Mercedes ML450 P0730 Incorrect Gear Ratio Code: Repair Costs for Sensor, Transmission, or Catalytic Converter
I'm experiencing a P0730 code on my Mercedes-Benz ML450, which indicates an incorrect gear ratio. I've already considered changing the transmission fluid, but I want to understand the repair costs if the issue is related to the transmission sensor, catalytic converter, or torque converter. Could you please provide estimates for each potential component? Specifically: - What is the typical cost to replace a transmission speed sensor? - How much does it cost to repair or replace the catalytic converter? - What are the costs associated with torque converter replacement? I'm aware that the issue might not be limited to one part, and further diagnostics are needed. However, I'd like to get a clear understanding of potential expenses before proceeding.
It's best to take your vehicle to an Autogearbox specialist for a proper diagnosis and accurate cost estimate. I believe the transmission speed sensor can be accessed without removing the gearbox, which would make repairs significantly more affordable. That said, the root cause might not be the sensor—other components could also be at fault. Pricing is difficult without a full inspection.
