- Weber State University (WSU) - Automotive Technology Department - Transmission Lab. This episode covers the Honda AT5 5-Speed Automatic Transaxle which is used in many 2001-2014 Honda and Acura vehicles. This is an automatically shifted manual transaxle.
Unlike regular automatic transmissions, automated manual transmissions (AMT) are manual transmissions that are controlled by a Transmission Control Module (TCM) computer. To the driver of the vehicle, these transmissions operate like an automatic transmission.
Questions for teachers:
1. List the major components of the Honda AT5 transaxle
2. Does this transaxle use planetary gear sets?
3. Does this transaxle use a valve body?
4. Does this transaxle use a torque converter?
5. Describe How this transmission shifts gears
6. Where are the electronic components located on this transaxle
7. What are some advantages of the Honda transaxle design?
8. What are some disadvantages of the Honda transaxle design?
9. What is a common failure with this transaxle?
10. Tell me one thing you learned or found interesting in this video.

I read that Honda developed an automatic transmission with standard helical gearsets back in the 1960s in order to circumvent patents from Chrysler and BorgWarner on automatic planetary gear transmissions. They were also the first to develop a clutch pressure control system using a reaction arm on the torque converter. Honda also had a manual transmission which was hydraulically shifted in the first Civic.
+douro20 Great information, thanks for the feedback! They still use the reaction arm today.
I've been looking into Honda Pilot transmissions trying to diagnose a problem with mine. This is video is by far the most outstanding in explaining their operation! Well done, and Thank you!
Cannot thank you enough for this straightforward explanation of how a Honda 5-speed automatic transmission works.
This amazes me as an engineering student because this is what I want to do after graduation. Thank for very thorough explanations. Love your videos.
DRIFTWORKXX Thank you!
Excellent video, clearly explains the Honda AT5 operation far better than the factory shop manual. Thanks for creating and posting!
Thank you!
Excellent video. I have a 2005 MDX MDKA 5spd Transmission (212,000 miles) with a slipping Sprag (1st Hold Clutch). Known problem for loosing forward power after a stop. I overhauled the transmission (170,000 mile) but did not change the Sprag, it seemed ok on my bench test. Now I regret not changing while I had it apart. Honda does not sell the Sprag alone, but the whole assembly ($300). I wish someone whispered that secret back in time.
Absolutely the most comprehensive explanation of that type of transmission on the internet. Even though you're not dynamic in explaining, you are a master of keeping my interest. Not only did you earn another subscriber, you definitely gained an admirer of your knowledge and way of sharing it. I can't say enough about how much I enjoyed every second of your video. Bravo Mr. Weber Auto, Bravo!!!😎☝👍
This is very interesting! Honestly almost seems easier than a typical planetary set. All the gears are there to look at. But, no double duty so physically taking up more room.
Well done sir!
Thank you for making this very informative video. I also like the solenoids being mounted externally. I have been chasing transmission problems in my bro-in-laws 2000 Accord and cleaned the solenoid screens in an attempt to "fix" his transmission. I now understand they must have been clogged with friction material and the transmission is on it's last leg. Thanks to your video I do admire the design. I just wish the friction material was tougher.
Thank you!
Thank you for making this video, it was very helpful and educational for me repairing my Honda transmission
Thank you, I am glad it was helpful
Thanks so much for taking all the time you have to make this video. I live in the UK and have a USDM Civic and the transmission is fine for the moment but this information is very handy because if anything went wrong i don't think anyone would understand it. I have to change the timing belt myself because I don't trust mechanics to understand that the engine is running in reverse (D16) either.
Thank you!
Thanks your Video helped me open up a tans and fix a grinding noise coming from the reverse gear engagement
Fantastic video. There is another TH-cam channel called Automatic Transmission which shows how to disassemble and another video on rebuilding the transmission. This video explains why and how which I really love.
Thank you so much! Awesome explanation! It helps me to troubleshoot my MDX 2002.
Another genial construction from Honda! They make surprise every time. Thank you for video!
Thanks for watching
You rule!!! Awesome video as always. Thank you
This video was unbelievably thorough, thanks.
"I don't work on Honda automatic transmissions very often" - this sounds like a good thing
Amazing design. Thank you for making this video.
AdirondackNY Thank you!
