Nissan maxima transmission problem

https://www.youcanic.com/nissan-transmission-problems/

Your little hand code reader only reads Engine Control Modules (ECM ). You need to have a scan tool that has capability of reading Transmission Control Modules (TCM) in order to pull a code for your particular issue being stuck in 5th gear. I hope this helps you figure out the problem at hand. Jesus loves you, John 3:16-17 (KJV)

Brake pedal sensor to transmission has gone bad, or transmission is bad.

Hey i changed out both cam position sensor and the car is still stuck in 5th gear once it warms up. What could be the problem

The main ground wire brakes where it connects to the transmission. look under the battery carridge

I don't know exactly how the nissans work with their "limp" mode for what gear it goes into and such. This sounds like the computer is sensing a problem and going into the "limp" mode. Go get the code pulled to see what is says. If it has anything saying trans slipping or ratio problem then something internal in the the trans is wrong. Also, check the trans fluid and see if its burnt ( dark brown or black).

possible transmission speed sensor problem.

i had same problem it is your cam positioning sensor

This is most likely one of your cam shaft sensors. The reason your transmission goes to 5th gear and stays there is because the car automatically goes into "safe mode". This prevents you from running the car on high RPM's which decreases the chance of causing more damage to the engine.
Depending on the code you get from the check engine light, it will be one of the cam-shaft sensors or the crank shaft sensor. A code reader will answer that question.
Often the sensor just fails or oil gets into the connectors which prevents proper reading. This sometimes goes away temporarily when engine is hot but problem will return.
To replace the cam shaft sensors you are looking at approximately 30 min of work. Its a tight fit but not a difficult job.
Cam shaft sensors are about $80. Not sure how much crank haft sensor is.
Hope this helps, and good luck.
