Jeep transmission problems are nothing new to Fiat Chrysler Automobiles, the manufacturer of Jeep vehicle lines. The automaker has made several powertrain and hardware refinements, recalls, software updates, and even full transmission replacements.

Low transmission fluid level – Low transmission fluid level can cause several issues, including erratic shifting, no-shifting, delayed shifting, strange grinding noises, limp mode, and even checking the engine light to come on.

Faulty Torque Converter – This can cause the Jeep transmission to slip in all gears, shudder, and even overheat.

Worn Bands – Can cause delayed shifting, shifting at high RPM, harsh shifting, no gear at all, and no reverse.

Shifter Module – A faulty shifter module or cable can cause the transmission to get stuck or not go in the selected gear.

Defective Valve Body – The valve body is complex and can fail in several ways. Depending on the competent that fails, it can cause limp mode. The transmission may not shift at all or harsh shifts between gears or specific gears.

Faulty Vehicle Speed Sensor – If your Jeep has developed a harsh shift or is stuck in emergency mode (limp mode), the vehicle speed sensor (VSS) may be the problem. Sign from the VSS is sent to the Powertrain Control Module (PCM), and the last signal can cause one or more of the previous systems.

Brake Light Switch – A faulty brake light switch can prevent the shifter from moving out or back in Park.

Low Battery Voltage – In rare cases, the low voltage can trigger the automatic transmission to get stuck in limp mode.

PCM / TCU / ECU Software Issue – Software issues can cause erratic shifting or downshifting issues. Transmission may shift too late or cause gears to drop unexpectedly. This is a common problem for your particular transmission; a Jeep dealer may have a software update to fix such shifting problems.

Wire harness – Damage to the wire harnesses from ECU / PCM to the transmission housing can cause shifting problems. For example, you may not be able to shift at all or go in gear.