Thanks for your studies and I will like to know about honda mzka 2003 on reverse gear
How its operate,
It Stephen kuria from Kenya 🇰🇪
Really educational videos on this channel, with lots of in depth details.
I film auto stuff on a channel and it helped me understand perfectly how the toyota HSD system works
When you really do your research by the book
🚙😊
That was AWESOME. Thanks for sharing your knowledge.
Great lesson! Very helpful! Wonderful teacher! Priceless Thank you again!
Thank you
Thanks I always wanted to learn about modern drive trains, very interesting
Elizabeth Cherry Thank you!
What a great teacher.
Best video on TH-cam I’ve ever watched
Thank you!
I like how you said unique when this transmission fall just need new fluid I own a 2005 the former owner was tired of this van I just change engene oil and transmission fluid 02 sensors and I have a family van the best video about this van what I seen
excellent teaching video, thank you ...
Thank you!
Excelente explicación,muchas gracias.
very interesting explanation.go ahead and do so for overhauling
Thank you!
thanks for this...
Very good information, well explained and easy to follow. You pointed out that spring for 3rd gear clutch, how it forces the pressures unevenly, makes sense. I would add, the spring could have been made better, allowing evenly applied pressure, on top the fact that shaft has more work to do connecting the other two shafts together, probably adds to the premature failure of that clutch... and they could have made the clutches larger in diameter for better hold?
Very informative, great
Thank you!
This his guy is awesome. Thank you so much for this information .I have questions on adjustment of the linear Solinoids for honda transmissions .If you ever have the time I would love to see what you would have to say and demonstrate. Thanks
what an excellent job
Thank you verry much professor!
Thank you!
Very well explained
ขอบคุณครับอาจารย์ครับ
Great explanation!
Thank you
Excellent video, I appreciate your in depth explanations. I have a 2011 Odyssey with a 5 speed transaxle. When I let off the gas there is a surge or jolt felt when the transmission is downshifting. It seems to do it regardless of what gear it is coming out of. What would you say is the reason for this? I am thinking it is solenoid related, but not sure which ones or if it is all of them, or perhaps a filter problem.
Very good.
Thanks for the AT5 training video. Very good. I have the AT6 behind a J35Y1 and it is brilliant.
I also have a 1997 VTI-R H22A4 with a 4AT Sport Shift. I believe these are vulnerable and fail often. Possibly due to poor OEM parts, or so I am reading, such as clutch Fibre, and solenoids clogging, etc. Even with schedule service.
Would you have any experience you could share on this box?
Thanks.
The video is very helpful as a reference material. whether the Japanese version of the Honda Odyssey 2006 atf transmission is also like this..??
Thanks
Very interesting to learn about all the sensors on this transmission, I was wondering about the shifting logic because if the ecu detects no vehicle movement and throttle past a certain %, it will upshift from 1st to 2nd even if 1 is manually selected, I've found this very frustrating when launching and going up steep hills.
Yes, it does that to prevent engine damage. Thanks for watching
J Kelly u r the best!!!
Master!!!
Thank you!
The purpose of the shift fork? Thanks for the video; my 2008 Honda Odyssey transmission … when I shift to neutral, there’s a grinding sound and then the engine wants to die; also, when shifted into park, the van will still roll. So this video helps out a lot.
325,768 miles on van, brought van used with 90,000 miles
You are awesome!
Thank you!
Thank you sir
Hey I have a silly question, what does it mean if there is fluid in the internal clutch of my 1998 Honda Odyssey?
That 1st gear "sprag" is the 700R4/4L60 sprag, as well. (Install the correct way, too), it helps.
Great video, my family has an odyssey with this transmission. Any chance you will review Honda's new 10 speed automatic?
Yes, just as soon as I can obtain one. Thank you!
I have a question about what holds the transmission in park is it a gear or a pin my 2014 honda crv won't hold its self in park. How can I fix it. You are the man I need to ask because ya do a great job explaining how that transmission works
This transmission has had a lot of issues over the years in its V6 application. The 6sp replacement seems to be a lot better. Honda's new 10sp is their first planetary auto.
Very true. I hope their 10 speed is a success. Thanks for your feedback!
Not true. These transmissions regularly last 200K miles if maintained properly. More importantly, these units shift very efficiently and don't gear hunt. The new 6 speeds lock up the torque converter in much lower gears and have a dead pedal feel. The AT5 is far superior to the AT6 from a driveability standpoint.
