about 2 weeks ago i felt when i would go into 3rd from 2nd the 3rd gear slipping not being able to catch on to it or something cuz the rpm went up and down a little.........so when i drive it now or even ss i have to rev it high so it doesnt do that slipping....then i changed the tranny oil one time and waited for it all to come out and poured it with redline racing atf......i felt it help a little......and for some reason the fluid wasnt good enough when i checked so i ended up pouring the whole gallon in terms 4 quarts and would tht b a reason why the check engine light came on?thanks for the help

Check engine light will turn on if u added too much fluid. Transmission has an overflow sensor.

Go to a parts store now: Codes come from many things
(I wasnt aware of an overfill sensor) How long between the refill and the ck light?

Might come up with pressure switch code or who knows what
Its free- just go to any major type parts store and ask for a code reading-
you have a Ck eng light on
Report codes back here

you are at least .6 of a quart atf overfilled!!
system drains 3 to 3.4 qts depending on fluid temp and your patience allowing it to drip out

best way to ck level is from cold- drive casually on freeway 15 minutes
get off and safely park, level surface, in Park, engine OFF
remove and wipe stick- reinsert fully-

should read BETWEEN the dots--if at upper dot its at MAX,,
anything over definetly needs to drain out..middle to upper range preferred at this `15 minute drive` fluid temp- the indicated level changes with temp!

I would start with draining half a qt out before anything else, then test drive to get codes read

The slipping may be the clutches, but your description of using high rpm to force it to engage a gear is odd,,may be shift selenoids/pressure switch clogged or failing

Why did you use redline- you were trying to cure the revving before it grips?

please clarify:
light throttle,,slips on upshift? would normally shift 2000 rpm

medium throttle,,slips on medium throttle- normal shift point 3000 rpm?

so you have to keep on the gas to make it shift, or you let off and it grabs?
SS mode does what up and down?
mostly 2nd and 3rd?

Miles on car/trans?

JohnieG87

Most vehicles have one to alert you of overfilled occurrence. Wouldn't want u to drive of with two quarts overfilled. I may be wrong, please inform me if I am.

based soley on reports of trans suddenly puking out fluid and no indication of fluid problems, low or high
Im going with: no we dont

simran4h

it tends to slip when im in third gear and the rpm is around 2000........it goes up and down the needle.....and it shifts perfectly fine around 3000 rpm

I contacted the Acura dealer here in Iowa, explained my whole situation, ie. 8 days old, etc, he said they couldn't offer any sort of discount and that their current rate for replacement transmissions is $5500.....

Guess I will keep looking.

fsttyms1

Ive havent seen one yet.

closetprisoner

Should look into changing the pressure switch on the transmission.

01tl4tl

bill- who did you speak to at the dealer- the service writer or the actual service manager?
manager can do whatever they want- call corp for help

writers get paid on commission and will always tell you full price-- and no help available
Would you like an appt. saturday sir?

but you didnt buy it there, and have no history of spending money with them , so no reason to step up for you now

BillThyCat

I asked for the manager as you had suggested, took him a few hours to get back to me.

I tried the guilt trip, I had only had it 8 days, that I wouldn't probably buy another Acura, etc. Said he was sorry but there was nothing he could do and their current average was the $5500.

My mechanic called and talked to them yesterday and they told him not only would I need a new PCM that there was some fuel regulator that was required with a transmission change as well. Anyone ever heard of the regulator being a required upgrade at the same time as a transmission change?

They quoted $1000 for those 2 parts alone, and $3300 for their reman'd transmission.

My mechanic has found 2 places that sell rebuilts that he has dealt with before, only one of them mentioned the PCM upgrade, and it was only mentioned as a service bulletin, and when I researched that bulletin, it was the one on the extended warranty which mentioned nothing about the PCM.

Does anyone have specific knowledge of when the PCM needs to be changed? Does it have a bearing on which transmission is used, ie the newer 2004+ redesigned transmission, or is it just an upgrade that improves the life by using the new shift points.

