- In this video, I go over the function of the pressure switch, some Hondas can have 2 while late units can have 6. They are always external to the transmission with one wire going to the switch, the one wire will either have 5 or 12 volts with key on engine off. For the most part should be able to change them. Thanks for watching. I do a lot of talking in this video and show the switches at the end.
Thanks you sir, very informative, i was looking for a ohm spec but now i know these switches are just on/off. Just installed a engine and car developed this 843 code. car never had trans issues and seems to shift fine, So i am thinking i may have possibly tugged on the wire when i was disassembling. At least i can check source volts at plug while wiggling things around or see if switch could be stuck in a closed position. Briliant info
To ALL acura honda owners out there this is an essential part if u r experiencing any shifting issues do a drain n fill if that doesnt work change the swiches thank me later.
I changed my 3rd gear pressure switch twice with 2 new honda switchs. And my d light still flashing.. I have that p0848 code. Even changed the harness that to te 3rd gear pressure switch and still flashing.. I haven't had a chance to check the voltage yet.. 04 acura tl.. Do the old switch and new switch have the same voltage?
Hello I have a 2018 pilot elite 9 speed transmission. Getting code 0841 and Honda saying can’t replace switch without getting a new transmission! This isn’t correct is it as I can purchase the switch for 86 dollars. Thank you!
Gary - I have read that a good spray of brake cleaner in the hole of the sensor can fix this 90% of the time. Poor fluid quality whatever might get stuff in it. Tap it on hard surface and dislodge junk. Thoughts or experience with that? BTW excellent video. Thank you!
I would love to hear him address this issue. Thanks for the heads-up on a possible cure but we gotta keep in mind Gary has a business to run and to keep the revenue flowing repair shops need to make money from the mark-up on parts which is usually double their actual cost.
Hondas best engine in the world but transmission sucks
NOT ALWAYS people use n abuse this cars like they never need maintenance if u dont maintain it properly dont blame the car/brand its the owners fault most of the time.
Hi Thanks
What good universal tools or mechain for test shift solenoid and TCM
Thank very much
Are the plugs all the same? Like could someone mistakenly install the wrong plug or will the plug be different to prevent that?
The pressure switches are different colors because they close at different psi. A wrong switch could be installed, the threads are all the same where it goes into the case
@@GaryFerraro thank you, means a lot. 😎👍
2007 Honda Civic. They didn’t tell me code but I just need a new one. Would I be good to drive to Michigan from Ohio , then get it replaced during a week evening?
Good video thanks .. Seems like with the "updates" and color changes it would be hard to confirm you have the correct switch .. Best luck would be the dealer looking it up with the VIN ..I guess ..I worked in dealers ..their not always fool proof either ..Could you do damage if given the wrong switch ? what are the differences ? is it just the pressure that runs the switch ? I worry to much and just want to be sure to get the right one ..Mines grey ...I think I heard you say their black now ..Thanks for any advice you can give me
the difference is the PSI they close at, can't do any damage maybe just a check engine light with a code. Really have to find out what gear it's for if possible, i have shopkey pro so i can see part numbers and what gear it is for
Is it possible to raise main line pressure electricity on these? Have a 2013 acura ilx and you can feel there is a little weakness in the main line pressure. A little bump in pressure could help
what is your engine size
FYI the flashing d light has been going on a vtm light has gone on I normally shut the car off and then restart it and it would go away also check engine light is on
Have the car scanned for codes
Hey garry, i’ve got a 2001 honda CRV that has a flaring issue (2-3 mosty and 3-4 a little) no codes only 02 sensor, also doesnt flare when its cold. What could it be?
the transmission pressure solenoids/switches can do this!
If the meter reads 0, then the switch is bad due to a broken wire. If the meter reads 5 or 12v, then the switch is bad. What if the switch is good? What should the meter read if the switch is good?
if you have a code for a pressure switch, disconnect the wire and make sure you have volts on the wire, if you do, then your pressure switch is bad. If you have no volts on the wire, look for your wiring problem. 99% of the time the switch is the problem
@@GaryFerraro The problem is I'm getting no code, no check engine light, just an occasional flashing "D" on the 2006 Acura TSX with a screen that reads "Check Transmission". The flashing "D" and screen message go away when I restart the engine. I left an Autel AL-319 ODB2 reader plugged in while driving, hoping to catch a transmission code in action, and it still reads no code when the "D" suddenly starts flashing, which happens once every few weeks.