I have a 5AT in my 09 TL im looking to supercharge my engine to make around 350-400whp do you think the tranny can handle that amount of power?
@@scottn7694 I second that. I have a civic(2012 w/ 1.8) that survived not being serviced for over 60k miles and, still drove great with mystery very dark atf (didn't even smell like atf anymore)
My guess as to why you found the 3rd clutch piston crooked is excessive piston travel due to the wear of the clutches/steels. The design of the spring caused the piston to not return to the bore squarely.
Yes, I agree. Thanks for the feedback!
I can only imagine how complicated/complex the newer 10AT’s are!!!!
This seems to be the same concept as was used by GM/Saturn in their TAAT 4 speed automatic transaxle of the Saturn S series. They have an input shaft and a counter rotating shaft geared to the final drive differential and a hydraulically operated slide gear for reverse.
squagimus Good observation, Saturn did use some Honda transmissions in some vehicles. Thanks for watching.
Mr Kelly do you know if MJFA and BJFA transmissions mounted on 2006-2008 Honda Ridgeline are interchangeable? Best wishes!
Very helpful and so accurate explanations of transaxle, i would like to say thank you for your time and effort to explain this functions, very hard to find like you specialist who is really good on his job thanks a lot. I have a Kia Spectra 2004 model and its total milage is 87007km, Auto Transmission. When im going to work in the morning i On the Car and i warm it up for 5min and put on Drive mode(D) its stays no respond, does not moves, once i push a gas pedal to increase an rpm to 1.7-1.8*1000rpm, than it will engage and will jerk lil bit, after at traffic light i put to parking(P) and shift to the drive(D) it would engage smoothly and seams nothing wrong would be fine but later on i park the car for 5 hours and start the car and shit to D it would appear the same what it could be i tried to go several workshops they use to tell different things all and im confuse to who beleave if u would not mind to help i would appreciate thanks.
Thank you, it sounds like the fluid in your torque converter is draining out when you park for 5 hours or more. The fluid should stay in the torque converter and is held there by a special valve in the transmission typically called a "converter drain back valve". I do not know what Kia calls it, but I suspect it is leaking. How to fix it? probably replace the valve body or the entire transaxle. Best wishes.
cant i just change a solenoid valve? instead of changing a valve body on the entire tansaxle?
IsmAil Fazilov no, it is not a solenoid. It is a valve.
ok thank your very much
Thank you for your sharing, Professor Kelly. I wish that I can learn from you. I'm a Hyundai motor mechanic in Australia and I overhaul most of Hyundai auto transmission. I'm just following the shop manual but I still can't understand all the components in the gear box.
I just want to know that can you tell it's the valve body issue or gear box internal problems with the oil pressure test when you have erratic gear shifting issue? I can tell the problems with the oil pressure test if one of any gears won't engage at all, but It's hard whenever I have an erratic shift issue unless I dissemble all the internal gear box components. I can't pull the gear box out if it's just valve body issue due to warranty issue.
Also why is the erratic gear shifting(for example delay, shock and jerking) occurring when the valve body has problems? lastly what components in the A/T transmission make the vehicle vibrate? I know the damper clutch is the main cause but can the clutch or brake of the gear box make the vehicle vibrate?
thank you again,
Thank you! I have videos on each of those topics, see my channel at th-cam.com/users/weberauto. Best wishes!
I have a cuestion i hope you can help me.i have 2002 acura mdx 5speed automatic bgha .can i instale a bvha 4 speed trasmission from honda pilot, to my acura mdx ???????.the trasmission case is same same¡
Wow this is so good to knew,
Thanks for watching
Thanks for the video. I couldn't see the gear sizes but I assume effectively each pack has the same torque on it? The small diameter of each pack and no load sharing between packs must contribute to the failure rate of these in the heavier vehicles? The original Hondamatic only had two (manually shifted) gears and reverse. Internally it was very similar. It's as if they just kept adding to the original design.
Thanks for the feedback! Each clutch pack will have a different torque on it. The compensate for that difference with different numbers of clutch plates in each pack.
