No-crank, no-shift: Nissan Altima CVT P1777

The owner left her 2009 Nissan Altima sitting for a few weeks. Then she couldn't get it started...
Oh, and she has to drive it out-of state TONIGHT.
PHAD to the rescue!!
A simple jump-start turns into a fiasco...
Enjoy!

[@somerandomguy3868]

Excellent diagnosis and repair, you know most shops would have made the owner leave it and rake them over the coals when it was finished, great job 👍

[@tylough]

Normal shop: Needs new transmission.

[@scuba422123]

that's happened im sure many times!

[@RobertCiampa9112]

Very sad but true + wiring repair, you know the broken wires damaged the transmission. 3 grand please.

[@zoidberg444]

Shit. Isn't that the truth.

[@HollomanUFOLanding]

........and then they simply just replace the wires. $3000 please.

[@rrmech11]

[@Chris-Fennimore]

Yeah, I've been looking for "Shrink-tape" myself. Best I found is the liquid tape. Wow, that transmission ground sure has the green crustys.

[@zoidberg444]

A house call by Dr Ivan. Nice. Bloody rodents. I'll be well prepared for when i eventually do have to work on a Nissan/Renault CVT vehicle after all of this. As for me... Well they can take my 5 speed from my cold dead hands.

I also noticed that the Workshop manual for mums 2010 J32 Maxima does not give wiring colours for circuit diagrams, However, the workshop manual for my 1995 A32 maxima DOES have the wiring colours on its circuit diagrams as letter(s). I have to wonder why they stopped doing it, because its stupid not to in a work shop manual lol. I know ScannerDanner uses Mitchel diagrams which are supposedly quite good.

[@geddon436]

Thanks for sharing these repair videos. I watched your other videos about the nissan CVT teardown. Based on your experience so far, What is your opinion of the Nissan altimas or versas? Would you recommend people buy a altima or versa?

[@SmittySmithsonite]

Damn rodents! I've got a Kawasaki Brute Force atv here with wiring damage (and clogged carburetors). Fixed my dad's Arctic Cat atv last year with extensive rodent damage too. With lawn equipment, I'm always removing nests, or dismembered rodents from cooling ducts and air boxes. They get into everything around here. Got a million of them living in my house too - the cats usually eat them in the middle of the night. Stepped in many a gut pile barefoot ... 😂 Wish I'd get one that I could fix on a visual! Mine always seem super complicated, and take forever to find. Some day, lol. 😁 Nice work on the repair. 👍

[@USUCKER1990]

Hey you gave me hope I have p01777 on my 2008 Altima 2.5s 157k the harness on the valve body got used out cooked fry burn connection from the trans heat temp sensor went out wt a speed sensor and with the step motor and a pop wire to the pressure control so i change it wt a use harness from a use valve body i bought amazon valve body was trash needed tcm retarain so i took it off and transfer the harness to my valve 220 straight trash but i guess amazon scams bc the harness was perfect match but the harness has cracks. 1st gray wire to the tcc lock out solenoid also the pressure switch wire has a crack in the little crack near the bottoms zip lock tie that hold all the wirem have small cracks i guess amazon dont know how to store these things so they go bad or some scammer on line who know but i know i should had return the valve but still i didn't know of the crack i check fuses before.. no blown 10 amps but will double check wt test light now that i saw you do it but def thanks!!!! going to the junkyard to fine and inspect a valve body harness for it should be in better condition then one stored in dryness big thank gotta try well see how it goes ill post a video on my pages tomorrow Thanks!! much respect

[@InsideOfMyOwnMind]

That's racist. I'm offended for the poor rat. We should just let them run free. They were here first. If they are so hungry they have to eat wires that's your fault. We shouldn't be allowed to use anything potentially toxic fixing the wires in case they need to come back. In fact, just give them the car. They deserve it. Make it a sanctuary car.