@@niemand000 do you know someone with another scan tool. A code should be stored
@@GaryFerraro Someone on reddit with the same car and same problem was able to use BlueDriver with the engine running and finally capture a code (P0847 for him). He got it repaired.
But user D.I.Y.D. on TH-cam used a Foxwell 614 Elite to capture the "peranent DTCs" on his 2004 Acura TSX:
05-2 A/T Range Switch Short,
15-6 Input Shaft Speed Sensor Intermittent,
26-3 3rd Pressure Switch Circuit Low, and
26-4 3rd Pressure Switch Circuit High.
Despite changing both of the switches (the 2nd and the 3rd), the problem persisted. He finally went to a repair shop, and they diagnosed it to be due to faulty TCM (ECU).
I will be driving around with a BlueDriver to capture a code.
@@niemand000 wow. First time I’m hearing of a bad TCM.
My 05 accords 2 pressure switches have identical connectors, black,brown,grey,white is only difference, very confusing
The connector are the same, the color of the switches is what makes them different, they close at certain PSI, switches also may be updated with a different color, best is to go to the dealer with your vin number
So what is the correct voltage
it is usually five volts
@@GaryFerraro thanks
Sometimes I feel shaky and nervous.
Do you have a code for a bad pressure switch
i have accord 2009 d lamp flashing scanned give me P0848 ( transmission fluid pressure switch B(3rd clutch ) circuit high .) can you give me the number of this part please and picture
The switches are external, what is your engine size? not sure if i can do a picture. Where are you located?
@@GaryFerraro hi , its 2.4 v4
I have a 07 mdx which on dash says check transmission along with code p8048 flashing D light.I have change both switches not oem.Same issue car drive good just the D light and code .Shut the car off its gone until it comes back
is it a pressure switch code?
@@GaryFerraro yes it is but I have changed both switches and it still comes
@@richardlawrence8691 You have to disconnect switch with key on engine off, see if you have either 5 or 12 volts where it plugs into the pressure switch
@@GaryFerraro then what? What result(s) are you expecting? How do you translate the result(s)?
You have voltage... What does that mean?
You do not have voltage... What does that mean?
How much it will cost to replace all the switch
Tajdin Habib depends on how many there are I would only go dealer on that part and they are about 60 to 80 each one
@@GaryFerraro $10 on ebay!
Be careful. Last guy that brought switches from eBay did not work. I would only go OE on those
D light on p0870
Too long, unclear. Others have covered this easier. But thanks for effort.
Absolutely no help at all!
Sorry about that, do you have a Honda with a pressure switch code?
I have the code 848 on 2006 civic . Changed bottom and back top switches . Fluid drain and fill. .still have code and flashing D
Drives and shifts as it should
Thank you Gary Ferraro for the explanation on Honda pressure switches. Thanks for your videos.
Thanks Gary very much enjoying your videos on all the different types of transmissions. Like I’ve said in previous comments my 99 Accord with 60k miles and my 07 odyssey with 70k plus I just like to be aware of what to watch out for. I have scanners and scopes and enjoy mechanics my whole life it’s in my blood but but thank you for sharing 👍 Artie
Thanks Garry last night I put the sensor into some tiolet bowl cleaning and it foam for a while den I use a little to clean down in the sensor hole and try it back and it start working perfect
What did you use to clean down in the sensor hole? Has the sensor continued to function with no problems?
