| Post subject: | 05 Liberty Transmission Problems |
My girlfriends 05 Liberty is having issues with the Transmission. It was making a whining sound and I found it to be coming from either the Transmission/Torque Converter. The other day it threw a P0700 code(Transmission Control System Malfunction) and a pending P0740(Torque Converter Clutch Circuit Malfuction.) Has anyone had these issues or what to do? Should I replace fluid and filter or just take to mechanic? The transmission does not seem to slip out of gear or anything just maybe a little shudder at highway speeds. Thanks! |

Mileage? Depending on when the fluid was changed it may be a good idea for a fluid and filter change, if you do this make sure they reflash computer so the trans can relearn things. |

has it ever had its fluid changed before? If not there is a chance that the trans is about to go out, or it could be simple. If its close to 70K take it to the dealer and see if the 7/70 warranty will do anything for you. |

Some would say this is overkill, but I change my transmission fluid and filter every 30,000 miles under normal conditions. On my Dodge Cummins, I change it every 15,000 miles. If I were towing with my KJ or off-roading, then I would change it every 15,000. Also, I would run a good synthetic ATF………….. Such as AMSOIL. Also, you could always upgrade to a better TC and add the transgo correction shift kit, which makes a noticeable difference in how she shifts.
