They might goodwill warranty the transmission problem, if there is one. Many here have had their warranties run out, only to have Acura good will warranty them, or work out a deal where you are not burdened with the entire cost (i.e. 50/50, etc).

King of Pain

Thanks for the advise ankur.

Well, drove it a little more today. The light didn't come on. Pushed it a little and no problems. I'm going to replace the sensors and hopefully aviod any transmission problems. If that doesn't solve the light issue and improve my shifting then it's time for a dealer trip.

Majofo

Very true.. but I think the first step is to get that code.. We can help you as far as we can by avoiding the dealership.

I bought my '06 base in Dec of '05 and the transmission was covered to 70K miles.

BigJack75

For the OP or anyone else that can answer, would this help improve shift quality? I have an 07 TLS auto with 47k and it seems to me it shifts hard. I took it to the dealer and they said it was fine. This seems like a pretty easy diy so if it could help I may try it.

Majofo

If you haven't changed your ATF I suggest you do that before the sensors / switches. The 07-08 transmissions were redesigned including the type-s (strong similarities to the 1.5G MDX), so you actually have two 4th gear transmission switches sitting on top of the case meaning you'll need to remove your intake to access them. I changed out the pressure sensors on my MDX and it's not any more difficult but it will take a litte more time. You might have to take the battery out as well but you'll know once you're in there. #12x2 & #13 are the pressure sensors you'll need. I suggest getting new washers as well, but that's a personal choice.

dude this takes 5 minutes and damn it give you CRISP ass shift.....i mean smooooth but crisp....

BTW all 5AT people, change ur AT filter....took me 20-25 mins and the filter is like 15 bucks.....and also i threw in 3 quarts of fluid....and damn the shifting is like silky smooth !!!!

will put together a DIY thread !!!!

^^Spent my Saturday doing the same thing as Swoosh---Drain & Refill, pressure sensor and AT filter replacement. While it took me a bit longer than 5 minutes, I can say that it was not too difficult.
My 06 with ~45K does not show any appreciable difference in shifting, but my peace of mind and satisfaction in doing it myself make a world of difference in my head!

^^^ LOL 5 mins for the transmission sensor.....

the filter took me forever....it wouldnt come out !!!!

but well then used my imagination and got it out and the new one in......did u get the Berk/Arnley filter from RockAuto.....the reason i ask is because that was the only filter i found !!!!

Majofo

fixed.

btw.. on the 07-08 TL (same as 1.5G MDX) the filter location is on the opposite end of the case towards the block and it is nowhere as easy as the 04-06 TL. You have to put the front end up on stands to get it. It's #1 in the illustration below. Get a new o-ring #20 as well if you replace it. The 04-06 TL AT is much easier to work on for these maintenance type of items.. The 07-08 TL will take more time & energy.. at least a good 2-3 hrs with no hang ups to change ATF, sensors, filter.. If you do a 3x3 I suggest getting two filters. drain.. put new filter in.. do the cycle and then before the final ATF fill, put in a new filter.

Hope I didn't miss this info from the thread - but is this the same trans in the 2003-2003 TL typeS Acuras?
Thx

Very similar.. the actual specs on the pressure sensors for 2G 5AT are the same except the body of the sensor is stepped compared to the flat body on the 3G. You could probably use either though.

#12 & #13 + #17(2)...

#12 - 28600-P7W-003

I feel like a broken record..

WRXtranceformed

I just ordered these. My car has been shifting a little slower / sloppier lately so it will give me some peace of mind. I already swapped out the trans fluid about 4k miles ago so I should be fine as far as that goes.

I hate cars

Good luck and let us know how it goes.

Off topic but how did you part with a 500hp WRX? That must've been hard.

WRXtranceformed

Will do. Is there a way you can have the service tech plug in a scan tool and check the voltage of the sensors before you replace them? A friend on my local car club forum recommended it.

