How do I fix code P0734?

How do I fix code P0734?

What Repairs Will Fix P0734?

1. Change transmission fluid / filter.
2. Repair or replace damaged wiring and/or connectors.
3. Repair or replace failed transmission or torque convertor component.

What is P0734 engine code?

P0734 code definition A P0734 trouble code indicates that an abnormality has been detected in the gear ration of one of the automatic transmissions gears, causing the storage of a code in the Powertrain Control Module (PCM) and illumination of the Check Engine Light.

How do you fix an incorrect gear ratio?

How to Fix

1. Check all electrical connections and wires that connects the sensors to the transmission control module.
2. Repair or replace damaged or corroded wires in and around the transmission control module.

What does gear 5 incorrect ratio mean?

Error Code P0735 is described as Gear 5 Incorrect Ratio. This refers to a problem in the fifth gear of the automatic transmission, usually caused by dirty or insufficient transmission fluid or issues in the solenoid.

How can you tell if a transmission solenoid is bad?

3 Signs of Transmission Solenoid Problems

1. Unpredictable Gear Shifts. One of the most common sign that one or more of your transmission solenoids are going bad is unpredictable gear shifts.
2. Inability to Downshift.
3. Delays In Shifting.

What causes incorrect gear ratio?

The incorrect gear ratio code may have several causes: Bad or dirty fluid in the transmission. Broken mechanical components within transmission. Internal blockage in fluid lines.

What does transmission fluid pressure low mean?

If the fluid is low, it should be assumed that there is a leak in the system, and the mechanic should begin searching for where the leak is coming from. If the transmission fluid level is normal, the mechanic should check to see if the transmission temperature sensors are faulty.

Can you drive with incorrect gear ratio?

Problems with the incorrect gear selection may cause drive-ability symptoms. The check engine light or malfunction indicator lamp will be illuminated as long as a P0730 is recorded in the ECC.

What can cause an incorrect gear ratio?

The incorrect gear ratio code may have several causes:

• Bad or dirty fluid in the transmission.
• Low fluid in the transmission.
• Broken mechanical components within transmission.
• Internal blockage in fluid lines.
• Bad transmission control module.
• Problem with the torque converter clutch.
• Problem with the shift solenoids.

What happens when shift solenoid goes bad?

a problem with one or more of the solenoids can cause a lack of pressure, resulting in hard, soft or delayed shifts. a failed shift solenoid can also cause transmission slippage, where your engine revs faster but the car stays at the same speed.

How much does it cost to replace a transmission solenoid?

To replace the solenoid in your transmission, you will pay anywhere between $150 and $400. The labor should take 2-4 hours and cost you $60-$100 per hour. The parts can be as little as $15 or as much as $100 for each solenoid.