There are only two pressure switches, 3rd & 4th, on my '05 Pilot...Thank God for that after seeing how many they use on the Odyssey....yikes! Would it be too much to ask of Honda to keep the color of the updated switches the same as the originals? This is madness and stupid if you ask me. I've owned Honda's almost my entire married life ('83-present) as I fell in love with my buddy's '82 Accord and I just had to own one when I had the funds to do so. We bought an '85 Civic sedan, traded it in three years later for an '88 Accord LX sedan which we owned for around fourteen years. I currently have a '98 CRV with 301K miles which I drove off the dealer's lot of that year and an '05 Pilot which I bought in '13 with 99K miles under her belt...currently has 231K on it. I mention all of that because like many old-school Honda fans I feel they've lost their way and this pressure switch fiasco is evidence of it. Great video, BTW...thanks.
Thanks for sharing Gary! Keep up the great work!
Thanks for watching
Have a 2004 Acura TL automatic. It has a hard down shift from 3rd to 2nd no blinking d or check engine light. Change fluid once a year. Getting ready to change transmission filter. Just wanted to see your thoughts on this . Does it pulling off highway onto off ramp. Thank you. It has 180K miles otherwise does great.
CHANGE UR FILTER AS WELL MANY DOESN'T EVEN KNOW IT HAS 1 CHANGE THAT ADD LUBEGUARD ADDITIVE WITH OE FLUID ALSO WHATEVER GEAR THATS ROUGH CHANGE THAT PRESSURE SWITCH AS WELL RESET UR TCM AND SHOULD NOTICE A POSITIVE CHANGE 😎😎

You say this @ 3:20: The switch is bad if we get either 5 or 12 volts at probe. What should the voltage reading be if the switch is good for a 2006 Acura TSX?
its all the same volts . You disconnect the pressure switch, if you have 5 or 12 volts on the harness side then the switch is bad
@@GaryFerraro Probe the harness side? That would be the connector side. In the video @ 3:20 you say to probe the inside of the switch. So if the switch is good, what reading should we get? Thanks.
@@niemand000right
Hi Gary, I have a 1998 Honda accord with a transmission issue, so when driving and slow down it's like holding back ,feels like its skipping a gear , what would cause that
Can you tell me if any codes are present? Is the car ok cold? Check the fluid level, have the car on level ground and engine off to check fluid level
I want you to tell me what is the reason?
I had to pull the sensor and flash it out an put it back in an it good for a while
it's common for those switches to go bad, i get them from the dealer
I have a p0700 and a p1739 error code for my ‘00 Honda Accord but I do not notice anything wrong when driving. It says I have a 3rd pressure switch failure. I haven’t driven much since the check engine light showed up. I took it to the mechanic about the 3rd pressure switch and he said that he has to replace the whole transmission which I don’t want to spend on
You Do Not need a transmission, it is an external switch on the outside, very easy to fix. Is this a 4 or 6 cly?
@@GaryFerraro It’s a 4 cyl
@@RewindsFeed ok, look at the end cover(may or may not have to lift the car) there is a one wire switch screwed into the end cover. Trans is on left or right side of the car?

Hello Mr Gary I have a 2003 Honda Pilot 3.5 dropped my son to work while at Stop on break a strong jerk happen than my engine shuts off put it back on Park starts like normal when I go to shift to reverse or drive the engine shuts off I don't know what happened or if I can fix it please help me
Hello, for Honda CRV 2008 AWD got the P0842 code, 2nd Clutch Pressure Switch. Unfortunately my dealership only got 3rd Clutch Pressure Switch (Green Color Part No. 28600-RCL-004). I remove the 2nd Clutch Pressure Switch (Grey Color) and install the 3rd Clutch Pressure Switch (Green Color). "D" Light stops blinking and everything is fine, but is there a potential risk? You mention some PSI settings, should I change it again for the proper one (Grey Color Part No. 28600-RCR-004) and remove the installed leaving it as a spare when comes P0847/P0848. Thanks for your Video.
Hi Gary I recently got and 04 odyssey with 130'000mi and changed fluid and is all red now with no codes or blinking lights but it hesitates 1/2 second going into drive and reverse is fine and usually shifts smoothly thru the speeds. Any comments? Terrific video 👍
Sounds like all is ok, can't really do much about that small delay
Low or too much fluid can be the cause.
Hello Gary, I have 04 odyssey with 102k miles, I was driving south in highway doing 70 mph and suddenly D started flashing but no engine light.