Getting rid of the suby was hard, I spent a LOT of time and money on it. It went to a friend of mine though, and he's been taking it to the strip and racing it so I'm glad it went to a good home. I bought my first house and I just wanted to get rid of the extra expense, aside from the fact that with that much power you start breaking more stuff eventually. Plus having a car like that is a catalyst for speeding tickets haha

can someone please tell me the size of the tranny drain bolt !!! ??? I ordered some magnetic drain bolts for my engine and tranny....and the tranny bolt doesnt fit my ride !!! since there is a lot of tranny info here I thought someone could help me out.....thanks !!!!

tweeder82o

NICE, you've all my attention and I've managed to read/skim through all nine pages... and caught on with the paranoia.

anyways, in conclusion, only the 3rd and the 4th sensors are apted to fail slowly? while the other sensors are fine?

and these 2 sensors are enough to promote these positive results and some of you have reported?

maxAmillion

iTrader: (1)

We should see if we could get a group buy on the sensors and filter. I'd be in

WRXtranceformed

So, just got back from the Honda service center. My friend works there as a tech and I made friends with the service advisor. Got my oil changed and had these switches installed, and he went ahead and swapped out my transmission fluid for free.

I was a little skeptical as I usually am on seat of the pants stuff like this, but because my car was shifting harder and sloppier lately I thought I'd go ahead and do it. Wow, this made a huge difference in the driveability. VERY noticeable. I stomped on it after the car was warmed up and I couldn't "feel" the car shift like I could before, it just jumped a gear and smoothly rose back through the RPMs again. No more jerkiness on partial throttle shifting either, just very composed I guess is the word I can think of.

I definitely recommend that anyone with relatively high mileage (I'm almost at 71k on my 07 TL-S) get this done, or if you're having any kind of hesitation or sloppy shifts. Thanks I hate cars for the research and recommendation! I wish this board had a +rep system, I'd rep bomb the hell out of you! haha

I am very interested in changing out the AT filter. I have an 05 RL but the tranny is the same as the 07-08 TL 5AT. I would love to do this but disassembling the tranny just to change the filter is pretty scary. Maybe I am missing something but I have reviewed my 05 RL service manual and have determined the following.

1) All illustrations for the tranny on 05 RL and 07-08 TL 5AT are the same. So I presume they are the same.

2) In my 05 service manual, the only place changing the AT filter is mentioned is in the rebuild transmission section.

3) The filter is an internal type. Note how 07-08 TL illustration does not show the complete tranny it is partly disassembled.

Can you please clarify:

Did you replace a AT filter on a 07-08 TL 5AT without having to remove the transmission and partly disassembling?

If so, could you please identify the external location of the AT Filter? A brief overview of changing the filter would be greatly appreciated.

I did a search on this too and clicked the link in your post it is for models prior to 07-08 which do have an external filter.

BTW enjoy the 3rd gen TL forum. I have learned a lot. Plenty of carry over which applies to an RL too.

^ I was mistaken.. I assumed from the diagram that it was still accessible but it's not..


on a related note.. check out comet's thread about sporadic transmission issues.. it looks like his issues were caused by a clogged filter.

stevesrl

Thank's for the reply...It is what I expected. I will check out the thread you mentioned.

I have the torque converter shudder issue (low rpms 4th and 5th torque converter does not unlock).

I read plenty about it but have not come up with a definitive reason or solution. I plan on changing all the electrical sensors that are associated with the torque converter lock up and including all 3 pressure sensors.

Dan1629

I was under my car yesterday(07 type-s) could not find the filter location. Is my trans different? did learn a trick though. if you drop the fluid while the car is level 3qts come out. next jack the car up at the drivers front jack point jack it up till the wheel leaves the ground and another qt of fluid dumps out instead of a 3x3 I did a 4x2

saltysteve

would this fix the problem my 04 has with shifting?
sometimes it doesnt want to shift or feels like its going back and forth in between gears- feels wierd and car starts to shake. i take gas off and press gas again and it goes away.

would it cure this issue?

Majofo

The 07-08 AT filter is inside the bell so it has to be dropped to replace the filter. btw.. some have reported draining 4 qts on level ground. Make sure your ATF level is correct when you put 4 qts. You're not getting as much ATF circulated with a 2x2 (the 3 doesn't stand for 3 qts.. it means 3 drains - 3 fills). You might still want to do a 3x3 with your method if indeed another qt came out of the sump since it'll increase the percentage of fresh ATF.. btw.. don't you mean lift the passenger side up?

Dan1629

I jacked it up on the drivers side, dont know if passenger side works also.