I have tried searching and haven't had any luck finding the VIN info that someone mentioned, the service bulletin has a list on VIN's, but for 2000 is says All. It was 2003+ that had VIN ranges. Not sure if this is the same VIN range that was mentioned or not.

Thanks again everyone,

the extended warranty effected all 2000-2002 and early 2003 production dates

the pcm vin list is on our diy page

For you- I would go with the honda trans swap- oddessy or accord
get a good used unit from auto recycler (junkyard) for cheap
and have your guy drop it in

01tl4tl

the case design was in 2005 not 04
we refer to it as post 2/05 units, but we dont have an actual date of the change

BillThyCat

Sorry, I guessed at the dates. My mechanic asked Acura about the Odyssey and Accord transmission, and they said they didn't know of any other compatible transmissions except the one from Acura. Junkyards have pretty much told me the same thing. I wish someone knew for sure and would post it on here for the rest of us to get value from.

Is there any difference in part #'s between the original and post 2005 transmissions, so that if we do go the way of getting one from a junkyard we can tell which is which?

Which DIY is the VIN list in? I was pretty sure I looked thru most of them. Is it in the big thread on transmission failures? or in the DIY?

Thanks,

BTC

01tl4tl

no its a seperate thread inside the diy list with vins of the more popular recalls, failures etc..may say PCM vins
the whole diy section is only the 2 post by fsttyms1 (kris) and all the direct `click to access` thread links are inside those post

of course acura told you no swaps!!- they want max money for what they sell
AND they dont do swaps as a normal course of jobs. They do what the book has times for and wont clog up the shop.
Most times they would try to rebuild your engine rather than drop in a used motor!!

May also be corp rules on franchises not doing that type of work--who knows~

Small private shops, `import tuner` shops- they will know and have done them in the past

dealer does what the corp repair books says... and thats it

just because local junkyards are not informed doesnt mean its not true!

Ziners who have done this please step forward- we need numbers/answers
considering how many accord parts- struts, cat and more- crossover,,not shocking a trans would bolt up to same engine case design,,they dont want you to know about!!

the 4 cylinder honda guys are always on the lookout for a TL/CL engine to drop in

pickler

my friend has a j32 in his crx, i can't see why a 5 speed auto oddessy tranyn can't replace a 5 speed auto tl tranny :\

BillThyCat

Does the engine size, i.e. 3.2 or 3.5, matter when it comes to matching up to the transmission? A lot of the Odyssey's I saw had 3.5 engines is why I ask.

I would assume you would need the PCM off the donor vehicle as well for it to properly talk to the transmission?

BTC

01tl4tl

Im going to guess acura used the same engine block for decades now
with different cylinder bore linings and larger pistons, you can make any cc you want

my.daily'tl'

Has anyone seen AV6 around? Piggylover? Ihatecars? Phee? I bet he knows what bolts up and what doesnt. I think av6 did the av6 accord trans. I think ive seen an 07 accord trans in one as well.

This thread needs to get down to the nitty gritty.

simran4h

I need insight.....if I do the accord swap...will tht transmission be good or will it end up like the tl transmission?

My 2002 TLS also seems to be slipping between 2nd and 3rd. I've had the tranny replaced in 2008 so it's supposedly the "new tranny fix". When I'm driving around 2000 rpm the car starts shuttering and shaking like it can't get into 3rd gear (especially go up hill), but if I'm driving at 3000 or above it shifts perfect. I was putting 87 octane gas in, and since I started putting in 91 it seems better, but it still does it at low rpm. Does the tranny fluid need replacing (can't remeber the last tim ethat was done)? Just trying to figure out a cure. Maybe I can drive in sport shift so it shifts at a higher rpm, but don't really want to do that all the time. Thanks.

BillThyCat

Why would you use 87 octane in a car designed to run on 91+ octane fuel? Are you using an octane booster additive?

If you step on the gas when it's doing the shuddering, does the RPM rise and the vehicle not increase in speed? That would be a better way of determining if it's the transmission or just the vehicle having problems burning fuel.

Do the seafoam treatments in the gas and see if it clears up.
