P0733 on Nissan
Gear 4 Incorrect Ratio
P0733 on Nissan vehicles indicates gear 4 incorrect ratio. Au7o has documented this code across 1 Nissan model — most commonly on Titan. 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. Typical repair costs on Nissan range from $250 to $6,500, depending on the specific model and root cause.
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
