P0730 on Renault
Incorrect Gear Ratio
P0730 on Renault vehicles indicates incorrect gear ratio. Au7o has documented this code across 1 Renault model — most commonly on Koleos. This code means the transmission computer detected that the actual gear ratio (calculated from input vs. output shaft speeds) does not match what it should be for the commanded gear. In other words, the transmission isn't delivering the correct gear, which often shows up as slipping, flaring RPM during shifts, or being stuck in the wrong gear. It can stem from internal mechanical wear, low or contaminated fluid, or faulty solenoids and sensors. The vehicle may shift harshly or enter limp mode. Typical repair costs on Renault range from $300 to $3,500, depending on the specific model and root cause.
Common Causes of P0730
- •Low or contaminated transmission fluid
- •Worn clutches or bands (internal slipping)
- •Faulty shift solenoids
- •Dirty or sticking valve body
- •Faulty input or output speed sensor
- •Internal hydraulic/line pressure problems
- •Torque converter problems
- •General high-mileage transmission wear

Renault Koleos(1 issue)
- CVT Judder and Slipping2008-2024
The Jatco CVT in the Koleos develops judder, slipping, and overheating symptoms. The CVT belt and pulleys wear under the heavier SUV load, and the fluid degrades more rapidly than in lighter applications.
