3rd Gen Honda Odyssey Transmission Fix 2 of 2 - Filter, Flush, and Pressure Switches

In Part 1, I install a trans cooler and magnefine filter:
• 3rd Gen Honda Odyssey ...
My transmission has been acting up a bit, missing a shift once in a while. I thought I was out a transmission, but after finding a link about replacing some switches and installing a cooler, I think I may have an easier fix than full replacement at 125k miles.
Of course, this is no silver bullet, but it seems to have helped.

I'm helping a buddy out this weekend on his van and this video is money! Thank You for the upload.

[@krashfinatik4396]

Thanks for taking the time to put this video together. You helped confirm my thoughts on (if or not) there was a filter and how to change it.

[@DrJerryrigger]

Thanks for making a video of something that is impossible to see. It give me some confidence that it is actually possible to do.

[@emmanuelcarrion5168]

Thanks for the video. My 2012 Nissan Altima has a similar filter that the dealership doesnt know about. During the weekend when I'm off from work I'm going to attempt to change that filter out of cooler and also add that magnifying external filter in hopes to prolong in the life of the transmission. I also like how Honda and Nissan almost seems to have the same kind of transmission filter housing

Sometimes it may be a software issue. I have a 2010 Acura MDX which I bought used at 200,000km and had a shudder when downshifting at 40k an hour. I did multiply drain and fills and even changed the filter. Did not fix it! I went and got the software updated and now it works perfectly! It's been more than 6 months now and still works great. If a person does the drain and fill every 30 to 50k depending on how you drive, a drain a fill will do just fine and won't need a filter change. My friend who is a Honda mechanic said they don't change the filter, just do drain and fills. I guess if the vehicle has been badly neglected a filter change would be necessary. When I did the filter change, even at 200k it didn't look like it needed to be changed. Hopefully this helps someone.

HI, I just did this trans filter job on my 2006 Ody. Removing the battery, battery box and battery support made the job really do-able. I could easily get to the 3 10mm bolts and the 17mm banjo bolt.

[@SquishyBrained]

Nice. It has been a while since I did it, but I feel like the ABS junk was in the way of that one bolt. That really hurt my hand. I get to do a water pump on the van this Saturday. Boo!

[@CBRRR-eh3ky]

You make me wanna do this. I replaced battery tray when i changed starter so its ready to come out. Did u have to lift ABS a bit to help yourself more?

[@alexsnow8894]

Thank you for 26. Almost lost it!

[@paulvanvalkenburg7815]

What was the long drive issue I have a drive than not drive after so many miles

[@ramonarroyo3471]

I should change the transmission filter if I have never changed the oil

[@isidroesquer5219]

Thank you for the video. I’m having the same issue on my 2010 Honda Odyssey. I didn’t know there was a filter for the transmission. How much money did you spend on the sensor and the transmission filter? Are they OEM?

[@glasser2819]

save your time... only consider OEM parts and fluids. The copies will only cost you more in the long run 👍

[@sarahs7751]

We have a 03 oddyssey right now. Was wondering if its another bad idea to buy a 2005 to 2007 oddyssey or ill be running into transmission problems again? Im hoping itll be ok cause it is very hard to find 8 seat vans and i really like the interior. We are about to have 5 children so we really need a van.

[@jerrydavis3462]

Just for future reference the hollow bolt is called a banjo bolt no biggie ¡!

[@demussmith787]

HI! Thanks for the video very helpful. I am going to do mine I have similar issue. After driving for a long time i have a hard shift How is your transmission now?

[@TheMstwntdLMSV123]

How much of an improvement did you see after changing the filter?

[@CashApp-HelpMeStayAlive]

Next time ..... take off the 3 bolts to the ABS module lines .... Then lift it a little and hold it up with a screw driver . The trans filter right under it will be sooooo much easier to replace. I just did mine .. Make sure to tighten the 3 screws on the filter TIGHT . Also the big screw goig i the middle of filter housing. Otherwise it will leak. After filter change and fluid change , Check for leaks... before putting everything else back on .

[@saeedalsufi545]

After how many miles we should change this filter?

[@CBRRR-eh3ky]

Did you notice any positive change as far as shifting?

[@dangerousfreedom4965]

CAR GAS make a vid

[@jerrellstrawn6409]

A bungee cord holding the ABS manifold up about 1 1/2" - 2" makes a great deal of difference for access. And it's actually the A/T cooler filter.

[@philn1601]

Honda won't recommend to change the filter.

[@gregory891]

I hope you added top oil cooler brackets to avoid vibration induced failure. If you don't, it will happen.

[@SquishyBrained]

I did not, but I was under there the other day and it is super solid. Its not oscillating and its mounted to a solid part.

