The Most Common Trouble Codes for Transmission Problems:

The Most Common Trouble Codes for Transmission Problems: If your Check Engine Light has come on, there are a number of conditions that could be causing it. Many are related to the transmission.

Mechanic can perform a car diagnose that will reveal the problems that can be causing the Check Engine Light to come on in the form of alphanumeric codes known as P codes. The following are among the foremost common P codes:

P0218: Transmission over temperature condition

Your transmission is overheating. Some vehicles have a touch light which will say “trans over temp,” but not all vehicles have this feature. This code could mean that the fluid sensor must get replaced , but it could even be something much more complex, especially if amid other P codes.

P0614: ECM/TCM incompatible

This is another purely informational code, telling you that the ECM and therefore the TCM aren’t on speaking terms.

If you’ve got this code, likelihood is that that one or the opposite has been recently replaced, and if you installed a second hand part, it’s not configured to figure with the newer part. On newer vehicles, these parts are programmed to figure with only one specific vehicle, and can’t be programmed to figure with another.

P0700: Transmission control module malfunction

Again, this is often an informational code. With most vehicles, the TCM is that the only computer which will activate the check engine light. If there’s a drag preventing the sunshine from approaching , you’ll see this code.
P0706: Transmission range sensor circuit range/performance

P0706: Transmission range sensor circuit range/performance

The transmission range sensor tells the TCM the position of the gearshift . It also contains a neutral safety switch, which ensures that you simply can only start your car in neutral or park. This code could indicate corrosion or other problems within the transmission range sensor.

P0715: Input/turbine speed sensor circuit malfunction

Your automatic drive uses input and output speed sensors to work out whether your transmission is within the gear that the transmission control module (TCM) wants it to be in. If you see this code, it means the TCM isn’t correctly calculating the shift pattern.

You’ll usually find that the transmission goes into “limp” mode if this happens. A corroded connector or a drag with the wiring might be the matter , and therefore the usual solution is to exchange the input speed sensor.

P0720: Output speed sensor circuit malfunction

The speed sensors tell you ways fast your output or input shaft is moving. If the TCM can’t read this information, your speedometer won’t read accurately. The output speed sensor may have to get replaced .

P0729-P0736

These codes all report problems with the gear ratio. the sole difference in these transmission trouble codes is that the gear that’s being identified.

They’re all reporting an equivalent error, but they’re reporting it for various gears. The TCM’s input and output sensors measure the speed of the input and output shafts, and if they’re not moving at the proper speed, you’ll get these transmission trouble codes.

Most of the time the matter is as simple as low transmission fluid, although it could also indicate problems with the converter clutch or a shift solenoid if combined with other P codes.

The converter turns the engine’s rotational speed into a twisting force to propel your vehicle, and delivers additional gear ratio when driving at highway speeds.

A solenoid regulates the converter clutch, and if you see this P code it could mean that the solenoid is corroded or otherwise damaged. If that’s not the case, then it might be a drag within the wiring round the solenoid.

P0750-P0770

These codes all relate to shift solenoid failure. Your TCM tells your transmission how and when to shift by opening one among these solenoids to permit transmission fluid to pass into the transmission’s hydraulic control section for the precise gear. If one shift solenoid malfunctions, the gear that it’s intended to regulate won’t work properly, if it even works in the least .
