Ow, ill give it a try as well

Just did this with a help of a friend, while also changing my front disc brake pads. Easy to do with the wheel off. Had a little hassle locating the 3rd gear switch. Once found, it wasn't a problem to change it.

I know it's a late reply but I think the updated part numbers for the pressure switches should be added:

3rd Gear Switch
old#:
28610-ray-003
new#:
28610-ray-013

4th Gear Switch
Old#:
28600-ray-003
new#:
28600-ray-013

Is there a DIY for the 2g or are the switches in the same spots? I have an '03 TL-S with the AV6 swap and I should have done this when I did the swap, but did not...

dcmodels

dumb question I suppose, but is there no 2nd gear switch? only 3rd and 4th? the part numbers given above in post 563, are actually the same as for an 09 RDX trans.

Ed_Zilla

Very Helpful information guys, I just purchased an 08 TL about a week ago and noticed the shaking/vibration from 3rd to 4th. I will be taking my car back into the dealer since I am still covered under warranty.

hi all,
I noticed my Acura (2006 TL 6 cyl with automatic trans) lurching (once each time) while going uphill with cruise control on.
Then my wife felt it lurching while driving I-80 over the Sierra Nevada from Sacramento to Reno. She does NOT use cruise control.
I noticed several posts about the 3rd and 4th gear pressure switches needing replacement.
Does this sound like that pressure switch problem?
The dipstick says there is transmission fluid.
I know it's about time to replace the spark plugs, but it doesn't seem like a spark plug problem to me.
What do you think?
(PS: the weather here has been in the high 90's to low 100's)

hmm seems like something with the grade logic control...not sure though, am just guessing....need to get some transmission guru's in here

Finally had the time to change out the 3rd and 4th pressure switches. Thank you for the DIY! It made the work much easier. Since the car was lifted I might as well change out the transmission fluid.

Gave a test drive and OMG, shifting from 2nd ->3rd->4th was SO smooth. It basically felt I was driving a brand new TL.

chinesestunna

My experience was that I think the new DW1 transmission fluid really made a bigger difference than the switches. The old Z1 fluid was pretty bad and in my opinion contributed partially to all those transmission woes plaguing Honda and Acura for the past 10 years

I'm currently running Redline D4 ATF's in the transmission.

I did my first 1x3 (Redline D4) last week and ordered the switches. One came yesterday and the other should arrive Monday. I ordered the 28600 p7w 003, but I was sent 28600 p7w 013.

It looks the same (brown) as the 003 pictured, but I just wanted to ask here to make sure it's the correct part.

My 04 TL has 77,700 miles and shifts perfectly, just doing preventative maintenance...

Is 28600-P7W-003 = 28600-P7W-013 ???

Thanks!

The technical pressure specs for these switches is taken from the following link. The diagram/ pics of the old/new comparison is *stolen* from someone on this site - unfortunately I lost the link and cannot give credit - but they deserve due credit for the info.

The link can be used to search for other part numbers.

I changed the 3rd and 4th gear pressure switches this weekend. I had to remove the battery and come in from above to get #4, because I didn't know how to unhook the wheel well cover at the top and didn't want to break it. Now I am wanting to change the fluid.
Question: if I do the change 3 quarts at a time, over a month, will it be OK to add the Redline fluid to the original transmission fluid?

dcmodels

CONFUSED - you stated above that you have a 2004 TL, and I wonder if you checked with a dealer for the correct part numbers. The part number you have listed just above, is not the same as the part numbers others (and I) have listed for a 2004-2006 TL. So, I have to wonder why you are using different part numbers than others are using, and have listed in this thread?

I found Redline fluid on Amazon and O'Reilly's sites. Amazon had Red Line 30505 D4 Automatic Transmission Fluid - 1 Gallon. Price $46 Is this the one to buy?

spiro007

Guys, as far as i can see, above are part numbers for 02-06 TL.
Does anyone know part numbers for 3rd and 4th gear pressure switches on 2008 TL?
Does 08 even have the same problem and i need to change those switches?

tom08tl

This is what I order for my 08 TL base.

Hey guys, just picked up an '07 type-S with 94k miles on it. I noticed the downshifts are a little rough when coming to a stop, but otherwise it shifts smoothly through all of the gears and holds them well even when I use the paddle shifters.
My question is which transmission fluid should I use? DW1, Redline? I would like to change it out a few times over the next month. With the higher mileage should I use anything else? This is an older thread so I figured I would ask for updated info since I will be swapping out the sensors and the fluid now. Thanks

Jboat

Hence the reason for my original post. The parts numbers were changed for some reason. That link states that the parts I have are the same, although the numbers are different. As to why I couldn't say. I verified same specs and pressure ratings (via the link provided)...One was beige/brown, one was black...

I installed them yesterday in like 15 minutes, but I honestly cannot feel any difference while driving the car. It feels the same...I guess that's a good thing.

I'm wondering how such a simple little part can fail in the first place. Is it the electronic sensor, or the actual valve orifice gets clogged? If the latter, then would it be possible to do a thorough cleaning with some contact cleaner and re-install?...Just thinking out loud...