What happened was I jacked the car up to take the plastic plate off get stuff under there like the drain bucket bla bla bla, anyway I took the plug out and lowered the car back down. waited like a half hour. when I looked under there was no fluid coming out so I jacked the car back up to put it back together and i heard it splashing into the drain bucket. looked under it was pouring out let it drain another half hour took the fluid poured it into a gallon container wich it filled put in 3 qts drove around the block checked stick yep needed another qt. added it drove it for like a half mile went back and did it all again.

i have a 05 tl 5at did a drain and refill about a month ago tranny feels great but still takes a little longer to go in gear like reverse but while driving there is no hard shifts any sugestion should i chnge the filter and rings my car has officialy now 100.xxx miles if youre in bk/qnz/or li and you have done this before and know how to would be willing to swing by to give a test ride to explain better

I think this is interesting. For the most of latest Acura/Honda models, I found there are following 3 pairs of part numbers for these pressure switch parts. And the price is quite different also. See the following,


2010 RL and Honda Ody, Ridgeline, Pilot...
28600-R97-003 $8.40
28610-R97-003 $8.40

2010 TL
28600-R36-004 $26.29
28610-R36-004 $26.29

2009 MDX and many of pre-2009 models....
28600-RAY-003 (TEXAS INSTRUMENTS) $32.56
28610-RAY-003 (TEXAS INSTRUMENTS) $32.56

The pressure switches for 2010 RL are only 8.4 bucks, while the 2009 MDX the typical TI ones are at 32.56.

Ok! why in the world does that most expensive flag ship latest 2010 RL get 8.4 bucks one? Why? What is so good about TI parts? gold-plated or something?

As far as I examined the tranny diagram of 2010 RL and 2009 MDX, those look 99% same, yet, those pressure switches seem totally different at least part-price wise.

If the "origin" of tranny issue lies on this poorly des--, whops, deteriorating pressure switch part itself, shouldn't the pressure switch be fully redesigned with more robustness/longivity? why it gets cheaper? ok, cheaper does not always mean worse, but when it differs like 8.4 vs 32.5 bucks... welll... there got to be something better in 32.5 bucks one.... and worse in 8.4 bucks one.....

Then, does it mean the owners of later model year honda/acura which has cheaper version of pressure switch must replace these pressure switch at more higher frequency? confused

I remember reading in one of your many posts the ATF that you recommended. I'm planning on doing the sensor replacement and ATF drain/fill, but can't remember what fluid you recommended. My TL is at about 75k on the original tranny fluid.....yeah, I know....long overdue. Thanks to this thread that will not be the case anymore. Thanks for this sensor find! I'm interested to see what it does for me.

Did a tranny flush and changed out the filter today. Not to hard , woulda been lil easier if i let the car cool a bit more than i did. Lol, love a lil burn when u touch stuff. Any who car shifts really smooth and goes threw the gears with no effort.

It should be said i did a flush and switch change around 82,000 miles. Helped alot there. Im at 102,000 and goin as of today.

For some reason this thread got deleted from my subscriptions.

I use the Amsoil ATD. But as I've said, it's not on the approved list for Hondas. I just liked the additive package and it's a very heavy duty fluid. It's been in there for well over 50,000 miles.

There's also Redline D4, an excellent fluid. I've never used it in the TL but it worked very well for the super high trans temps in my GN. I may get bored when it hits 100,000 miles and swap out the Amsoil for Redline but only due to boredom.

05TLRIDER

Thanks for the info. I just ordered some D4 from their site, because as it turns out there don't seem to be any local distributors for me.....well at least none that carry D4. Hopefully I can get it this weekend sometime so I can do the other stuff all at once.

Hello guys,

I think I am getting some shimmering simptoms although its hard for me to tell due to the streets in PR being soooooooo bad. I probably noticed it a couple weeks ago. and I occasionally feel it. my TLIs Auto 2004 and has 59k miles on it. How can I tell if I have permanent damage or if it can be fixedwith the sensor replacement and a 3x3 ATF change? Already got the ATF in my house and already ordered the 3rd and 4th sensors, I will do this as soon as I get the parts in. probably about a week from today.

Any sugstions?

Peace.

Rolan

I hate cars

I would do the sensors first just so you know they fixed it. Then do the 3x3. It's tempting when the sensors fix it to not do the trans fluid swap but just remember the shudder beats the fluid up badly so it is necessary.

If it's still shuddering and not straight out slipping, chances are it can still be fixed with the fluid and sensors. However, there's going to be some accelerated wear.

Going to change the filter and fluid with Amsoil and planning on changing the sensors at 100k along with the timing belt, water pump, etc... Lets see if this makes the shifts smoother.
