For anyone that changed the switches on a 07-08 TLS: I looked at the pictures in post 592 and 593 and finally found the 4th gear sensor (28610-RKE-004). However I can't get my hand on it enough to disconnect the wire. Any suggestions. I haven't located the 2nd and 3rd gear switches (28600-RKE-004) yet.

Running into a problem:
I have a 08 BASE TL and went to my local Acura and asked them for pressure switches for 3rd and 4th and they gave me one of each of the part numbers listed above with two washers.
I read on this thread that the switches are #12 and #13 in the diagrams.
However, at Acura they printed me out a diagram and showed me that the switches that need to be replaced are #13 and #14 so here's my question: Why are they the part numbers exactly as listed above but not #12 and #13 as people say on this thread?

I asked if I needed 2 of the part number 28600-RKE-004 because it even said that there was 2 switches on the diagram for #13 and they said "no only change 1 because we don't mess with the other one" And I've looked through the whole 19 pages of this thread but can someone tell me if I have to pick up another sensor for #13? And my main question is why do they tell me I have to replace #14 if its the same part number as #12 supposedly?

Please correct me if I'm wrong about anything.

My '08 base 5AT TL is CPO with about 28k miles on it. I've had it for about a month. Should I change out these switches/senors now or just before 50k? I do all city driving and don't really go past 40 mph (lots of lights/stop signs, pot holes, speed limits etc). The only thing I really noticed is the shift from 1 to 2. Seems to be a slight delay.

Would the new honda ATF DW-1 be a good alternative to Redline? I ask because I have 6 quarts in my garage. Could I do a 2 X 3 with DW-1 and do the final 1 X 3 with Redline Type F instead of doing 3 X 3 exclusively with Redline? I am experiencing the shudder problem and would like to begin to address it before it is too late.

bro why would you do 3rd and 4th switch when your 1-2 is lagging LOL....

1-2 will always have a very very little lag...which is more pronounced during cold shifts (when you start ur car and stuff).....

as a preventive maintenance I would suggest you to change the switches at around 60-70K miles....I would switch to redline ATF thow...if you are worried about the bad reviews then I would switch to atleast DW1....

your completely the other way around....how would a stock fluid be a good alternative to an aftermarket fluid....

i do understand what you saying thow....redline is a great fluid...am running redline ATF type F all the way....i love it....absolutely....Inaccurate did experience some flaring so he added a little redline D4 to it....you can do it as well...

so to get a 66% of type F and 34% of dw1 when doing a flush (12 qts) use 4 qts of DW1 and 8 of redline type F....so each drain and refill will have 2qts or redline and 1 of DW1....

I don't know man, cars are not my strong suit. I guess there's no 1st and 2nd gear pressure switches to swap out then? When do 3rd, 4th, 5th gear kick in (RPM and/or speed wise)? I rarely go over 40MPH in the city. Just wondering if the other gears even kick in.

I replaced my switches this weekend in my '01 CL. I had about 50k on my latest trans. They fixed the bad shifting condition. Thanks for the tip.

abirvalg

05' w/118K pampered, hand washed, zaino treated and amsoil lubed since day1

per my request dealer started draining and filling with Amsoil AFT at around 35K every other oil change

just under 100K started to hear a ringing wistle while pressing on the gas
didn't think much of it, asked the dealer thay said a belt, lubed it and the wistle was still present, i didn't push the issue

around a couple of weeks ago started to feel "rough patches on the road" that weren't there before

tried to analyse where the vibration is coming from, felt like 4th or 5th, more pronounced going up hill

did the damper TSB myself, it reduced the overall vibration, but didn't do anything for the one that i was concerned about

stumbled upon this thread among others and did some more testing
zeroed in at 1500-2000 rpm, 35-45mph, 4th gear only accompanied by the ringing

i've also noticed my ATF getting very dark
had a dealer drain and refill with z-1

next day i went back and brought some Amsoil with me and also a box of "sure shift"

they did 2 more drains and refills mixing 2 parts regular with 1 part type F
and replaced the switches

AND .....

the f..ing vibration is still there like nothing happened
it may have softened just a little, but i still "hit the washboard" every time 4th kicks in

next i'm going to pour more type F into it .... this time heavily mixed with tears

why does the 07/08 TL have 2 third gear switches?

iTrader: (5)

^^^ acura might have tried to fix the problem

koain

you may be right I got the check engine light with the flashing D. autozone checked the code and it showed a faulty 3rd shift sensor. Didnt say which one so I'm left to assume the second switxh is the fallback if one goes out. the trans shifts great but I ordered all 3 switches and will replace them first warm day of the month

smart move...

abirvalg

more type F didn't help either, even though i held the tears back for the most part

also my service manager told me it's hard as hell to get good wills out of honda now

good luck to those who's trannies are still working!

rudboy00

I think they used RL Tranny's in 07/08 TL's Thats why its a bit Different from 04-06

Scottwax

Since you may need a transmission, save the money you spend on Zaino and get Duragloss, that's who makes Zaino anyway.

