P0736 OBD Error Code: Problem & Solutions

<<See All OBD Codes

If you are experiencing unusual response of the throttle, lack of power forms the car engine, impact on the fuel economy, engine stalling and harsh shifts and frequent illumination of the Check Engine Light, it might be an indication of the OBD Code P0736 error.

OBD-II Code P0736 is defined as a Reverse Incorrect Ratio.

OBD code P0736 is defined as “Reverse -incorrect ratio”, and is set when the PCM/TCM (Powertrain Control Module/Transmission Control Module) detects a problem while shifting into reverse gear, or while the vehicle is in motion with reverse gear selected. Note however that this code does not refer to a gear ratio as such, since most automotive applications have only one reverse gear ratio. This code refers to a transmission’s inability to select reverse gear, a transmissions’ inability to maintain the reverse gear selection, or to a situation where the transmission’s actual speed does not agree with the transmission’s desired or expected speed while reverse gear is selected.

What causes this problem with the Reverse incorrect gear ratio?

• Dirty, contaminated, or degraded transmission fluid
• Low transmission fluid level
• Mechanical failure of transmission components
• Internal pressure losses
• Clogged fluid passages

1. Automatic Transmission Solenoid - Check and replace faulty transmission solenoid as it will not let the transmission system to function properly. Buy new solenoid now!
2. Transmission Control Module - Failed TCM can interpret the information wrongly and sometime cannot at all. Thus, replace faulty sensor immediately.
3. Automatic Transmission Sensor - Transmission sensors should be checked for failure and replaced at first instance. Buy new sensor now!
4. Engine Control Module - OBD Error Code P0736 can also be due to faulty ECMs. It’s better to get the faulty electricals replaced as soon as possible.
5. Powertrain Control Module - PCM problem can lead the wrong OBD code flashing and getting stored in the system. Thus, replace all faulty Powertrain related parts with us.
6. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to buy quality diagnostic tools.

Have a look at some ways with which you can correct the P0736 code:

• Transmission fluid replacement
• Transmission range switch replacement
• Repairing an open or short in the wiring harness or replacing it
• Park/neutral position switch repair or replacement
• Broken electrical connections repair or replace

If you are facing OBD error code P0736, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• Stored trouble code and an illuminated warning light
• Reverse gear engagement delayed, or may not engage at all
• Transmission slippage

Always take help of a trained professional to solve any OBD error problem and these problems can be highly technical and time consuming while diagnosing.

• The P0736 code should be diagnosed with an OBD-II trouble code scanner. A trained technician will look at the freeze frame data on the scanner to assess the code, and to check for the presence of any other trouble codes.
• The mechanic will begin by visually inspecting the electrical components in the transmission circuit. Any wires that are shorted, connectors that are open or corroded, or fuses that are blown will need to be replaced.
• Check the dipstick to make sure that the transmission fluid is not low and refill if required. Look at the fluid to determine if it is clean and replace, if needed.
• Smell the fluid to determine if there is a burnt odour. If the fluid smells burnt, remove the transmission pan to check for debris. Also check for burnt wiring and faulty circuitry.
• Inspect the transmission to determine if damage has occurred that will require extensive repairs.
• Check for Transmission Control Module and Powertrain Control Module faults that may require repairs, reprogramming or replacement. Although, it is rare butt still must not be rules out.

Common Mistakes When Diagnosing the P0736 Code

It is important to follow the diagnostic steps properly to correct the OBD code P0736 error. Following are the problems that can be missed and are mostly the reason for this kind of problem:

• Internal transmission failure
• Powertrain Control Module (PCM) failure
• Transmission Control Module (TCM) failure
• Transmission valve body failure
• Wiring issue and connector problems
• Automatic transmission solenoid faulty
