2015 Honda Civic Touring CVT Was driving along on cruise on the highway suddenly the engine started to REV really high then I was getting multiple errors on the screen: Check VSA Check Emission Check Hill Start Assist Turned vehicle off then back on and tried to accelerate and same issue with the revving, didn’t seem like it would shift. Then finally got a “Check Transmission” local mechanic pulled error code p0793 / intermediate shaft speed sensor. I recently had the transmission Fluid and oil changed by the same mechanic as well as the tires by another one about a week ago. Transmission fluid was purchased directly from Honda. I am passed the warranty for the transmission as I’ve exceeded the mileage so I’m really hoping it’s not the transmission. Any thoughts? |
Re: 2015 Honda Civic Touring CVT Yeah but was the correct fluid used? Does it say on your invoice? If the mechanic relies on a parts department person (who has never opened the hood of a car in their life), how does he know they gave him the correct fluid for the trans in your car? You wouldn't believe how many different (and similar) fluids we have to get mixed up....You might expect parts jockeys to know what you need, but many can barely hand out the parts the person at the counter asks for. You got a fault code but NO actual diagnosis? You could throw a new sensor at it and see what happens. Buy it from Honda but don't install it yet. Remove the old one, compare to new. If the tip of the old sensor shows rub marks or damage, that may indicate an internal trans problem. |
Re: 2015 Honda Civic Touring CVT Thanks for your advice.. I dropped it off before the mechanic closed so he was only able to pull the code. Thr HCF-2 transmission fluid from Honda is what I received. Is is it safe to drive 3 miles to the dealer to get them to look at it or should I have it towed ? |
Re: 2015 Honda Civic Touring CVT HCF2 is the correct fluid...... You already drove it to your mechanic.......Driving it more is up to you. Go slow enough it doesn't act super wrong? |
Re: 2015 Honda Civic Touring CVT https://cimg3.ibsrv.net/gimg/www.civ...0d2f5bce48.jpg Pan with debris Yeah it won't shift out of first basically. I drove it there fine. After pulling out the sensor they noticed it was physically damaged. They then dropped the pan and found some metal components in it (see photo attached). They are found bits in filter for the transmission fluid so they will replace that and give it a drive tomorrow to see how it is. They don't know where these metal components came from, hopefully they're not from inside the transmission and hopefully there aren't any further problems with it. |

Those strips look like they used to be part of the cvt drive 'belt' or 'chain', whatever you want to call it. There are a pair of metal bands that hold all the individual links of the belt together (see paragraph below), at least one of those bands in yours has failed and it won't be long until the other one fails too. It WILL leave you stranded when it fails. I just looked in Hondas parts catalog, they do NOT sell the drive belt by itself.....Replace the trans. What's this 'belt', you ask? From https://www.vtec.net/news/news-item?news_item_id=20071 The principles of CVT In simple terms, CVT consists of a drive pulley (input) and a driven pulley (output) connected by a steel belt, which transmit torque from the engine to the final drive. The steel belt is a ring of numerous steel element plates that are joined with two layered ring bundles.One side of each pulley is fixed, while the other side can be hydraulically moved in and out, in effect altering the diameter of each pulley; those changes in pulley diameter are synchronised and as a result the belt rides lower or higher on the walls of each pulley to provide continuously variable changes to the gearing of the car. CVT therefore does not change gear in a series of steps, but instead delivers smooth, seamless performance from standstill to full speed operation. |
Re: 2015 Honda Civic Touring CVT Unfortunately not, I'm over the mileage for the Powertrain warranty. Any idea what caused this? Just strange it happened one week after my fluid change... I bought a Honda specifically because of the reliability :( Is it something where it can be re-built or am I better off replacing?