I stopped and turn off the engine, checked tranny oil level,no burnt smell. Started the van again and d flashing went away. I’m going to drive back home tomorrow, will odb2 tester come out with a code even if there’s no engine light ? And what’s should I look or check when I get back? Thanks
If the D light was flashing, there is a code present. Scan the car and see what you have
What type ATF will I need to use
either get it from dealer or use a fully synthetic oil
Can you tell me where the 2nd clutch pressure switch is located on the 3.0 V.6 2000 honda accord?
05 Accord baya trans brown/black plugs under thermostat are identical to the ones under starter? In function also??
The solenoids are the same (on/off) but functions are different you have shift A-B-C and a Lock-up solenoid, you can swap them color for color
All my switches and solinoids are good. Surges in 2nd, will not shift to 3rd..
P0752 shift sol a stuck on and P0747 clutch pressure control solinoid stuck on..used trans was from bad wreck. Using rebuilt t. converter
@@user-be9ii9ut4t I would think the used trans is no good. Has different problem than original problem?
I have 03 accord baya transmission with the same codes and will not shift into 3rd, pressure switch stuck on pressure control solenoid stuck on
After unplugging the switch would you check for voltage at the plug or at the switch? The video says to check for it at the switch.
Check for voltage at the harness😊
@@condor5635 How does checking the voltage at the harness (the connector) tell whether the switch itself is bad? And what should be the voltage read if the switch is good?
Was wondering if you had any idea on why my 2004 Acura TL 5 speed auto bangs off the rev limiter right before it shifts it’s like a bop bop bop bop bop shift ab 2 -3 seconds it takes for it to shift. I noticed one of those was a leaking fluid a couple weeks back and then I tightened it and since I did that my car bangs the rev limiter before shifting
Thanks for this vid Sir.. I have 99 accord 4cylinder I get the flashing drive light and wen am driving it neutral up on my and when I take my foot of the gas it goes bk to gear.. witch switch u think I would need to change or check..ohh and one more thing it has a delay and slam in drive and reverse.. I changed the tranny fluid wit mobil 1 ATF transmission fluid..is that ok?
Thanks Gary. Updates and superseded parts, it never ends.
TakaCare,
Bill
Bill K Thanks Bill. You are correct on that.
is Honda circling the drain or what... these simple parts are not rocket science like the machined gears
What cause a pressure switch to stop work
The diaphragm could go bad. but check for your reference volts, Usually 5 volts
Looking at buying a 2011 honda accord with right at 100K miles on it. The owner says it is slipping a bit in 3rd gear. Could this be from a pressure switch or something else like torque convertor?
wouldn't be a torque converter, i think the clutch mat be wearing out, does it do this all the time or only hot?
Hi Gary
Quick question I have 2002 Honda accord 2.3l have 3 codes P0730 gear ratio incorrect, P1739 and P1751 also hear some noise when car is idling under where flywheel is.
Are these switches the problem or my transmission is done and needs rebuild.
Please let me know your opinion, had delay once you put in gear and than jump.
As long as this is full of fluid( check fluid level with engine off and on level ground) you have internal problem, pressure switch will not cause this
My 2015crv takes about 10 minutes before moving slowly when shifted to drive position
Have the fluid level checked first, if thats ok then something internal, trans is a CVT
I appreciate the info. I have a 2016 elite 9 speed. It's showing the second clutch A switch is bad. Honda says they don't make the switch and I need a new transmission. I joined the honda forums and they said to message aftermarket zf. I haven't heard back from them. Any information would be greatly appreciated.
i'm not sure have to research. Where are you located?

Thanks for your very detailed and informative videos. I have two Acura's. One 2007 MDX and a 2005 MDX that are showing some of the same symptoms. On both they are not producing any codes and the drivability is good. The issue with the 05 is that when I shift into reverse from park or drive is takes longer than what i think should be normal ( about 2 sec). The 07 has similar issue but when I go from reverse to drive it takes a few seconds to engage as well. Fluid drain and fills have been done very regularly using Honda fluid only. Any advice would be appreciated.
happens both cold and hot? Reverse issues are not common, rarely see reverse issues
Yes, happens both hot and cold ...more pronounced when it's cold. The 07 has done this for many years. @@GaryFerraro
Did you have to drain the transmission before replacing the sensor?
