3rd and 4th Pressure Switch, WOOOWWWW

[AliGhanizad]

Bought my car with 142k miles on it, and a few weeks after owning it, Blining D light started coming on. I do have the previlage of using a SnapOn Scantool at school. Error= 3rd and 4th pressure switch failure. I never knew how to replace it, I thought they were internal parts.

After a lot of reading etc, I found a tutorial on Acurazine that showed how to do it on a TL. It seemed a bit confusing there but it really is NOT.I ordered the 3rd and 4th Pressure switch from Majestic Honda, almost half the price of what I had to pay at the dealer. And after 2-3weeks (being lazy :P) I finally put it in.


Tools you will need:
22mm Open Socket,
A rag.

Note: Do get new new O-Rings with the switches too.

One switch was under the batter tray. Very easy to access once you remove the tray. The next one was behind the left front wheel, hidden under a black cover. Don't worry you won't mix them up because the have different colors.

First Impression :

WOOOWWWWWWW My car used to kind of jump in almost every gear, especially 1-2 and also 3rd. Now, I can barely feel the 1-2nd-3rd shift. Runs a lot smoother. Next up is a tranny oil change. Its amazing how such a tiny little part can make such a huge difference.

Total Cost : About $60- 65.

Btw if needed , I can give you guys the part numbers too, don't have it on my right now. And I have access to OnDemand5.com website so if the DIY junkies need any repair instructions on any part of the car, Let me know

It's good to hear of some feedback from someone with an Accord. I've read the threads on Acurazine and was fascinated with the findings.

I can't remember ever hearing about an actual diagnostic code being thrown for the failure of these switches. It seems to be the case that they gradual wear out over time, increasing clutch pack wear a significant amount before the ecu ever throws a code.

Even though I do not own an auto, I was considering trading my car in for one.

Good find OP

The shift pressure switches make all the difference on these automatics and I would say anyone with this V6 automatic should change them if you have 80,000 miles or more. It can actually make a difference even before that high of mileage. The parts are so inexpensive online and so easy to replace it really is something that should be done to help keep the transmission lasting longer.

The shift pressure switches have been discussed here on v6performance before in the Transmission Problem thread.

@2 Amigos, thanks buddy. But for a second you made me excited. lol i though I had one more switch to replace and gain more smoothness. haha but it was the gasket
@gwiffer, well mine had been throwing codes for a long time. And these actually do not show up on normal scan tools that check the engine codes. You have to have scan tool that checks the transmission codes too.

@jiga21, thanks buddy. Just trying to help out fellow 7thGen'ers, and also keep the forum active.

@Jaster, ohh ya thanks for pointing that out, I actually was impressed from the feedback on that thread, that really encouraged me to buy them. AND YES, I do recommend everyone to do this. VERY VERY EASY,

@Jaster, bro it talks about Shift Solenoid filter needing to be cleaned. but when I googled it, it didn't show anything for the 7th gen but a lot of results for the 6th gen. Do you have any info on this particular fix?

There are 3 little metal screen pipe filters inside of the linear solenoid block. After you remove the linear solenoid block you will see the 3 pipe filters that can be pulled out and checked for debris. If any debris is found used compressed air or brake cleaner to remove the debris then put it all back together. Do not lose the 3 o-rings that go to the 3 pipe filters. The picture below will help with a visual of their location.

Jasper, are those 3 things you are pointing to in the last photo the actual filters?

Yes, you can just pull them out.

I'm going to give this a shot next time I change my tranny fluid. Hopefully I can find where the switches go.

[2 Amigos]

Thanks Jaster. Will I need a new gasket when I check my shift solenoid filters??

[gwiffer]

Any pics of the pipe filters removed from the solenoid block?