I have this transmission in my Honda Accord with only 20k miles. Intermittently, the car shifts very rough and abruptly. It is worse when it's cold; it almost always shifts hard when it's cold. Today when I was driving down the highway, it held on to 4th gear for almost 20 seconds before shifting into 5th. What could be causing this? Could a TCM reset help solve this? Are there any solenoids or sensors that are prone to failure, especially in a vehicle that sat for a long time I already replaced the fluid with Honda approved ATF to ensure old fluid was not causing any issues.
Hi Prof, Greetings from Singapore. I have a Honda Accord CL7 5AT (Acura TSX) and I love it. I would like to say that this is by far the most detailed and most educational video on the Honda 5AT. It is both inspirational and fascinating to observe the complexity. The level of insight you provide is priceless.
By the way, I have always known that Honda's auto tranny isn't planetary-gear based - broadly speaking - is there an inherent advantage to Honda's design? And if it's so good - why don't others adopt the same? Likewise, could you share with us about the inherent weaknesses?
Aside from this - could you tell us more about what influences the engine braking effect in an automatic transmission? It seems like my Accord has particular strong engine braking which I like alot and do not observe in other cars with planetary-based gearboxes. Thank you so much.
Honda's design is their design. They do no have to pay patent royalties to use planetary designs. Their design is good, but different. Engine braking is a function of gear ratio and torque converter slip rate control. Some transmissions also use a one-way sprag or roller clutch that free spins when decelerating (no engine braking unless you select a lower gear range).
Great breakdown of the Honda AT5 - really helped me understand why a Honda automatic would be sensitive to heat or ATF problems. The clutch packs seem identical to motorcycle wet clutches (interleaved steel and friction plates). They even look similarly sized!
I just replaced an AT5 in my Ridgeline with a low-mileage used unit (my 3rd clutch is gone - after many miles and a fair amount of abuse). Unfortunately, the replacement transmission seems to have no reverse. Forward gears work, but zero response from reverse.
In studying the factory manual (and watching this vid), the only cause I could see for reverse not working is mechanical (reverse fork not moving the gears). Is there any electronic reason for reverse to not work (I don't see any solenoids associated w/reverse, doesn't seem computer-controlled)?
Thanks!
Thank you! Reverse requires all four shift solenoids and their associated hydraulic passages to be working properly. The 5th clutch, 5th accumulator and reverse servo are all involved. If you get 1st through 5th gears, the solenoids are working and you probably have a reverse servo or linkage issue. Best wishes.
Thank you so much for the quick reply...I was not looking forward to potentially swapping the trans again.
If a solenoid was not functioning, would you expect the trans to throw a code (we have a code reader which can pull trans codes and monitor at runtime).
Its worth having a look at New Holland [or Case] tractor transmissions for a more sophisticated version of this type of transmission. Specifically the NH Range and Power Command transmissions which have a six speed powershift [with auto or manual change as the driver decides] similar in design to the Honda [on a larger scale]. On top of which there is a range box giving three ranges and reverse speeds equal to the second range. The range shifts are robotised synchromesh, as is the forward-reverse shuttle, which require a disconnect of drive while they shift. The robotised synchro changes are similar in operation, though not is design, to that of dual clutch car transmissions such as the VW DSG or the Ford Powershift.
Thanks for your feedback!
Muybien explicado
Not sure if I missed the explanation on how reverse gear is activated.
Thanks for the video!
You mentioned that Honda, other than the others, puts the solenoids directly on the transmission case. Is there an explanation for it? I can imagine that the cost could have been reduced with all the components arranged on one center unit. Can it be that this 5-speed-AT is based on a manual transmission so that the solenoid is built as an add-on solution?
I'm looking forward to you next video.
***** I have no explanation for the external solenoids. You make an interesting point regarding an add-on solution to a manual transmission. Their 4, 5, and 6 speed transmissions all have external solenoids. It is certainly easier to service, with external solenoids. Thank you for watching.
I own an XC90, 2004, which has the Aisin 5-speed geartronic. How similar is this to the Honda Aisin AT5?
When I drive the XC90, it gives me the feel of 'extra gears' between 2 and 3, 3 and 4, 4th and 5th gear. Can you explain what is happening here?
Thanks!
I have a slight whining noise upon deceleration when a let off gas from 35mph down to about 10mph. Same noise even when i put it in neutral in that same scenario. It's a 2006 Acura TSX auto. Please what could be the problem?
May I have the url for dct with torque converter transmission video .