Did you figure it out?
@@ragnar3522 yes thank you
No you do not
Well done! Thanks!
Would it be possible my d4 light is flashing because of the pressure switch connector from the harness ? It was melted to the pressure switch and soon broken off. The d4 light seems to stop flashing once the car is warmed up
yes
@@GaryFerraro I had tested the connector with a voltage meter, but not a mutimeter. It did give light. Does that mean the connector is still good or should I test it with a mutimeter to see if it's really getting enough voltage ?
@@BobiPhettOfficial Test light is good loads the circuit to, but yes use a meter to confirm 5 or maybe 12 volts, Usually 5 volts
@@GaryFerraro what if the voltage is lower than 5 or higher than 12v ?
Can these switches cause shifting problems without throwing a code? What do they do besides tell the computer the pack is full. Do they calculate wear like the Chrysler?Thanks
They just tell computer what gear the trans is in, sometimes may cause bit of a long shift (i have seen that a few times) most of the time causes a code with the check engine light on
Gary, 03 honda acura mdx P0873, the name of the switch is "transmission clutch pressure switch " ? Is no the same like a transmission oil pressure sw right?
It is the same
Hey quick question inside transmission dont have neutral what u think problem
In Neutral what happens? does it move forward in neutral?
You go by the psi if you don't know the color
Thank You… this was informative…
So these pressure switches would throw a code when bad or there are cases where bad switch isn't triggering the code? Basically would like to know when these need to be replaced or what are the symptoms? Thanks!
symptoms would be a flashing D light or check engine light, may not feel driveability problems. Most of the time the switch is the problem, a few times when it was a wiring issue, i found the car was in an accident
Years ago, I had one giving me issues on my 07 Honda Fit without a code. I had a slight issue with hard shifting from one gear to another and another issue I couldn't find the source of (it might have been a hesitation? I don't remember anymore). I had taken to a Fit enthusiast group online and someone suggested one of the pressure switches. I had tried everything else so I figured I might as well and it fixed the problem I was chasing plus the hard shift. It was the lowest plug on my transmission and my splash shield was long gone so I think it was just water that had damaged it but it improved my gas mileage in addition to fixing the other issues. No idea why I never got a code for it.
Any chance a po747 or p0767 can be a pressure switch
No, These are mechanical codes thats points to something internal, Trans is full of fluid? Honda's get the fluid checked with engine off
I have 12v across the pressure switch instead of 5v. What does that mean? I've swapped 5 different switches and still have same codes thrown and my tranny is shifting crazy. I also have codes for 4th pressure switch. I'm really confused. I need help.
it can either be 12 or 5 volts, are you changing the correct switch
@@GaryFerraro very sure I'm changing the correct switch. I guess I'm on my way to a new transmission. But I still don't understand why I have 12v instead of 5v stated by Honda. I just hope my ECU is in order.
did you compare to another switch@@lastof4brothers

Hi Gary, can you pls help me on this. I have a 2012 AWD CR-V. After replacing transmission repair kit I still have a down shift delay specially to 2 nd. Or I feel it as wrongly recognising the required gear for that particular instance of the vehicle movement.
The repair manual gives just one part number for both pressure switches. But two switches has two different colours. Can i match the size and thread to replace an after market switch or should I always match a colour. Pls note there are no MIL codes but just delay in downshift on mild acceleration for nearly 6 months.
They could be the right part just different manufacturers use different colors
the pressure sensors use color to code the pressures

Thanks for the vid Gary. I have an 2008 Fit that I let my daughter take. Now it has problems. I think her husband replaced the drivers side half shaft and filled the transmission with cheap fluid and it was overfilled. Would that cause these trouble codes- p1780 p0767 p0762 p0757 p1747? I drained a little over a quart and filled with Lucas trans. fix. and the grinding that you could hear when idling in park is barely audible now but the codes remain. Am I correct in assuming the wrong transmission fluid was used?
