tranny 'jerking' Options

[Malhar95]

lets say you put your car in neutral (N), rev it up to about 2500 rpm, and then put it in drive (D).
you know how the car jerks and shakes the whole car because of all the power jumping into gear.


well my cars been doing that once every other time i switch from N to D.

the engine doesnt really rev but it still reacts asif im doing so.


however its not constant. heres an example of today of when it did that.


started the car this morning,
reversed out of driveway,
put it in Drive (nothing yet, acted normal like its suppose to)
went to the gas station, put it in P
filled up,
reversed since there was a car in front
put in drive again (and it 'jumped' as if i was reving the engine)


any advice of what it could be


on a side note:
my cars making this "dhuck" sound when i accelarate from a stop or decelerate from speed,

its hard to explain in words,

d-man saw it and thinks its something with the tranny, but since i drive it more, i dont think so since its not coming between shifts.


it feels as if everytime the the tranny goes back, it hits something strong but small (like a bolt) and them when im slowing down, its hits it again


this probably doesnt make sense but i figuered if maybe u guys can give an oppinion

my car did something similar when i had the tranny to throttle cable adjusted way off. i adjusted it closer n reset the ecu. it helped.

but in your case, it sounds like a bad front or rear motor mount
