Solenoid Testing & Fluid Flush on Toyota Corolla & Matrix Automatic Transmissions - U340/U341E/U341F
Вставка
- Опубліковано 29 лип 2023
- Today we test shift solenoids and flush automatic transmission fluid on my 2005 AWD Toyota Matrix, but this will be the same for any Corolla/Matrix using the U340/U341E/U341F transmissions. There are a lot of combinations so check this link to see which you have: en.wikipedia.org/wiki/Toyota_...
Solenoid testing should be similar for any electronically controlled transmission that uses shift solenoids.
Fluid flushing should be similar for most conventional (non CVT) automatic transmission. But do your research first, I’m sure there are some oddball exceptions out there.

Best practice when testing solenoids is to test them at operating temperature because they expand and so does the fluid. This expansion can cause the solenoid to not function correctly due to contaminates and damage internally in the solenoid that may not be detectable at lower temps.
Never thought of that, but makes sense, thanks for the comment.
I guess that's why my faulty solenoid works good when cold
Great video...lighting is perfect. Thanks for sharing
Great video very detailed. I like the bucket idea with measurements instead oil catch pen. I appreciate your demonstration of the solenoid functionality. Thanks and sorry for the mess.
Glad the video helped, thanks for the comment.
Nice work! Sub'd immediately after seeing this video for the first time. I hope you do extremely well on your channel!
Thanks for the support, I appreciate it. I have new ideas in the works, just a matter of getting the videos made.
Good video, keep up the good work. Lots of Toyota owners out there. I drive Vibes which is basically a Matrix. Also users like to see involvement / replies to their questions so reply if you can. Wishing you success in your videos.
Thanks for the comment, I appreciate it.
Good job for learning I won’t waste all that fluid, thank you so much
Hey brov, i do really appreciate your very detailed. I am currelty working on a matrix myself as a first timer and your vid has given me a lot more insight on the whereabouts i need to know. Now if its not too much or a request, could you do a vid on mpv mazda gear oil change and solenoid checks as well? or if you know where to point for me, i'd sure will apreciate this. Keep up the good work brov.
That's a good video, thank you for your efforts. You seem to know your stuff. Some good pointers there as well. One help would have been to show where and how you attached the drain hose going to the bucket. That is, other than the schematic showing connection to the radiator. I just did a filter change on my Matrix, '09, and used Maxlife. One curious thing about the transmission behavior is before the transmission downshifts from 4 to 3 I think I can feel the lockup disengage, then a delay, then the downshift. I suspect the software tries to limit downshifts for optimum fuel economy. But when in cruise control that downshift can be quite harsh. I have the fluid level slightly over the fill line and that seems to help. The solenoid you showed that was not removable; can that valve body drop out without removing the transmission? I see there is an oversized lockup control valve kit available for this transmission. I wonder if that's what I'm going to be looking at eventually.
Very good video I have a problem with my U340E trans axle automatic gearbox Not going into reverse I'd like to know which solenoid valve operates reverse.
Thanks so much for the video. Question if second gear hesitates which solenoid should I replace on my Toyota RAV4 2001
How do you replace the solenoid wire on a 2004 Toyota Corolla S , L 1.80 made in Canada?
I like your style boy
Bro, the acoustic guitar was fuxking amazing. Song name?

Which one is solenoid E located? P0770
Fluid looks like it was never changed. How many miles on the matrix? I've changed my Corolla every 30k and added an additional cooler in line to radiator.
270k miles! Who knows what the previous owners did, but given the condition of everything else probably not much.
It’s great to hear you’re doing all the preventative maintenance to can.
@@BrenoAutoGarage yeah. i have an 05 corolla S and the trans fluid was NEVER touched and serviced until about 300k miles. it threw p0741 at me and there is a deep/loudish hum from the transmission now. it still shifts like a dream though? more gas burning and sluggishness, and it hesitates when accelerating. then the code went away. problems didn't though. have no idea what it could be but 2 years later it's still running on whatever went bad. mostly because i have no idea where to start since the code is gone and the deep hum, sluggishness, hesitation and gas mileage issues aren't really affecting me TOO much besides making me worry it's already shot/going to be shot anyway
They say never to flush transmission fluid. What's your view on that
It’s a controversial topic that’s for sure. All the experts say if a tranny fails after a fluid flush/change it was near the end anyways. But plenty of folks think it causes them to fail, either by dislodging sludge which clogs passages, or because the clean fluid doesn’t have all the dirty friction material causing slippage of the worn friction surfaces.
Flush machines at shops push new fluid through under pressure, which seems more likely to dislodge sludge to me. Using the transmission’s own pump like I did seems to be the safest. And keep the old fluid, if it starts to slip afterwards put the old fluid back in, or use a stop slip additive.
@5:30 I guessed Toyota did a po po on this one Matrix (may be AWD), I wonder my FWD's 2009 Corolla LE is the same.
Most of the rebuild kits are listed for both the U341E (FWD) and U341F (AWD), so I bet they are nearly identical internally.
@@BrenoAutoGarage I agreed because why custom made something special for a basic car. Thanks so much for your information and video. 😁
I saw another video you can remove it without completely opening it, leave few set of bolts in place it will hinge
Md muslim Uddin Bangladesh Dhaka good vi
Good Job
my 06 xb is getting a p0741 after replacing tcc solenoid.filter,atf and flushing 3 times it still pop[s up.161,000 mi and well taken care of ...im in a pitfall.
It’s always the worst when the simple solutions don’t work. Hopefully you can drive it a while and get it fixed when the time comes.