DG 901 = Z7
DG 101 = ZAIO
DG 105 = Z5
DG Aquawax = Z8

Sucks about your transmission issues.

Bearcat94

It's adapted from the RL trans. Not a direct application.

koain

it could be a trans sent from heaven....but why 2 third gear shift sensors?

^^^ coz i told acura your 3rd gear sucks 2 times

koain

thats how I'm beginning to feel about my TL LOL

Isn't it obvious why there's two?

Good info.

03bl AC k CL

i have been looking everywhere for this thread, i remembered reading it a few years ago, and now I am looking to buy a 1999 3.0 CL. its a 4 speed AT, and if i purchase it the first thing I am going to do is have these sensors replaced. My question is, what sensors should I have replaced on the 4 speed? is it different than the 5 speeds?

spineman

03BL I believe this thread is for third generation TL transmissions. Don't think that replacing the sensors on the older ones was an issue. Check out many threads on the the 2nd generation CL TLs tranny problems.

I hate cars

Replacing the switches on the 2g is most definitely an issue. I've cured a couple 2gs of shudder and flare with the switches and fluid.

The 1999 CL is a 1G. The 2G CL is 2001-2003.

03bl AC k CL

That's a relief to know replacing the switches will help. This is a 1g CL though, and like I said it has the 4 speed auto, (similar to the 99 TL), I am just curious what switches I should have replaced on the 4 speed? I am going to look at the car today, and can most likely get it for under $3k and my only concern was the tranny.

I hate cars

If they have pressure switches they will benefit from replacement.

Majofo

Very similar. You should still be replacing two pressure switches.

03bl AC k CL

I just test drove the cl I would buy it today, but can somebody please locate the pressure switches for me on acuraoemparts im not sure what the part would be called. I would appreciate it greatly because like I said I would buy the car if I can purchase the switches

two weeks ago I got the check engine light with the flashing D. autozone said it was a 3rd gear shift switch but thye code didnt specify which one so today I finally replaced all 3 switches on my '07. I've noticed I have more engine braking now and not as hard downshifts under braking as I approach a red light. Before the tranny shifted out of 3rd into 4th gear after only seconds. It was an extremely fast upshift to 4th no matter the throttle now it holds 3rd gear longer. Car seems more taut and responsive and the shifts are smoother even tho im using dexIII fluid.

since I changed my switches I noticed that my downshifts from 5th to 4th and from 4th to 3rd as I coast or brake to a red light jump about 400 rpm...is this because of the dexIII im using or is it normal....my lexus rx330 downshifts are barely perceptible

I hate cars

That's the way it should be. The more aggressive fluid actually makes shifts nicer but quicker.

It's grade logic. All TLs do it, it's in the owner's manual. It downshifts as you're coming to a stop, especially when you're on a decline but also under normal braking. It's marketed as a feature to help slow the car but IMO it's there to slightly improve mpg since the fuel injectors shut off anytime you're coasting and the rpms are above idle.

koain

Chicago has no declines...part of the reason Illinois is called a prairie LOL....its a bit disconcerting to feel that jerk as it downshifts but same as you the dealer said thats normal even with the z1 before i changed it when I went to complain

I hate cars

It's normal, mine sometimes goes through phases where it downshifts more sometimes than others under seemingly similar conditions. When on flat ground, I notice it more under light braking. The dealer will say anything is normal even if the car catches fire but I have to agree with them this one time.

koain

the lexus does gear hunt more than the acura but the shifts are smoother and less perceptible which is a more pleasing driving experience even with the gear hunt around an interstate on/off ramp...I guess acura took a half hearted attempt at the off road rally enthusiast by marketing the car for the couch potato LOL

I hate cars

That sounds about right lol. Almost forgot, I went to Chicago once to pick up a car (Turbo Trans-Am). I flew out of Vegas, already up for 48hrs straight. The couple was very nice and took me to a great and supposedly famous pizza place. By the time I was halfway back to Vegas I had been up for 72hrs straight. I wish I could remember my one time to Chicago but I barely remember a thing. It did seem flat as you said. I ended up hitting a deer in some state between there and NV and smelling burning deer the rest of the way back. That was a rough trip.

koain

hitting deer is a wisconsin experience...shooting them too

I have an 2008 TL Base 5AT currently at 60k. Two Questions:
1. Since it has 3 switches now, do 07-08 members still change them out?
2. Where is the DIY for the 07-08s?