On the Honda at-5 you say the primary first gear does not use a hydraulic clutch but rather a sprag. That the clutch on that gear only engages in manual 1 for engine braking. If any time the secondary shaft turns in the forward direction the sprag bites, then what on earth disengages in park and neutral to stop the transmission of power through that sprag?
There is a replaceable filter on the 5AT? Why did my mechanic not tell me this.
sadly earlier models did NOT have an external filter, and the sump filter gets really clogged up.
Now it make so much sense why I can tow a Honda with an auto behind my RV as compared to "regular" automatic transmissions.
I just rebuilt my 2006 Honda Odyssey. It was overheated. I changed all the seals and clutch pads. There are some issues with the transmission that I can’t figure out. Trouble code P0757 P0776. Start Low RPM have no D gear. The solenoid have been tested and working properly.
I have bought 3 1997 Honda Accords, all with automatic transmission problems. I took them apart and the clutch plates were bad in all of them. So I replaced them with a seal kit and a rebuilt converter, and now I have been drive one with no problems for around 3 years. I guess they had poor clutch plates and the new clutch plates I got were updated to replace the old clutch plates,,,,,,,,,
Thanks for watching
Just learned there’s a replaceable filter. SOB already did fluid change, guess I’ll do it again
Good afternoon any help will be appreciated I got a 04 honda odyssey when shift to reverse it makes a grinding noise but sometimes it does work intermittent but shifts fine in drive any ideas thank you for your time
Reverse is engaged with a shift fork, like a manual transmission. The shift fork is hydraulically activated by the valve body. Make sure your fluid level is correct, check for trouble codes. If the fluid is correct, there is probably an internal problem with the transmission. Best wishes.
Thank you for the video, very informative and very detailed. I do have a question though. I have an 04 Acura TSX. Is there any way to modify the transmission to handle let's say more than 300hp? Like the old American transmissions for example the THM 350, 400, 200R4, 700R4, and 4L60E all have shift kits from various companies like B&M that add extra clutches to the clutch packs to be able to handle more power. Is there anything similar for this transmission or can you just add extra clutches to the clutch packs in the honda transmission?
I am not aware of a way to do that. The Acura versions of transmissions are typically stronger than their Honda counterparts
@@WeberAuto Thank you. Again amazing video, thank you so much for your time.
Great video, thank you! Is that transmission different to the MCTA found in Acura TSX 2004-2008 4cyl.? Thank you
That's what I'm wondering? Which Honda transmission is that one? Nice to see most of them are built in a similar manner though
@@rickybobby8563 it’s an 03 odyssey, which is nearly identical to any 3 shaft 5 speed on a 6 cyl Honda/Acura. I’m not sure about the 4 cyl models however
how much power do you think one of these could hold?
What type of transmission fits the JDMF23A Japanese engine
So all and all is it a reliable transmission, I have a 2013 after it hit 50,000 miles I changed the oil ran it for a week change the oil again ran it for a week change the oil again this way I can get all the oil out of the converter which you really don’t you get about 80%, then When it hit 90,000 miles I just dropped 3 quarts and added and they say to do it every 50,000 but I do it every 20 it’s too simple not to. I don’t beat the car at all I’m 60 years old I’m trying to figure out by taking care of this vehicle what the longevity should be, I live on Long Island which is a mixed driving highway and around town but it’s not city driving like Manhattan that’s for sure anyway any positive input on my transmission would make me sleep better . thank you
Q: Can you swap the AT5 in place of the (infamous) BX7A..?
Hello Sir
Question:
2009 Honda MDX
66174 FAULTY TRANSMISSION 3RD CLUTCH FLUID PRESSURE SWITCH-
P0847 OBD-II Trouble Code:
Transmission Fluid Pressure
Sensor/Switch “B” Circuit Low
Before this issue above there was a software update applied for a shuttering torque converter...few years later the DTC-P0847 issue diagnosed to be the switch being as the issue and replaced but my question is -
Do you think there is internal damage that occurred internally over the course of these issues due to this switch failing and and the seemingly simple fix/issue being the software update/switch itself? Im concerned about gradual issues with the transmission and longevity.
Looking to purchase this vehicle and has currently 130K...