Re: 2015 Honda Civic Touring CVT Thanks for your help - much more helpful than the Dealer said they don't have a clue what the debris is from. Would there be a part number for the belt / chain? Found this on Ebay: https://www.ebay.ca/itm/CVT-Automati...5YtvNh&vxp=mtr Is there a part number for that belt/chain ? Want to ensure I get the right one if I do get one. |

I just looked in Hondas parts catalog, they do NOT sell the drive belt by itself Looks like a CVT drive belt for something though Are YOU gonna try to install this? I didn't think so. The shop the car is at now, are you gonna have them attempt to install a new drive belt? You may want to think long and hard about that. Even Honda dealers don't rebuild these, A trans specialist should want to strip apart the entire trans to locate and remove all traces of debris from the failure (I guarantee there's more that didn't fall into the pan) and there's a good possibility other items inside suffered physical damage from the drive belt band failing You will probably discover you need gaskets/seals/o-rings and maybe more to do the job. Maybe a new torque converter as well. |
Re: 2015 Honda Civic Touring CVT Sounds good I will take it to a trans specialist. Someone advised to look into recalls for my vehicle and I did find this which sounds a lot like what may have happened: "American Honda Motor Co. is recalling 143,676 2014-'15 Honda Civic and 2015 Honda Fit cars in the U.S. because the software settings that control the continuously variable transmission operation may result in damage to the transmission drive pulley shaft, according to the National Highway Traffic Safety Administration. "If the transmission drive pulley shaft is damaged, it may break, and the vehicle may lose acceleration or the front wheels may lock up while driving, increasing the risk of a crash," said NHTSA in its recall summary. However, when I put my VIN in on the website it says there are no recalls for my vehicle. It is a 2015 Civic with a CVT. " |
Re: 2015 Honda Civic Touring CVT So between rebuild and getting a slightly used replacement you'd recommend the replacement? Got two different opinions from two different Trans Shops...Neither has opened it up yet but one suggested a rebuild (however that is their specialty - they don't do replacements) and the other suggested replacement. Being offered a 6 month warranty on the replacement. |
Re: 2015 Honda Civic Touring CVT However, when I put my VIN in on the website it says there are no recalls for my vehicle. It is a 2015 Civic with a CVT. If the recall search based on your VIN returned no open recalls, then they have all been completed ---at this time. But be aware the manufacturer could issue a recall for something at any time, so check your VIN for recalls somewhat regularly Or if you go to a Honda dealer service department for any work, they are supposed to check your VIN for open recalls every visit The recall you mentioned was to address an issue with one of the pulleys inside the transmission. Your current problem is unrelated to that recall. So between rebuild and getting a slightly used replacement you'd recommend the replacement? Got two different opinions from two different Trans Shops...Neither has opened it up yet but one suggested a rebuild (however that is their specialty - they don't do replacements) and the other suggested replacement. Being offered a 6 month warranty on the replacement. --Local dealership installs a genuine trans --Local trans shop rebuilds the trans you have --Any shop installs a used trans Consider possible problems in the future Consider warranty for each option and what happens if it shoots craps while you are, say, on vacation 3 states away from the trans shop or installer, and you expect them to handle the problem under their warranty Consider your trans shop may not yet realize this is not a typical automatic trans, and personally I would not want my trans rebuild to be their very first guinea pig. (FYI many trans shops won't even rebuild Hondas normal automatic transmissions either) Your rebuilder can't buy the internal parts from Honda, so are they gonna get everything off of ebay? If a used trans is considered, you better hope it's extremely low mileage. (Note: some salvage yards aren't always absolutely truthful about mileage) How many miles did your trans last?? Use that figure as your life expectancy when considering the options.... Another used trans may or may not last any longer than your original unit. .If your original trans lasted 100k, you probably wouldn't want to spend a bunch of money on a used trans that already has 80k on it. A genuine Honda replacement trans installed by your Honda dealer would probably have a 3 year/36,000 mile warranty that will be good at any Honda dealership in the country (ask your local dealer for an estimate and ask about the warranty) Dealers are not rebuilding these CVT transmissions (personally, I'm OK with that) A genuine Honda replacement trans installed by your Honda dealer should come with any internal improvements and updated parts already installed |
Re: 2015 Honda Civic Touring CVT ezone thanks for the nice write-up, it helped a lot i need one suggestion from you which towing truck would you suggest me to buy i have to use for a tow truck near me. |