[@JremV]

SquishyBrained will this work if the odyssey won't shift into second?

i got a 2002 honda odyssy if im driving 60 miles an hour the TCS went on and went up to 3 and check ingine is on also . do you think what is the problem.

[@jesusramos5086]

Who knows were the 3gear pressure switch is located on a Honda odyssey 2004

[@ilahunWaahid]

I got a 2005 EXL (176k miles) last week & it passed inspection. Thereafter, been experiencing intermittent downshifts (D3 light comes on next to D, rpm goes up & speed drops). Do you think an ATF flush with the filter & 3rd+4th gear switch change as shown here can help? No related codes throwing up on scan (I am getting a P0420 for a rear Bank 1 Catalytic Converter, but that is a different issue, I think). Thank you for the videos, they are helping me familiarize with my vehicle.

[@petertirone7078]

I had similar issues with the intermittent downshifts at low speeds/hesitant when cold to upshift...I had gotten lax in changing the fluid (put 30-40K on it since last flush)...Did drain and fill 3X (follow Honda specs/USE honda oil only) and that solved my issue. Going to change my filter this weekend 150K on it.

[@micheledash7269]

Never flush. Just change by gravity even if you do it twice. Worse thing you can do it take old vehicle with lots miles and flush it.

[@jesusramos5086]

Where do you buy the third gear pressure switches

[@SquishyBrained]

I think amazon, if not, rock auto. Use the rock auto search to find the part numbers, it is really good.

[@christyholton]

Dumb question probably, But here goes. I just changed the fluid and now I have a blinking D light the code (P0873) tells me its 4th clutch pressure sensor. I plan to buy 3rd and 4th sensors tomorrow. Any idea how much fluid I will lose changing them out?

[@SquishyBrained]

Christy Holton I don't think when I did mine the fluid was still in it, I think I drained it first. I imagine though you could take out the last threads and get a thumb on it real fast and not lose much at all. As I recall they are pretty accessible. Either way I think you can dipstick it back to the right level, so just grab one quart and hope you don't spill much. I imagine it'll come out like changing the oil though, so you'll have to act quickly.

[@CashApp-HelpMeStayAlive]

Try Catch the oil with a Cup and then put the same oil back in . Or have the new preassure switch ready before u loosen the on on there. That way you can swap them out SUPER fast and avoild more than a tiny bit of oil leak. Im just thinking .

[@dansmith859]

Where could I find the diagram you were using?

[@SquishyBrained]

Dan Smith sorry, not sure where I found that. Probably just Google image search. Try pausing the video in 1080p. If you can't find it I may have it saved somewhere

[@mrjason9382]

Thanks for shareing

[@gregory891]

What results do you have since the work you've done? Long drive issues gone? Do you have any error codes?

[@SquishyBrained]

Sorry, KZbin doesn't notify me on all comments. Errors are all gone. Long drive issues gone. The trans shifts a bit sloppy sometimes still bit does not slip or anything. Seems good. Replaced rear motor mount the other day and it reduced a lot of vibration.

[@CBRRR-eh3ky]

@@SquishyBrained was rear motormount job a pain?

[@glasser2819]

@@CBRRR-eh3ky yes, extremely tight bolts need impact tools or 1/2" sockets + torque rod extension ... ouch all the way 😅

[@shayn1985]

You didn't disconnect your negative battery cable.

[@evanjensen5023]

Why would this be required? All I can think of is so I don't drop a bolt on the positive terminal on the starter, but I don't really see the need otherwise. Can you explain?

[@robbynelson3]

Evan Jensen Its a smart idea from a safety standpoint. Also resetting the ECU might be needed so codes can be cleared and trans can "relearn" or "learn" that new switches were installed?

[@carlwinslow4175]

Would there be a code if a pressure switch was bad?.......I have none showing and would like to rule that out. I have a shudder on light throttle give it gas it goes away I suspect the clutch paks are bad flushed my 05 Ody 4 x times still no luck

[@oilandgaswatch]

Carl - Did you ever figure out what the porblem was? I have a similar issue now.

[@glasser2819]

good news.... the solution may be the top filter replacement! I found my filter at 147kMi smashed on one side. Since I replaced it even the engine runs without misfire vibrations at idle. I am not exactly sure if it was improperly installed at factory or if it's because the glue was falling apart but ONE THING IS CLEAR: THAT FILTER WAS BYPASSED BY OIL FLOW AND USELESS because it was breached. So hurry and change yours with genuine OEM (O-ring etc) around $30.

[@FixItYerself]

is this an '05?

[@SquishyBrained]

OffGridNorthwest nah, 06 I think

[@saeedalsufi545]

After how many miles we should change this filter?

[@glasser2819]

change it around 80kMi but most important is ATF every 40K based on driving conditions
