COMMON ERROR CODES ASSOCIATED WITH TRANSMISSION ISSUES
Illumination of the check engine light signals serious issues.
Many of these issues are related to the transmission system.
A mechanic can perform a computer analysis to reveal the problems.
Here are some common error codes associated with transmission issues.
P0715 Input Speed Sensor Issues
Your automatic transmission system uses the input & output speed sensor.
This is done to determine the gear that the TCM wants to be in.
If you see the code, then the TCM is not correctly calculating the shift pattern.
The transmission will go into the limp mode if this happens.
P0729 P0736 Gear Ratio Issues
These codes all report problems with the gear ratio of your car.
They report the same error but report it for different gears.
The TCM’s input & output sensors measure the speed of the input & output shafts.
If they are not moving at the right speed, then you will get these error codes.
P0613 ECM / TCM Incompatible
This a purely informational code, telling you that the ECM & the TCM are incompatible.
If you have this code, chances are that one of the systems has been recently replaced.
However, if you installed a used part, then it is not configured to work with the new part.
On modern cars, these systems are programmed to work with one specific vehicle.
Conclusion
These are the most common transmission trouble codes.
Take your car to an automotive repair shop to fix the issues.
