why does my car shakes in low rpm once in a while?

 

More details??? Can't tell you much by that description.

Voilent shake? Subtle shake? Frequency? Does it happen when you put it into Drive?

 

more info is needed. Any check engine light? Mileage? Last service (tuneup/plugs) What is the low rpm? 750rpm or is it lower?

 

sounds like transmission shuddering? motor mounts?

 

car has 181xx, types2002. it shakes for 2/3 sec on lower rpm,like in between 1/2 gears, like when i am going between 20/30 kms. it happens once in a while, i am not sure what is cusing this problem? i changed transmission fluid, cleaned egr valve. no engine lights, all the serive such as transmission fluid,oilchange has been done in time

 

i would definetly say violent shake,

 

if so, more then likely it is transmission shudder, try changing the fluid again, changing the filter, cleaning the switches, etc., etc.

 

transmission fluid changed 2 months ago, filters? air filters? and what switches? sorry i am noob

 

still try changing it out again (especially if it is still blackish looking, and not the cherry red that new fluid looks like), and ONLY use Honda/ Acura's ATF, nothing else really works in our cars (and basically all the members on here will say so too)


filter??? the transmission filter, it sits on top of the tranny, right below the intake tube (it's the black cylinder), switchs=the pressure switchs on the tranny (they get dirty fron dirty ATF), and also clean out the solenoids filters and such


and as will proably see, is that our tranny's are not the best out there (there are dedicated sections to the tranny issues on here) (in order for them to last, they are kinda maintence whores/high maintence)

 

Inspect your motor mounts, but it kinda sounds like a trans issue possibly.

 

can't hurt inspecting you motors mounts ethier

 

but i don't think it be motor mounts, cause he was kinda specific in where it was happening (and not happening at other shifts), and if it was mounts, it would proably be kinda harsh at idle too

 

yes only happens between 20/40 kms, 1-2 gears, and once in a while

 

idle? i get those harsh move once in a while when i first start the car, both goin forward and reverse,

 

Are your mounts original?

 

yes.

 

These mounts are typically good for 50k tops. That very well may be your issue. Front and side in particular and probably the rear with the miles you have.

 

i got 106k on my origionals (auto though ) and they are still perfectly fine (no harshness or anything)
