It is a CVT transmission meaning a automatic and manual.
The first day I started having the problem my car would not crank the first time I turn it over it would crank the second time. I had a guy tell me after he tried to boost my car off that he thought it was my starter, so my son change the starter and when he took it down the road after taking the battery completely out the car was bucking and would not come out of first gear. Sometimes the motor will not book, but they are rpm's or run really really high still will not change out of first. Could someone please help?

You would also verify battery terminals are free of corrosion and installed properly. The thin positive cable is the one going to the relay box so if any corrosion there, you are going to have problems.

It sounds like you will have a code or two in the computer can you please run the codes to see what comes up?

Manual or automatic? If it's manual check fluid in trans make sure its 'full. Your shift linkage may be jammed as well causing this or maybe a cable or rod broke. There are two cables that control shifting so have a local pro look at it.

Transmission shifts fine when cold, but when engine temperature warms up it won't shift out of first gear. The problem seems to reset and go back to normal after the engine is off for about 20-30 minutes or longer. Transmission fluid has been replaced and it is very clean.

Hi,

Is the check engine light staying on when the engine is running? Also, there is a transmission fluid temperature sensor that can cause it to go into limp mode (basically what you experience).

Tell me if you have had the computer scanned to identify if there are any stored codes. Here is a list of OBD2 codes you may find of interest:

https://www.2carpros.com/trouble_codes/obd2

Let me know. If you haven't had it scanned, I feel that is the next step simply because it could be the A/T temperature sensor is telling the computer that the transmission is overheating, it could be a line pressure sensor, and several other things.

Take care,

Joe

When the car heats up after you drive it for a little while or sit in traffic it wont shift out of first gear then if you turn it off and sit for a little while it works fine.

Hmmmm. I see you asked last year about the same problem I'm having now.

My 2001 Max trans has began to slip intermttently, but my dealer tech says he can find nothing mechanically wrong with it. I had the fluid changed, it was not burned or dirty, and neither were there any fragments in it. If I turn the car off, then restart, the car changes gears as it's always done. Could there be a computer and/or sensor problem (but I've gotten no codes via service engine soon light)?. Thanks. Ray

I posted here just in case someone might see and know something about this.

I'm having this problem now. 720 is the code and it'll slip and not shift out of 1st/2nd gear turning the car on/off or letting it sit for a minute will resolve the shifting.

How did you repair this?

Shifting from second to drive at very low RPM’s the transmission “misses” shifting into drive at moderate to hard acceleration the transmission works perfectly. Have flushed the transmission ever 50,000 since new using B&G flush & conditioner and changed out two sensors. Was going to drop the pan and change the filter? The only time this issue occurs is when I accelerate approximately 10% or less. Any insight?

Hello,

This does sound like the revolution shaft sensor is out. can I ask if you replaced the sensor with an OEM unit? Lets run the codes to see. here is a guide with the sensor location in the diagrams below:

https://www.2carpros.com/articles/checking-a-service-engine-soon-or-check-engine-light-on-or-flashing

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Have changed the sensor in the past-worked for a while the when it went out I replaced it with a aftermarket part. I’ve just replaced the resister assembly and am due for a transmission flush anytime now. Would you suggest me getting a Toshiba sensor over the other manufacturers? And I had thought about dropping the transmission pan and changing the filter although I flush it every 50,000 as advised with B&G “quick clean. And conditioner. Thanks For the help.

Hey Ken I’ve got that part ordered and will install it upon arrival. The question about changing the transmission filter? Would you advise to? I’m sure those magnets are covered with “filings”? And is there any explanation about the IAC shorting out and frying the ECU? And/or is the “liquid” filled motor mounts tearing then shorting out and shorting out the ECU-as you see there has been many questions over the last(almost) 20 years keeping this vehicle on the road. Thank you

It is not shifting to third gear, and it is making a whistle sound and it is heavy after it gets hot.

This is sounding like an internal transmission problem, probably slipping under load, if you can, check the trans oil condition, if it is dark and smells burnt, you will be up for a re build or a new transmission, there is no magic fix in a bottle so do not waste any money with theses additives.

Serving the transmission is always a good idea. this guide will walk you through the steps:

https://www.2carpros.com/articles/how-to-service-an-automatic-transmission

I'm not sure what you are saying about the shorted ECU? Did something happen wires shorted or IAC? did you fix it or?

Yes Ken you’ve explained “drain and fill” but first my 2001 doesn’t have a plug?-And I’m thinking it’s about time to change the filter and clean out the pan although I’m not having the issues the other Maxima owners are! To be continued.