[@richardcranium5839]

lol that solder will give them cancer in california

[@InsideOfMyOwnMind]

I propose a new tax on motorists in California and New York to pay for food distribution in their neighborhoods since we, the invaders have taken it away from them. And then starting with year model 2020 all cars must contain a minimum percentage of it's parts made from materials that are wholesome for rats to eat, managed and enforced by both the FDA and the ATF banning the possession or use of any weapon of any type that could be used in the commission of a rat murder. Then let them vote in the next election. (I feel so dirty posting this even as sarcasm)

[@Garcansdad]

I bought a '73 Corvette from the original owner who said the passenger side power window hasn't worked in years. Rodents. Upon inspection about 6 inches of the power wire going to the motor was chewed through and in it's place was the rodent nest. Fortunately no rodents were home when I removed the nest.

[@KCautodoctor]

Check out a TS-100 soldering iron that runs off a laptop computer power supply (which in turn can be powered by a inverter off a portable jump-pack or directly off the car battery when you are out in the field or not near a 120V power source). The soldering iron is amazing small yet very powerful & the adjustable temperature control is amazing. I have not needed any of my other soldering irons since picking up my TS-100 a couple months ago. Tons of reviews and demos of the TS-100 on KZbin for you to check out.

[@PineHollowAutoDiagnostics]

Cool! Will have to look that up...

[@sargetester99]

He is right about the iron, good deal, get one.

[@jay7264]

I also mentioned the ts100. I just put alligator clips on mine and use my cordless drill battery to power it. its awesome when doing work in the field

[@topeliteautosale7658]

po1777 stepp motor on the valve body, I just change a transmission with the same issues. bad steppmotor on the valve body. either replace the transmission or replace the valve body

[@AP9311]

Ivan! Great video! Good case study! I'm surprised that in your state that you have rodent problems eating wires! We don't get that in Idaho. Weird! Anyhow, I was going to ask about those Clippers, but I got the answer from someone's comment. Nice little fix! At least it's not gonna be another CVT swap, haha! I just did my tranny swap on my Suburban. Royal pain in the a$&!!! As it's got 4wd system, presents more problems, clearance issues etc. At least I got it done in a day. Haha. Have awesome weekend with Amanda. Take care, bud!

[@PineHollowAutoDiagnostics]

Hey Josh! A transmission swap in one day is always an accomplishment!

[@sabergermd]

Great video start to finish. Clear explanations on how to approach the problem. Working in the dark with a headlamp was admirable,

[@jasharkongjeli1534]

man this is such a great video!! very informative. This is a good start for me because i had the p1777 code, changed out the valve body inside the transmission and now im getting the p1778 code. (im stuck in high gear "ratio") could you do a part two on how to check the rest of the troubleshooting? please and thank you very much!

[@splash5974]

Most likely internal leak. Will need a rebuild or replacement. Did you have any luck with it? Mine has P1778 code also. Was going to order a new valve body but was told the trans is pooched. Mine drives fine till it hits about 45mph or 60kmph and then it wont shift anymore...but below that it runs awesome, no issues. Code only comes back if you push the gas hard and make it rev to about 4K rpm...

[@zx8401ztv]

Excellent repair ivan, you saved the day again :-D I was gifted a butane iron, it was an odd brand but my god didn't it heat the soldering tip quickly lol. With the good old heat shrink i sorted out a wiring hackup, why people make such a mess i don't know, odd people lol.

[@Cheepchipsable]

Already anti-rodent insulating tape. Eric O at SMA uses it.

[@SuperMarioDiagnostics]

Yes more cvt! 👍

[@sargetester99]

Since the wire insulation is now made from vegetable oil, instead of plastic, you will be seeing a lot more of this kind of damage. I see this all week long, many times, more frequent. They took out the plastic because it bad for the earth, but replacing it with varmint food was a brilliant business decision....lol thank you Jesus. ...lol let the money start rolling in for us technicians, finally. ..

