To Fabian: AWESOME VIDEO FABIAN. The video was simple, easy to understand, to the point, and definitely educational. And you're a very good presenter of material. To those reading the comments: After seeing this video, I contacted Sunbelt by phone to inquire about purchasing a stepper motor for a Nissan Murano. Not only was I lucky enough to to speak with Fabian himself, but also got some very helpful information and guidance from Fabian. It was definitely a priceless encounter.
Favian was an amazing help. No one in my area (North Georgia) works on these CVT transmissions, they only replace them. He understands them and all of their components. He may be able provide an affordable fix without full replacement. The videos are such a great help and resource! Very encouraging.
I have a problem it’s like my step motor stops with the neck all the way out.. and it’s connected to the valve body on the vehicle .. pls any suggestions.?
Love the content. So recently my 2013 maxima has no check engine light on, no trans codes either. I did notice from 20-30 mph the trans stutters but as soon as i let go off the gas and press it again it goes smooth. Then when im going 60 and slowdown from 40-20 its like rumbles. Could this be a bad stepper motor?
Sir, my Nissan sylphy 2.0 2008 p1777 show out and stuck in first gear,, can't change to higher gear Take out the stepper motor measure ctr to 2nd wire 16.3ohm and ctr to 1st wire 31.3 ohm Is that stepper motor issue??? Thank you
Hey Fabian; writing you from Jamaica. I have a 2010 Nissan Lafesta Sport. My problem is with the stepper motor. I replaced the motor but the problem persists. I need to know how do I check to see if current is going to be motor.
What controls the stepper motor? TCM or ROM? 2012 Maxima REOF09. Scanner reports motor is at step 196 and desired step is same. changed computers and same thing. stepper motor at 196 and stays there.
I have a P1777 code for stepper motor circuit where is the circuit located so I can fix the problem??? This is on 2007 Nissan Murano S is this part of the connector?
Hi Guys from sunbelt, I am in great trouble as my Suzuki Kizashi CVT gives an error P1816 that is Stepper motor malfunction. Now problem is that I couldn't find the stepper motor anywhere in India. Can anyone help me with it.
Very good video. Hey Thanks for doing it. Had same problem and exactly the same mosfet and i did it my self Guess what? Boom!!! Works like new again. Thanks man
Great video. I need help. 2009 Nissan Murano. Transmission Range Sensor A? P0705 code. I can put it in PRNDL but the cluster only shows “P” and “N”? I changed the stepper, fluid and filter but no different. I can send a video of my valve body if you send an email
I have a 2011 Nissan Rogue all out of the blue it will not move forward or reverse could it be a stepper motor I don't have a obd tester. any help would be great thank you. Al

Hi! Fabian, thank you for such amazing video. I have a question I was driving my 2008 Nissan Sentra CVT and the sudden the speed went down to 40 mph abd lost force, I scanned and it’s reading code P1777, which means stepper motor issue. Do you think I should change the stepper motor? Also a mechanic told that I can use the old transmission fluid if I replace the stepper motor, it’s that true? Thank you for your feedback
Hi Ernesto!! We are glad our videos are helpfull. We can certainly help you. Write to our email info@sunbeltvalvebody.com asking for tech support or visit our website sunbeltvalvebody.com. Thank you
Thanks for the video. Have you guys ever seen a sticking stepper motor? I have a weird downward lope/momentary loss of power in my Altima. Drops from 4k to 2k and goes right back up. Takes about one second. I’m sure you get bombarded with questions but I’d really appreciate your opinion. If you see this. Thanks sunbelt.

I just got the P1778 code for stepper motor on 2012 Nissan Altima. (i believe JFO11E) Just pulled it all apart and checked resistance like you did in your vid. Checked harnes for shorts, its all functioning properly. Checked the 4 coils and all 4 are at 15.5. Only thing i cant do is electrically try it, because i dont have the controller to test it. I believe the stepper motor is ok...but what i did notice was the ratio control valve, that attatches to the motor, seems to not move freely within its bore. It feels a tiny bit sticky. Could this cause the code for stepper motor? If so what is the remedy for it? I looked at valve bodies online, and looks like none of them come with the ratio control valve. So im assuming you must need to use it from original. But what if it is not within spec? It would cause issues on new VB...is there a way to bore or hone the original bore for the valve? Symptoms are the vehicle shifts or "varies" up till about 45mph, then holds the rpms around 3K but wont upshift. Then it sets the code. Hoping for some help. Thank you kindly!!
@@ezy123abc Yes i did figure out the issue...The trans was shot! Replaced it with a quality used one, and have had no issues what so ever. The pulley doesn't travel correctly, and it causes the stepper motor code.
Splash@ so how we know if too late the pulley inside mess up and transmission is shot … possibly low fluid or no service transmission that why it got shot
Where can I get this stepper motor for the Nissan Murano z50 CVT, Built 2006, European version. With shipping to Germany? There a many offers but I think it's very pur quality and Nissan does not support this part. And please tell me, can I just put it in without get the position of the old stepper motor or do I have to get it manually to the same position as the old one - when I will change it? Thank you very much and Best regards from Germany
Hi there, I checked my old and new stepper motor and both measured on the outside coil (middle wire and outest wire) 28 ohms… and the other coil is at 14… does that mean my old and new one are broken?
Hey Fabian I have a 2008 Nissan Altima 2.5 S I'm I'm trying to find a reliable Step motor replacement for my car. But I'm not sure about the part number. I don't want to get one that doesn't fit. Do you know who sells them that can fit my car? Thanks!!
Hey George, I have found it hard to get the actual part number for the step motor as it is not an individual part that Nissan sells. It is usually bundled with a valve body, but not always. I ended us using my transmission number JF009E RE0F08A to find the part. I got it (OEM part too) on ebay from seller tranzmissionpartsusa. Good luck!
@@Eric-hk5xt Eric I found it I bought it at I think it was AutoZone. But I fixed it it was working for like 2 weeks and then all of a sudden it went back into limp mode. Now I went and changed the speed sensor before that it would only go after I went back and lent mode it would only go into third gear now it goes into fourth gear sometimes fifth and it's erratic now. I don't know if there's another sensor bad but the codes are still coming up p1777 and it's driving me crazy.
@@GodsChampionTazz Oh man, that is shite! I am waiting on my CVT fluid to see how mine turns out. Did you happen to visually inspect the related wiring harness and connectors? Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. If not that, you can spend countless hours researching....or countless $$$ getting it fixed at a shop. Let us know what you find and good luck!
@@Eric-hk5xt Yeah I'll let you know. Now this was my Father in laws car he gave it to my wife. He had to jimmy up the speed sensor harness because some of the wire looked frayed. I don't know if it could be that or not , and still throwing out that P1777 code. But I'm going to look at it and make sure it's ok.
@@edwinalexander1170 that leads me to further believe that the flow control valve in the pump is going out and leaking and not allowing the pump to work to its full potential.
@@edwinalexander1170 unfortunately you either keep driving it till it keeps getting worse and eventually goes out, or look into getting the transmission rebuilt or replaced now. If you are mechanically inclined or like a challenge, you can tear out the tranny and rebuild it yourself. There are a lot of videos available showing how to do so.
What is the symptoms of a bad step motor? Reason for asking I got a code for P1778 I changed the stepper motor vehicle changes smooth sometimes, at some point on acceleration vehicle revs high to 40km then lurched and start driving normal happens more often each time I come to a full stop
