Hey so i have a 2000 TL with 225k on it, the car shifts just fine and i have no transmission issues or any symptoms of tranny issues the car shifts clean and ATF always looks clean I have no jerking or any symptom of a failing tranny.

Although i've been having a weird problem developing over the past 5 moths. At exactly 58 kph under light acceleration the car bucks/shudders back and forth.
I learn't to live with it, and have experienced it at a speed range from 40ph to 60kph. it only occurs under light acceleration, if gas is applied while the shuddering is going on it will go away, or if i let off the gas it will go away.
It doesn't happen every time I drive but it does occur 2-3 times daily.

Recently the shuddering has gotten worse, It shudders very hard so hard to a point where the sunroof rattles along with my windshield. My head hits the headrest back and forth like a rag doll it's really hard to describe how violent it is. It does it at the same speed, under light acceleration, except the shuddering has gotten a more violent jerking to it.

I'm embarrassed to have passengers in my car because it feels like such a POS like its about to die, I really wanna get this fixed because it unbearable and I cant take it anymore. I've heard it could be an axle, mounts but I really dont know where to start.

I've also been told it could be something to do with the Torque Converter but I just dont know where to start if anyone could help id really appreciate it.

happens to me too.. Just when i let off the gas going at low speeds

me too but its not violent, i just give it a tad bit more gas when it shudders a little but, but with 225k on the car i think the tranny is prob toast because your saying its very violent.

axle?

01tl4tl

have a shop put it on a lift and run thru the gears- tech will check the axles and bearings etc for you
Dont drive it like that!!!- violent enough to snap your head is a bad problem!!
Ask a local trans shop for an opinion
How are the motor mounts
Have you done any checking things yourself?

MOBB

I bring the car in regularly to my local garage they put it on a lift hit everything on the under body with a mallet and tell me everything is ok. It started out as a small annoyance that nobody knew other than me. But now its turned so bad that I swear, my sunroof rattles along with my windshield rattles and my head is hitting the headrest back and forth and my girlfriend in the passenger seat thigh's are jiggling lol I swear.

My dad also owns a 2ng gen and has the same problem as me but his shuddering is barely noticeable compared to mine under the same circumstances.

I just wanna know where to look first so I can take it from there because I cant go on with this shuddering its just unbearable. The guys at the shop are just clueless and dont have a clue what I'm talking about and ofcourse when they drive it the shuddering never happens.

01tl4tl

take it to a better shop, one that doesnt just hit things!!

You have a speed-rpm rotational imbalance somewhere- could be innner cv axle bearing
or who knows
A good mechanic owns a special stethascope and has the car running and turning the transmisson/wheels in the air- listening to each place there is a bearing

Has the shop checked for any codes?- dont need a warning light to get a fault code.
If not- go find a real shop and pay for diagnosis

If amount of gas pedal pressure changes it, you may have a trans shift selenoid or torque convertor problem- ones external ones internal~

If all else fails take it to acura- they can diagnose it correctly and save you money in the long run--is it an easy fix or a major problem
Something slams me in the car and rattles the sunroof??--not an easy fix if you have been driving it like this..making the problem worse as it puts strain on the next part to it

Get the wheel bearings checked as well

My 2001 CL-s also does it .. it is also under very light acceleration at 60MPH when accelerating SLOWLY... when deceleration nuttin and when accelerating fast nuttin just when i hold the gas at 60MPH.. I just had the tranny replaced so it is not the tranny..!! I am thinking its the wheel bearings but have no $$ to fix it right now and no Money just to throw at parts and guess what it is! If anyone figures it out let me know but my guess would be

I've always thought it was the transmission since I've got 188k on the original and the shaking is the only problem I have with the car.

But then again, my mounts are busted and nothings ever been replaced

StonedCL

iTrader: (1)

My engine mounts are good my tranny is new and tranny mounts new, my fron sway bar has new bushings, my front has new sway bar links shocks and springs so i think its that axel whatever they call that pic i posted.. Its funny cuz no one in the car notices it but me and if i hold the gas at 60mph thats when its at its worste deff feels like the tranny is slipping catching missing whatever u call it. The tranny otherwise shifts fine downshifts fine upshifts fine and no shuttering shaking when slow or really fast 75-90 just at 60 MPH it seems maybee 55-65 but only when foot on gas to maintain speed as soon as i step on it , then it goes away!!...wierd!

Mine doesnt shake at those speeds. It shakes at ~30 usually when I accelerate slowly.

ChucksCL-S

I've got it too at around 60mph with light aceleration, worse going uphill. The problem is still there with a new tranny and new axles, I'm stumped.

gold2003tl (90)

i only get shuddering/shaking at low speeds under 40 mph coming out of 2nd gear into 3rd and coming out of 3rd into 4th. sometimes iv gotten a little shaking coming out of 1st into 2nd.

i never get it at highway speeds or anything violent, again.

01tl4tl, it is simple to replace a few solenoid valves that may solve this shaking, i just give it gas and the shaking goes away. i suspect its a solenoid or something that has to do with changing the gears. other than that like you said the tq converter might be the only problem which i dont think it is.

fsttyms1

Shudders are usually the trans, axle, motor mounts and in some cases the motor. My guess is the trans or axle. I would think if a mount were that bad where you get that kind of shudder you would notice it just shifting out of park

StonedCL

iTrader: (1)

It does feel like the trans a little but I just had my trans rebuilt..
It is funny cuz it is only at 60MPH... It is really getting annoying..
If it is the tranny what would it be ?? Not the pressure switch or any other soliniods? It would not be the torque converter either, would it?