So you cleared the codes and they came back? or you did not clear the codes. Fluid wouldn't really cause that. Why change the axle?
@@GaryFerraro Cleared and came back, ya good question. My guess is part of the plastic that covers part of the undercarriage and the right wheel well came off and was making a loud noise so that means replace the axel? Plus there's a recall on that part. I'd laugh with you but it might hurt. She's not talking to me so I don't know much. All the information I've researched says you must use Honda AT fluid or at the very least Dex VI full syn or it causes damage. Is this not the case? It's been driven 3000 miles in her care and has a total of 70,000 miles now, still a baby.
@@GaryFerraro Thank you so much for your help! Unfortunately I think I'll junk it. What I saw after taking a good look at it tonight horrified me. Both spindle nuts were barley on so I'm sure both half shafts were just spinning inside the tranny grinding it all up.

Gary thank you for the video. I am here because I'm having a delay between third and fourth gear. Shift basically feels like it's slipping . it'll catch good would this be a Pressure. Switch. Again thank you for the video
it's possible, could be internal problem too. do you have a scan tool to view data?
@Gary Ferraro yes when my wife gets home from her road trip I will put the scan tool on it .if there are no codes. I'm guessing it is internal .I did change the trans fluid last year with honda type from the dealer .thank you again.
@@MrSprintcat you could hook up the scan tool and see if the pressure switch is changing from off to on
@Gary Ferraro I'm not sure my scan tool is able to do it. It's a cheap $100.00 autel. It does have a spot in the diag that I can see different values.i did notice the last month or so it would take some what longer to shift from 3rd to 4th.

Does a 1997 Honda Civic EX have the Transmission pressure gauge switches
I believe it may have 2

@@GaryFerraro hay Gary will that make it seam like it’s in Neutral when is it in drive
@@frankieburacker807 Not really, may make it flare on a shift. When do you feel the neutral condition
@@GaryFerraro feel it after the transmission fluid warms up
Very nice explanation on the switches. I have One question that noone seems to be able to answer. I have a 5 speed acura tl. Shifts really nice all the time but I have a delay into drive and into reverse about 4 seconds to engage. Could this be a shift solenoid? I'm guessing there might be blockage in the valvebody or internally somewhere. Been like this for months.
Does this all the time or only hot?
It does it all the time. Cold or hot. It gets a very tiny worse when hot but for the most part it happens all the time. Forgot to mention reverse slams after the delay its not too bad but it does slam.
I have same.problem honda pilot
@@GaryFerraro Is this Hondas sequential box but still using a torque converter but still using a conventional gear system and so is it mostly the sensors that give trouble ? Its just a few yrs. back i remember testing 2006 civic here in the UK which i thought was a full torque converter box and i checked the leval before i test drove it but it skipped a gear at least twice. Is this common fault with them as this car was supposed be low mileage? And then theres the I shift with a straight box system. Which is the most reliable please and or easier to work on. Is there any yr onwards or either you need to avoid. Im thinking of looking around for say 2009 11 model civic thanks
2002 Honda CRV p0845 when I test switch with key on engine off I get no voltage on MM meaning switch is good, right? And this means wiring is bad, or could it be something else?
Ok so just to confirm, you unplugged the harness and checked for voltage with the key on and had no voltage, would either be 5 or 12 volts
@@GaryFerraro
Correct
I ran ground to neg battery cable and probed the inside of switch (3) behind front driver side tire. Key on engine off.
No voltage.
Shifts hard at 2nd and 3rd.
I did go very long w/out atf change and trans fluid was darker than ideal (burnt looking) but I did just change out 3 qts this past Saturday. Plan to do more later but p0845 code came back with test drive. Just trying to rule out switch.
@@wjsteagall If o voltage on the wire with key on engine off, fix that first
@@GaryFerraro
Wait, now I'm confused.
You said in last reply:
"If 0 voltage on the WIRE"
I didn't probe the "wire", I probed the prong inside the switch itself.
Are you saying I need to probe the wire that plugs into the switch, as well?
@@wjsteagall , Did you check this with the pressure switch unplgged from the harness?