Hi Mr. Weberauto, you said the reason the 3rd clutch pack wore out prematurely is because the return spring is crooked making the Piston crooked causing uneven apply to the clutch discs. My transaxle is doing this and this is a common failure of this transaxle. How can we fix it? My thought is the spring must be redesigned so the top and bottom is flat but who would even be able to do that? A machine shop? Maybe a welder can weld supports on the spring top and bottom so it sits flat?
I think there is a new spring and clutch housing design to address that issue.
@@WeberAuto thank you Mr. Weberauto. I have pulled out the transmission and will be checking the parts soon to see if it has the same abnormal wear on it and I'll see if the parts being sold are the new design. Thank you again
Does anyone know the maximum torque the gearbox can withstand?
quick question too, if you put a normal auto into neutral you can rev the engine as much as you like and the vehicle remains stationary. In the Honda auto there is a rev limiter for neutral but if you defeat the limiter by putting the trans in N whilst moving the neutral gear actually provides forward motion at high rpm. how come?
There is a slight drag created by the fluid in the clutch packs. It is normal.
Thankyou!
Hi..., how can you tell slipping Symptoms? Reason being I just got mine redone. But it tries to keep going with a small jolt. When I apply the brakes slowly. Or when I press the accelerator slowly and ease off. The rebuilder keeps saying mine is fine. Plus I hear a very large click sometimes. When I put it in reverse also. The motor mounts and tranny mount are all new...thxs
If the transmission slips, the engine rpm would increase as you accelerate, but the vehicle would not speed up. Best wishes!
Hi ,Honda it used Z1 transmission fluid before 2011 and it was switched to Dw1 later and it is thinner than the Z1 , i have accord 2014 4-cylinder k24w2 engine the Middle East version comes 5-speed transmission What is the fluid for this transmission Use under high temperatures in the Middle East, Like honda z1 , amsoil fluid atf Multi-Vehicle or Fuel-Efficient fluid like dw1 thank you sir
I have a power vibration from 1500-1900 on first and, second that happens when changing gears and, is very present at 1800 rpm. Otherwise works great. This is a civic 1.8 2012 at5 thanks.
Hello and greeting from Romania. Interesting video about Hondas transmission. I want to buy an Honda Accord 4 cylinders with an automatic transmission (2005 2007 7 gen european model) and i was wondering if it s a safe bet . it is a reliable transmission (as long as it is mantained) or i am better with a manual one?You said i had some revisions over the years so i hope that from 2005 onwards it got some. i had so far only manual trannys but i like the automatic ones because i drove one and it s more relaxing. Thank you verry much for your videos.
Hello, the 2005 models had some transmission problems. I suspect most of the have been fixed by now, but there is a possibility that you could have trouble. Best wishes!
I don't know much about it, but I'd like to ask. I want to buy a civic 1.8 (5 speed at). Is this gearbox reliable? or if something goes wrong, is it easy to replace?
Which automatic transmission year could replace.2003 honda accord 6 cyl recalled.transmission.that could fit into.it.please reply.thanks May 1 2023
Hello Sir, What is the name of Honda Civic uses trassmission inside the Civic for FD6, FB7 and FC5 models ? Can it be AISIN and/or ? FC5 uses CVT but what trade name of company ie AISIN again ?
I do not know who makes Honda transmissions, I think Honda does
Do you know if I can swap my CRV early 4 speed transmission to the later 5 speed transmission?
You cannot swap transmissions, too many differences
Thanks for your reply.
I have a 2010 acura MDX. I dont have any transmission issues or slipping my second gear does shift sort of hard. It has a heavier shift shock relative to the other gears. Is this a bad sign? I was told that honda transmission 2nd gear does shift harder then the others.
Good question. I have not heard of that. Yuo might check with the Acura dealership to see of there is a flash update for the computer which controls the transmission. Besy wishes!
consider servicing the ATF fluid and filter then do a TCM Reset so it relearns proper shift points and pressures with fresh fluids.
Most ppl will tell you "this is normal..." until you need a $50000 rebuild and that is normal course too!
Transmission die of high heat from failed/abused clutches that contaminate valves and plug filters. So drive your tranny gently with a light foot to minimize clutch wear AND service fluid for proper viscosity.
Ultimately tranny fail because skinny clutches are the weak points. Similarly this is like disc brakes.... even gentle driving can not prevent replacement only extend life.
👍
What about how the reverse work
The article of the clutch drum is 3 gears, please write
