P0733 on Jeep
Gear 4 Incorrect Ratio
P0733 on Jeep vehicles indicates gear 4 incorrect ratio. Au7o has documented this code across 1 Jeep model — most commonly on Grand Cherokee. This code indicates the transmission control module found that the actual gear ratio in 4th gear is outside the acceptable range for that gear. It is detected by comparing transmission input speed against output speed while 4th gear is engaged. A mismatch typically signals the transmission is slipping in 4th gear or that a control/hydraulic fault is preventing proper engagement.
Common Causes of P0733
- •Low or contaminated transmission fluid
- •Worn 4th-gear clutch packs or bands
- •Failing shift solenoid for 4th gear
- •Valve body or line pressure issues
- •Internal transmission mechanical wear
- •Restricted transmission filter
- •Faulty input or output speed sensor

- 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.
