If the tranny slips going into 3rd in automatic mode but works fine when you manually shift,does it still mean 3rd gear is gone? What i don't understand is that, how can a tranny shift well in one mode but not in the other??

Maybe when you shift in auto, your foot is still on the gas, but when you shift in SS mode, you take your foot off the throttle as if you had a manual tranny, so the slip isn't as noticeable?

No! In auto the rpms keep going up but when i shift using tiptronic,it shifts fine.

each gear set is on a seperate shaft with clutchpacks- stacks of clutch disc- on each end
You can wear out just one set of those disc depending on how you drive- if you like to downshift at high rpm into 2nd or 3rd--that'll do it to those clutches and the car wont hook up on accelleration

ck the fluid level and smell- burnt? = bad news
just old- try change 3 qts of fluid with Honda atf,
might need to clean selenoids

read the main Tranny Failure thread for other fail symptoms to see how bad it is
If slipping for real- revs and barely moves forward--its trans time

What year and K'ms do you have?
Oil jet kit installed? that was the recall in 2004 and I think Canuks get some of the extended warranty coverage usa cars went to court to get

No idea why it acts different unless its rpm and throttle position differance

ps- dont lift to shift up in SS mode- it wont let you over rev and is made to quick shift on the power

The car is an 02 and it's a US model. My friend bought it 2 years ago.
He told me exactly this: When he drives in auto mode,his rpms go up when it's time to shift from 2nd to 3rd so,he puts it in ss mode and there he's able to shift.In ss mode there's no issue whatsoever. My thought is,if the tranny is truely fried,it would slip ALL the time not some times and never in ss mode.
I'll smell his tranny fluid and see what it smells like.

SS mode is simply an electronic signal from the shifter to the computer requesting a shift- then computations are made about rpm and car speed- allow or ignore the downshift (as example)
He may be getting it to shift with SS but its not ok for sure!
Ck the recall install of oil jet kit, you can call a dealer with VIN and ask if thats been done

Otherwise get it to dealer ASAP
read the last few pages of `Tranny Failure thread` here for advice on `Goodwill Warranty` in case he is just past the 7 year 9 month since car first sold new

1st timer

the car was imoprted from the states so he has no warranty.

ahh I see- info like that is helpful in first post
Are you close enough to the border to get to a usa dealer?

if not - start looking for trans shops for a rebuild- it may not need too many parts but they replace whatever is close to limits so you can often get a 2 or 3 year warranty

at the least get it to dealer for the recall install of oil jet kit- that should cross over counries as it affected TL's everywhere

1st timer

I did ,in post #6. Border is about 1 hr away. But i don't understand why it works fine in ss mode and not in auto!

JPortillo90

Thats how i killed my first tranny... using that SS mode shit. i think that was just my neglegance though.

post 6 says its a us model but doesnt say car lives in another country- which has an effect on geting service

You can wonder all day long why a certain nudge into gear works but the fact remains its going for the dumper and soon

1st timer

it's been like that for a year.

01tl4tl

then why are you here using bandwidth?
Your friend doesnt care about the problem or a trans shop would have looked at it
within the last year!!!!!!!!!!

Mods can we make a rule?: no dual citizenship/ ex-pat cars without warranty-- and warranty questions?

My tranny seems to slip going into 5th I think and only in city driving, so in the city I drive D4 and highway i drive D5

speedemon90

And I havent heard the grinding noise in a long time, unless i hit traffic on the freeway and i forget to switch back to D4 ...I get less gas mileage but I have a working tranny!

1st timer

He was just wondering why it works in ss mode and NOT in auto mode.

01tl4tl

Im thinking maybe shift selenoids dirty? many ziners have cleaned or replaced theirs- ck the threads or diy list
There are a couple of the selenoids

If there is glaze or crud buildup from lack of fluid changes- it may not be ready to shift in D5 but the request signal in SS forces it

Kris- what do you think? selenoid?

kriz2fer

Is there a diy on the selenoid cleaning? i have looked but never saw a diy...i want to clean mine

01tl4tl

replace if its shifting funny - probably DIY for that- I know gen3 has a pressure switch diy
look for anything thats similar to an engine oil pressure switch-with wire and connector

fsttyms1

I dont understand how it works in SS and not auto? SS is just telling it when to shift. It doesnt effect how it does it. just like gate shifting. Does it slip when gate shifting?

kriz2fer

found it thanxs

can't seem to find the solenoid on my car. Is it the same for 00 and up?

I think when you shift it manually, the line pressure control solenoids(linear solenoids) max out the line pressure so it won't slips unless your 3rd clutch pack is wasted. If you put it in auto, the line pressure is being control by the computer according to the TPS. Anyway you 3rd clutch pak is having problem. What happen is your 3rd clutch pressure is getting weak, as the trannny get older, it got some debris from converter, clutch material got into the pressure switch and clogging it up, it will cause the 3rd clutch pack to burn as the pressure get weaker. The 3rd clutch drum locates in the rear of the transmission, if you took out the back cover you'll see it. You can fix that without completely open the transmission.

piggylover1985

Your 3rd clutch pressure switch locates in the lower section of the back cover on the tranny, is has a little metal shield cover it, if you take out the two 10mm bolts, then you'll see it, it's the same on all Honda/Acura 5sp auto, it is the only switch that can be loosen with a 22mm wrench, or adjustable wrench in the back cover.