I'm also going to change the filter and fluid again and possibly clean the easier solenoids too. 👍
Can not change the filter on this trans
@@GaryFerraro yes you can theres a video on this its a pleated filter on top of tranny
@@tomclose6643 That is the cooler return filter, the main filter you cannot change
No check engine light and no flashing D4 light for me its flare shifting between 1-2 mostly and a little between 2-3!
What is year make and model
Same problem here. 1999 honda accord 2.3. Flares especially on 2/3 shift less on 1/2 shift. Should I replace 2 and 3 pressure switches?
@@martinjay9959 I would go ahead and do both, but mostly the 3rd gear pressure shift will affect 2nd to 3rd gear shifting whereas the 2nd gear pressure switch will affect 1st to 2nd gear shifting. As a test you can unplug your 3rd gear pressure switch and go drive around and you should notice it shifting a lot smoother. Hopefully your wiring harness doesn't break like mine when I unplugged it. I had to order a new wire harness for the 2nd gear pressure switch and will have to cut out the old wire harness and wire in the new one.
@@koreymayo8884 Thank you for that? How long can I drive with the 3rd gear pressure switch disconnected? I was going to pull/check the shift solenoid b&c also. Are the correct parts numbers for #2 pressure switch- 28600-RCL-004 or 28600-P6H-003
and #3 28610-RKE-004? These are the numbers I researched
@@martinjay9959 Well if the transmission has not been overhauled, replacing the switches may not help. so you have a flare on the 1-2 and 2-3?
help acura tsx 04 D flashing and jerks on 1 gear
Have the car scanned, there are codes present, thats why the light is flashing
no codes at all
@@rickxs619 With a D light flashing there has to be a code, thats the reason why it flashes, may need a better scan tool to pull the code
@@GaryFerraro Honda Motors Co. is so 3rd world friendly that the "D" light actually blinks the code itself with morse style pulse... as detailed in the shop manual.
[Some people expect to get a message on the car display pointing to an actualpart number... LOL!].
The trend is part failures never list the cause! (engine oil leaking from old valve cover is actually caused by plugged PCV, not bad gasket 🤫!)
Next well hidden failure screwing with both engine and transmission is... the Serpentine+TENSIONER that is pegged... No belt symptoms but reduced power, random misfires and vibrations. TCM struggles to compute proper shift points! (80KMi and up)

Honda accord 01 mi transmision la velocidad 2rd tarda en entrar solo en tiempo de frio y asta que llega asu temperatura normal se compone, GRACIAS POR SU AYUDA.
Are you having a problem in 2nd gear?
Yes only cold weather
Thank you gary ferraro
@@oscaroscarin ok, what happens, does not shift? stays in first?
In winter time the second gear makes the car slip but when the motor gets hot it goes away
It only does it when I come out my house 1 or 2 times

What happens if I used a lower pressure switch? 1998 accord automatic (swapped out a baxa for a mgpa)has black in the front and green in the bell housing. Can I use the brown where the green is?
Thanks for sharing this information Gary. Have you ever seen a restriction in a Honda shift solenoid screen result in intermittent DTC for one of these PSI switches? I’ve got a 2002 CR-V which will very intermittently flares the tachometer up upon the 2-3 up shift and set a DTC for the 3rd Gear psi switch.
I plan to remove and thoroughly clean the solenoid valve body and neck test actuation. But wanted your opinion as to whether or not the momentary pressure loss occurring at the attempted upshift would set the DTC. Thanks!
If you didn't pull the trans yet, change the pressure switches first
@@GaryFerraro Thanks for your input!
06 Honda pilot when you have a drive light blinking how do you know which sensor switch to change
scan the car to get the code
Michael Johnson,, For your vehicle it is most likely the intake manifold sensor switch. Believe me.
@@michaell3711 This would cause the D light to flash?
@@GaryFerraro ,,, Definitely . I had similar issues with the 90s Accords and never got any transmission codes with a blinking D light. Many are unaware that on those years Hondas,,, the problem is a faulty Air Intake manifold sensor. It is easily located on the 92 to 2002 Hondas.
