Hi,guys,my frist time posting,hehe.
I think there must be some problems with my accord.It's a 92 EX-R.with 160K kms on it,I am not so sure about miles,maybe like 100k? I had a vibration feeling when I was at like 60KM/h, I can feel at my gas pedal and likely it's from the lower front engine compartment. Like everything else is fine,just when I am cruising,with the gas pedal 1/3 down,the vibration happens,if I release the gas it or rev it up more,it disappears.It happens at about 1700-2200 RPM. It really bothers me.The car has been lowered,I have done the tire balancing,change the tranny fluid,what else? Idle is normal as well. It's an automatic by the way.
Any idea guys? Thank in advance!

 

Maby since you lowered the car you should get the chambers corrected and check if your wheel bearings are seized up

 

thank you for reply,I will go check it out.I think it might be the transmission problem..... When I put it in D4 and drive,there would be a bit bigger down shift at 2200rpm to 1500 rpm when I release the gas pedal at 60 KM/h. If I put in D3,the problem goes away.The down shift is strong and you can feel it since the car will rattle once.Any idea guys? Really hope there is no major problem with it.However,I changed the tranny fluid yesterday,the problem still persists..........

 

the same happens with me...i figured it was my tires so i had them balanced, but it will still shake at times...maybe its the torque convertor....

 

thanx man,yeah,now I kinda believe more it might be the tranny. Is there any simple way or let's say cheap to solve it? Send it to a mechanic is too expensive.....

 

i could honestly care less if my tranny goes [edit: i would rather it didn't go out...i dont need the bad luck right now...road trip this weekend]...itll give me a reason to stick in a 5spd f22 or h23 tranny

 

It could be a number of things. it could be the tires out of alignment or a bad motor mount or bad wheel bearings.

 

yeah,but all the problems seem to disappear when I put into D3 instead of D4, I am still worrying about the transmission though.......

 

My guesses are the following:

Rear motor mount
Alignment needed
Tire balancing
Tire pressure
Wheels not on the entire way

IMO I would get your tires balanced and rotated then get your alignment if you haven't for a while. Also check tire pressure and that all lugs are torqued to spec. If it still persists check the car at idle if the engine shakes.

If it is at certain speeds typically its your tires/alignment/pressure.

 

thanx for reply,yeah,I will get my tire balanced soon.But still I am confused with the D4 and D3 problem,how come in D3 everything is fine,but in D4,vibration,harsh down shift........... really bothers me a lot.any idea? thanx in advance guys

 

It could also be something with your suspension, what did you do exaclty to effectively lower your car? Just new springs?

 

Also when was the last time you replaced your tranny fluid...if your shifts are hard it could be related. You need to give more details.

 

sorry guys,I can only post 5 a day..
yeah,I replace the tranny fluid 3 days ago.However I think maybe my tranny needs a flush or something,not just change the fluid once,this not gonna do the job.These 2 days I drive in D3 which turns out to be good,good response,smooth shift,much better than in D4.I am still wondering what really could be the problem.Cauz the solenoid in D4? I have no idea about this.