Jboat

Another thing is the Ebay ad actually lists both part numbers in the listing...FYI

the correct part numbers for the 04-06 TL is listed in post #563 of this thread

dcmodels

Well, these two numbers may be the same part
OE No: 28600-P7W-013
Replaces: 28600-P7W-003

but I do not think that they are the same and CORRECT as posted by others and myself for an 2004 TL:
3rd Gear Switch
old#:
28610-ray-003
new#:
28610-ray-013

4th Gear Switch
Old#:
28600-ray-003
new#:
28600-ray-013

=====================
again, did you verify your part numbers with a dealer? why are your part numbers different from what others are using? just wondering.

If you feel you have the correct part numbers, then OK, its your car.

dcmodels

Because its a MECHANICAL metal part, which wears. Look at the disassembled pics I posted above in #574. That small round stamped metal part is NOT FLAT, its curved. It clicks to CLOSE an electrical circuit, under pressure. The electrical switch is normally OPEN.

The *clicker* is normally curved one direction, then under pressure pops curved the other direction. ) versus (

And I have asked twice that you verify your part numbers, because I think that they are *wrong*, and probably have a different pressure specification than the *correct* part numbers.

But its your car, and your responsibility to check the numbers - they have been given in writing in post #563 as pointed out more than once.

dcmodels

These seem to be part numbers for a 2nd gen TL, NOT for a 3rd gen TL. But owners must check the numbers for their own vehicle. Don't get confused by what is posted online, but check and verify the correct part numbers for yourself, preferably at a dealer parts counter, using your VIN.

Jboat

These are the parts I ordered based on the very first post of this thread...

I received the 28600-P7Z-003. I also received the 28600-P7W-013...

The link (which you provided) confirmed that the parts are the same...

So I don't really understand your confusion? Is the original #1 post providing the wrong part numbers? That's what I was going by...

I will call the dealer tomorrow and verify the are the same. I have already driven 150 miles with the new switches and it feels perfect like new...Hopefully they are the right ones....

Jboat

Why can't I edit the post? Here is the post that also helped me determine I have the correct 4th gear switch...

https://acurazine.com/forums/showpos...8&postcount=14

Also don't know if I matters, but I have an early 04 that was also part of the 2nd gear oil jet recall...

(Still plan to call the stealer tomorrow though...)

Thanks a lot!

Does anyone know if this affects 2G TLs?

Good question. I don't really know, but I have a feeling these pressure switches are specific to the 3G.

Jamus22

I would like to know if this applies to the 2G/2003 TL Type S as well. I need to replace the 4th pressure switch which might be causing my severe hesitation and would like to to this myself before paying for a transmission rebuild.

Thanks,
Jamus

Well, I was at the Acura dealer this afternoon to buy switches for my 09 RDX. The parts person stated that these switches are regularly replaced, and that the in-stock turnover is regular. The same part number(s) for my own RDX, also fit several other models such as RL, MDX, TL, etc. back to 2002. Which is why the parts dept keeps them is stock, and *sells* them regularly to the service dept.

The switches fail across all Acura models, according to the parts person, so why not in your 2G TL? the switches fail from use (wear), heat, poor fluid, etc. Read all of this thread, as well as other similar threads.

Fish63

I replaced my switches a couple of weeks ago in my 08 TL. I'm a new owner and noticed some shifting issues after purchasing the car with 47K miles on it. It took me a little longer than the average stated in the thread to complete the work, but it wasn't too bad. I will be able to do it faster the next time. There was a noticeable improvement in shifting performance after changing the switches and transmission fluid. I couldn't have done it without the information and photos in this thread. Thanks to all of the users for compiling.

The one issue I had during the changing of the transmission fluid was getting out the fill plug. I underestimated how tight that plug was put in: I put a 12-pt 17mm socket on the plug rather than a 6 pt and stripped it so I couldn't remove it. I had to fashion a custom funnel with a small hose to refill through the dipstick tube. It took a long time for 4 quarts of fluid to go through that little hose, but it worked out. Any recommendations on how to get that stripped fill plug out?

dcmodels

Remove enough parts to easily access the stripped plug. Then go to SEARS or another tool store - purchase one of the special tools for removing stripped bolts. Its a special socket that you hammer down onto the bolt head, then remove with a ratchet and extension - but use a breaker bar - not a ratchet, which may break itself. I doubt that the bolt will require more than about 100 ft-lbs of torque to remove, but brace yourself carefully - that is still a lot of force. I would also use a pipe extension on the breaker bar. And use a 1/2 drive rather than 3/8 inch, else you may break something else.

The problem is not the bolt - its not that tight. The aluminum sealing washer has galled/ cold welded both to the fill bolt and the trans case. Next time, lube the washer with ATF, then use 80% of the standard toque specified. Also use a new washer each time, for optimal feel and torque. The washer will crush, and an old washer is already crushed, so the fill bolt won't *turn-down* as nicely.

Thanks for this write-up. I will be tackling this as well as a drain+fill of the tranny fluid as soon as I can get the parts.

Did mine today finally...shifting went from annoyingly jerky to silky smooth,both at WOT and slower speeds.