The shift pressure switches are very easy to get to. Raise the drivers front wheel side of the car and remove the wheel. You will then be able to see the shift pressure switches right in front of you. This is such an easy job to do that anyone that has the tools to lift car and remove drivers side wheel can do this job. The 3rd gear shift pressure switch has a black plastic cover over it and will need to be moved out of the way before you can access the switch. I did not have a picture so the picture below is one taken by someone else but I have marked where the shift pressure switch locations are to help with the repair. Do not over tighten the switches when installing the manual states to tighten to 14 lbs-ft. The shift pressure switches are also color coded so it is easy to know which switch goes in which location. The top 4th gear switch is beige/brown in color and the lower 3rd gear switch is black/grey in color.

Thanks for the picture, it does look pretty simple!

[AliGhanizad]

I'm about to do a ATF change in a few minutes. I wanted to know if any of you, especially Jaster, can guide me through the part numbers for ATF (filter) I went to the local stealership, and they gave me that (hahah dumbass) look. lol

Is there any tutorial for it, part number etc for v6. Any help greatly appreciated.

[BLCKFLSH]

I would get #7 (filter) #22 (rubber gasket), #21 (o ring), and two #24 (crush washers).

[AliGhanizad]

hmmm thanks for the post buddy, now i got a question. Is this pretty simply to uninstall/install. And btw, i just did the fluid change, since its in the top part, I don't thing the fluid would leak right? or probably should be like a engine oil filter's leak?

Parts needed that should be replaced:

QTY
1 ----- 25450-RAY-003 Element ATF
2 ----- 94109-12000 WASHER, DRAIN PLUG (12MM)
1 ----- 91301-RAY-004 O-RING (48.5X2.95) (ARAI)
1 ----- 91302-RAY-003 FILTER, GASKET

All of the parts together only cost "about" $26 online.


Here are a couple of links to threads showing pictures and how to change out the filter:

sweettt thanks

[hondav6]

Nice write up ALI. I replaced my 3rd and 4th gear pressure sensors as well about 10K ago on my 03 Accord V6 Auto. They werent bad yet but I did it as preventative maintenance. Very cheap and easy fix and will save lots of money down the road.

[AliGhanizad]

@hondav6, yeah buddy. Even if they are not bad, I recommend replacing them because I read somewhere on the forums , that these are the main culprit for the transmission failure in the v6 trannies, i forgot who wrote that post but he did a good research on um

[Ric]

Good info!

Hi,

I came across some of your post and was amazed how similiar your answers is related to my problem I'm having with my car.

I have a 2003 V6 Honda Accord Coupe, recently purchase and there was no problems. Mileage is just over 70K.

The problem I'm having is the tranny is slipping after 2nd gear. From 1-2 it rolls over fine, from 2-3 is where the problem occurs.

Is this a easy fix such as changing the 3rd gear pressure switch or can it be somee other problem?

Your help will be greatly appreciated.

Thanks

Changing the shift pressure switches is very easy to do and that is where you need to start. The new Honda ATF that is now sold is a lot better than the previous fluid so changing out your ATF would be the next step to see if that fixes your problem. If it does not there are more steps that you can try. Here is an old summary of things you can try that I posted a long time ago. Good Luck

Thanks! I will try and see if that improves the performance. You're very helpful!

[ikethegreat]

This turned out to be a lot easier than I thought it would be. Removing the driver's side wheel allowed for very easy access. The 4th gear switch is the easiest of the two to reach. To get to the 3rd gear switch, you just have to remove two 10mm bolts to move the metal cover out of the way. Can't say I've noticed any difference but if it prolongs the life of the tranny any, I guess it was worth it.

[Scottwax]

Have to put this on my to-do list, along with an upgrade to the new Z1 ATF.

[DreaminAccord]

I just did this today and man was it worth it. I only have 34k miles on the car, but already noticed a difference. The major thing I noticed was now doing 65mph I'm only running at 1700-1800 RPM as opposed to the 2,000 I was before. 2,000-2,100 RPM @ 70mph now. I've already done a 3x drain & fill at 25k so she is shifting extraordinary smooth Thanks Ali for the OP!

[Soopadoopa]

Just as a side note, I'm coming from a 07 TL Type S, and on that vehicle, there were 2 4th gear switches and one 3rd gear switch. That vehicle was also a 5 speed auto, so I assumed it would be the same tranny, but I'll double check to make sure.