01tl4tl

why dont you let the trans shop check it out-- stonedcl?
There may be a prob in the rebuild

fsttyms1

Id bring it back to the trans shop and point it out to them. It very well could be the trans even if you just had it rebuilt. It could be the tq converter?

01tl4tl

I always suspect the last work on the car
Maybe the circlip on axle wasnt inserted, or the TQ is bad, or even a new or rebuilt cv axle can be bad

MOBB

I have the exact same symptoms as you. My tranny is butter smooth above 30-40mph, I never get any shudder at 60mph, just a lil from 1st into 2nd den a whole lot from 2nd to 3rd. But there is no jerk or delay in shifting. This also happens when set at a constant speed and rarely when delecerating at around 35 mph. Im DONE with this POS and trading it on for a silky smooth shifting 2003 NBP TL!!

01tl4tl

an 03 lol that'll fix your problems~

I'm getting a medium shudder around 40mph (from 3rd to 4th gear?). My tranny was replaced at 37k miles in 2005.

Any chance this could be due to my plugs? They are the originals and I'm at 140K miles. I will be changing them in the next month.

VTEC11

Mine does the same thing too. I've noticed a shutter going from 3-4 gear, usually only when cold. I put it in SS mode and when I reach just under 3k RPM it shutters even without shifting the gear!

i have a 3 year warrenty so i guess im not really worried about the trans being the problem, but I should have them look at it...
I never really drive 60 or stay at the same speed so it really does not bother me too much, NJ traffic will not allow u to drive the same speed!

If it was something to do with the trans I hope its not something that they will need to rip the trans apart to fix!

gold2003tl (90)

im bringing mine into teh stealership Friday, its been getting worse and its just annoying. i am still covered by the warranty so i might get a freebe. if not i might get rid of the car sadly.

if they rebuild to for free or very little i am keeping the car and doing a 6 speed swap in the summer next year, if they cant fix it for free then i might just have to live with it or get rid of the car. if they tell me nothing is wrong with it again i might stick it out for a while or trade the car in for somthing like 3gtl, tsx or an rsx. i am really disappointed, but what else i am going to do. my tranny is slowly failing and its not going to last too much longer i bet. either get a more reliable car or wait until i have to pick up gears and clutch packs off the highway.

speedemon90

I have the same problem except mine is not that violent. But for me this tends to happens on inclines. Also i never get it at 60mph, usually like 30-45 while doing light acceleration around those speeds. But yea I remember reading somewhere that this happened and some guy said the axle may need to be fixed and thats a common problem on our acura's

TL

I noticed this recently too. Going up a hill around 50-60km/h...gentle throttle, there will be a vibration. A remedy that works for me, is to use D4 as opposed to D5 at these low speeds. I suspect it's actually the 5th gear that's causing the drone. I also found the following service bulletin which is for a newer generation TL, but seems to describe the same problem:

http://www.in.honda.com/Rjanisis/pubs/SB/B05-017.PDF

At the same time, I did a search on Google and noticed a lot of MDX owners are getting this problem also. Some ended up pointing the problem to the torque converter. Please keep us posted after you visit the dealer!

Im pretty sure its the transmission.

I studied the symptoms more and I found that the more violent shudders occur around 35,36,37 mph in 3rd gear going on a slight incline. My guess would be that the tranny is trying to shift into 4th but wont because its designed to shift at 40 it fails.

gold2003tl (90)

i get it in and out of 3rd gear at like 25 - 30 ish. i get it while its in gear too not just shifting in between gears. i sometimes get it around 40 mph 4th into 5th, but thats rare.

i think my torque converter is shot, cus it does this whiles its in gear.

speedemon90

You know thats not totally accurate because if you do the same in triptronic mode and stay in third gear and go those speeds you get the same effect. And since you have control of it, it cant be the reason you explained right? It could still be the transmission.

SLushhYYY

iTrader: (8)

^^I dont get the shudder in Sport Shift

gold2003tl (90)

^ iv gotten shuddering in tiptronic, tho no were near as much as in d5

MOBB

same here bro car shudders while in gear, It also does it in Tiptronic and has a sweetspot at 25-35 mph.

Im 100% shure my torque convertor is finished, Im really glad I sold the car today, Ill be getting a newer 2nd gen though!

thinhthan

ya for some reason my car does the same thing. sometimes like when im driving with the gas on i can feel my car jerk back and forth but its not a really hard jerk. its just a slite back and forth movement

SLushhYYY

iTrader: (8)

Im gonna take my mechanic out for a ride today. Maybe he can figure it out.

Thanks soo much that Service Bulitain that you posted was EXACTLY what is happening to me at THAT exact speed that it mentioned..So I am about 80% sure that is the problem with MY car cuz like I said the transmission is brand new.!!

This service Bulletin 05-017 applies to 2004TL's and up will the part #'s and this bulletin be ezactly the same for my 2001 CL-S?
And will P/N # 50207-sep-305 be the part # that I would have to order for the CL??

Thnaks soo much!

StonedCL

iTrader: (1)

I searched ACURAOEM parts and could not find that part P/N # 50207-sep-305..The bullitin describes exactly what is happening to my Car so might as well give it a try if it does not cost too much for that part!

TL

Since the service bulletin is for the 2004 TL -- I have no idea if the part will fit for the 2nd gen TL. You might be able to bring it to the dealer and see if the vibration you're experiencing is due to the same problem. But, as you said, the symptoms described matches the problem exactly for my TL as well...

gold2003tl (90)

i went to the dealer, they went for a test drive with me and they got it to shudder. they said thats bad and that i need a new tranny. i am waiting to hear back from them if i can get a goodwill.

they told me that the 3rd gear clutch pack is breaking apart into little bits and f-ing up everything.
