it down (remember pump pickup will interfere) Do what you need to do, then reverse process.

SOURCE: o 02 jeep liberty oil pressure light stays on

A couple of things could be wrong a bad oil pressure sensor, a short in the sensor wiring,low idle oil pressure. Checking this is simple on some models.

While disconnecting the sensor from its wired connector and the light stays on is a short in the wiring, if it stays off its hopefully a bad sensor. Before just replacing the sensor I would either buy a gauge to check the pressure at the engine and thus checking the sensor also. I HATE DUMMY LIGHTS!!!

Gauges are simple, easy to install and easy to see a problem before engine damage occurs. On the bad end of the spectrum of possible problems the oil pump may be worn out, or even the engine may be worn out to the point oil pressure loss at low idle or while oil is sloshing forwards at stop signs.

Hope helped with this. remember rated this help.
