P0735 on Jeep
Gear 5 Incorrect Ratio
P0735 on Jeep vehicles indicates gear 5 incorrect ratio. Au7o has documented this code across 1 Jeep model — most commonly on Grand Cherokee. This code means the Transmission/Powertrain Control Module detected an incorrect gear ratio in 5th gear. By comparing input shaft speed to output shaft speed, the module verifies each commanded gear; when the 5th-gear ratio is wrong, P0735 is stored. This typically means the transmission is slipping or failing to lock into 5th gear due to fluid, friction, or solenoid issues. Drivers may notice slipping at highway speeds, RPM flare, poor fuel economy, or limp mode.
Common Causes of P0735
- •Low or degraded/burnt transmission fluid
- •Slipping clutch packs or worn friction elements in 5th gear
- •Stuck or faulty shift solenoid
- •Valve body / internal hydraulic leak or restriction
- •Worn or failing torque converter
- •Faulty input or output speed sensor
- •Internal mechanical wear inside the transmission

- 2004 545RFE Intermittent Low-Line-Pressure or Gear-Ratio DTCs — Check TCM Build Date2004
DaimlerChrysler TSB 08-016-05 describes an internal TCM circuit fault that may cause an intermittent low-line-pressure or gear-ratio DTC and limp-in on a specific 2004 WJ/WG Grand Cherokee population. The vehicle must have the 545RFE (sales code DGQ), a 4.7L or 4.7L High Output engine, and fall within the bulletin's April 7, 2004 through February 27, 2005 vehicle build range. Suspect TCMs have date codes 0984 through 0405. This is not a universal 1999-2010 transmission-overheating/shudder diagnosis, and it does not justify buying filters, fluid, a cooler, valve-body kits, or a solenoid pack from the symptom alone.

What does P0735 mean on Jeep?▼
P0735 stands for "Gear 5 Incorrect Ratio." This code means the Transmission/Powertrain Control Module detected an incorrect gear ratio in 5th gear. By comparing input shaft speed to output shaft speed, the module verifies each commanded gear; when the 5th-gear ratio is wrong, P0735 is stored. This typically means the transmission is slipping or failing to lock into 5th gear due to fluid, friction, or solenoid issues. Drivers may notice slipping at highway speeds, RPM flare, poor fuel economy, or limp mode. On Jeep specifically, this code is documented across 1 model.
