Hello. My Nissan 2012 model 1.2 Micra automatic vehicle vibrates at speeds of 50-60 km. When I take my foot off the gas and press it again, this problem goes away. When we take it to the repairman and connect it to the device, it gives FLUID PRESS SEN/SW B error (P0846). What could be the problem?
I had the code cleared after switching the step motor today, it was driving ok for about 2 miles then the original symptoms started slowly reoccurring again. It isnt as bad as before switching the stepper motor but you can tell the acceleration isnt what it should be, im wondering if its gonna take a little more driving like you mentioned towards the end of the video to fix itself?
@@streetkred2214 probably but is hard to tell with this Cvt transmissions . Mine was driving better and better after the stepper motor replacement. Good luck
@@isaiahavinarosas8509 if that’s the case, you would have to start all over and make sure that the lever doesn’t fall out. Everything has to be put back the same way in the video. Good luck You got this
tienes que reprogramar la transmision cuando cambias esa pieza? dos mecanicos que eh consultado no quieren hacer el trabajo yo soy mujer y quiero hacerlo yo la mia es una nissan rogue pero es el spepper motor que necesita tambien
@@EdwinM728 muchas gracias desafortunadamente mi hijo compro un carro y lo estafaron el carro no acelera y me tira ese codigo e consultado 3 mecanicos y como es en la transmision no se atreven a hacerlo, asi yo lo pienso hacer lo veo mas facil que otras cosas que eh hecho en mis carros, soy aventada jaja. crees que es necesario cambiarle todo el valve body o solo el stepper motor es suficiente? muchas gracias
@@mombux pues honestamente se me hace difícil darte dirección porque se me acaba de dañar de nuevo y no con los mismo síntomas ahora vibra muchísimo. Ya decidí buscar otra transmission. A la verdad que son unas basura de transmission ☹️ pero este es mi situación quizás te funcione cambiándole las partes a ti. Suerte 💪🏻
@@mombux pues si me funciono estaba como nueva pero parece que se daño otra cosa mas adentro 🤷🏼♂️ ya luego hago el video de como la cambio por otra 🤓 ni modo
@@renearias9791 after working just fine for a while one day I really stepped on it to go fast and the transmission broke the variators or the steel belt not sure but its shot now looking to get it rebuilt. This car was neglected before I got it and it shows cant win them all I guess so it did worked.
Did you put the gear to park or neutral before taking apart the valve body? Thanks for the hep.
I left it in park. 👍🏻
@EdwinM728 thanks for the help

I'm not sure but had you tried replacing the fluid and filters.
@ yes ıt has changed but the problem fontunues
@@meryemozbekli6484 I would change the pressure switch next, but that's what I would do. good luck this CVT transmission are terrible.
@@EdwinM728 ok thanks
Very nicely and thoroughly explained and presented video! What are the torque specs for the valve body bolts?
I think is 70 in-lb.
45lbs on 10mm

How many quartz of cvt fluid did you use to fill it up again?
About 5
Does the circular bushing go on the top or the bottom of the valve body?
It goes through it I don’t know the top or the bottom.
Nice job 👍
What were your symptoms? Did it limit reving the car in park mode?
Not in park but in drive it did.
Do you need any programming ?? I replaced step motor still running bogus , mechanic says I need to replace TCM
@@gabeonb when I did this it was running good with no programing.
Your oil looks new. Was it recently changed?
Yes prior to this I changed the oil and filters.
Hey bro what should I do if that lever in the end came out and doesn’t wanna go back in??

@@EdwinM728 I got new step motor and lever in 2012 CVT still ain’t work🥲
@@EdwinM728 thanks for the video boss🙏🏽
@@isaiahavinarosas8509 your welcome. Good luck 💪🏻
@@isaiahavinarosas8509 that sucks bro. This cvt are very problematic. Good luck

Hola yo no la programe, cuando le borras la luz de check engine con el scanner la transmission se empieza a reprogramar cuando la conduces.

Is the stepper motor still holding up?