[@SuperDd40]

that ground wire on the right seems pretty green to me

[@MrAI831]

I use the Cold Heat soldering Iron. I was skeptical about it but for small automotive wires it works great. Less aggressive than the butane torch. Nice vid, I thought it would be a failed transmission like it did on a Nissan we owned which had a CVT.

[@splash5974]

Other than trans replacement, anybody have a successful repair with code P1778? (also a stepper motor code?) 2012 Nissan Altima Car drives fine till about 45mph, then just wont upshift...code comes on ifyou push the gas and make it rev to about 4K. If you clear code and drive below 60ish mph, it wont trigger the check eng light.

[@fredmalito9869]

I’m four years late to the party, but by 2023 I have learned about Deoxit and liquid electrical tape. I also learned about Hondas split loop designed to repel rodents. Two of these items I’ve learned from Ivan. I think applying all three to this job would have allowed a repair to the chewed wire without cutting and resoldering. With a proper depin tool kit, that wire could’ve easily been removed from the harness and heat shrunk, too. That’s assuming the little mouse didn’t get any of the strands risking future breakage, couldn’t see that from my phone. It’s so easy to armchair quarterback!

[@naqeebrehman9657]

[@shannondewolfe350]

Ivan, I searched on "split shrink tubing" to see if any company has introduced such a product. I did not find it ready made. But I did find a discussion on electronics.stackexchange where one person answering says you can split the shrink tubing lengthwise, wrap the wire, super glue the tubing back together and then shrink it. DISCLAIMER: I have not done this. I have no idea if this works long term or at all for that matter.

[@s31ACE1252]

As soon as you started listing out all the problems and mentioned the car had been sitting, I thought a little critter has been chewing on a harness somewhere. Sure enough....I've had the same thing happen to my wife's Nissan 2006 350Z. It has just over 30K miles on it. Doesn't get driven all that much.....went out one day, fired it up, and the fuel gauge was not working, fuel low light was on.....I thought great, the sending unit is bad. I pulled the access cover to find a chipmunk had been living on top of the fuel tank. It had chewed through the sending unit wires and almost through one of the 12V feed wires for the fuel pump.

[@KSSilenceAU]

In the workshop manuals, Nissan states in the Electric section that if you are leaving the car sitting for a long time without running it or having a charger on it, that you should Pull the "Elec Parts (Bat)" fuse in the fuse box (usually the cabin fuse box), and this will stop any drain on the battery. Stated both in the workshop manual for my 1995 A32 Maxima (Cefiro to you guys) and the workshop manual for my mums 2010 J32 Maxima (J32 Teana to you). Hopefully you find that tip useful for dealing with Nissans that are sitting for long periods of time.

[@throttlebottle5906]

what's a manual? people don't read them, if they did they'd pull the fuse, forget about it and end up with a tow bill anyway ( flashback to Eric-O's video with fuse missing lol)

[@KSSilenceAU]

Simple solution to that, stick the fuse with some tape somewhere were it is clearly visible when getting in it with a note on it as a reminder. If people want to be so lazy they cant even do that. that is their problem and they will only learn the hard way with wallet damages.

[@throttlebottle5906]

Next morning its doing the same problem off again on /off Now tell me what i have to do he said let it go as far its work otherwise i have to put new transmission.. i am so worried its costing a lot to me. Please help me what i have to do .

My 08 Nissan Altima starts lightly shaking at lower speed as if abs is locking up the brakes and then once you get going it’ll stop shaking and seem fine but it feels like the brakes are dragging as if you’re trying to drive with the emergency brakes on. What could be causing this? I’ve been told it might be the cvt transmission.

You should have checked how many miles it's been since p1777. If lots of miles, customer ignored mil light.

[@hooptierescue2540]

@Pine Hollow Auto Diagnostics they make an excellent silicone tape these days that actually tightens up around the wires as it ages which is almost like heat shrink tube but without having to cut the wire to feed it over. You can buy it in hardware stores for repairing garden hoses.
