    Posting this about my wifes car I just bought her, we were driving a couple weeks ago for a long drive on our way back home as we came off the highway it started jerking as it was going into 2nd 3rd gears I think in between 0-80km beyond this speed we did not experience it, I changed the transmission fluid and filter 4 weeks ago no problems until 2 days ago she was driving and told me it happened again, I did some searching on the net and found out it could be a transmission pressure sensor? any info would be great thanks guys!.

    mine is doing the same thing, studdering at 30 mpg when light on the gas pedal. only after its warmed up. feels fine when cold.

    i have mine narrowed down to the pcs or tcc solenoid. they both live in the side cover of the trans. dont look like fun to get to.

    im going to a trans shop to have it scanned, so i can be sure thats what it is for sure. but im feeling thats going to be it tho. and get a price to fix it, if to high i guess ill be doing it myself.

    trans codes can only be read by a trans scanner, so the auto zone free scaner wont work, and the check engine light wont come on either, as far as i know so far anyways. mines still off.

    I was reading about the pcs location on one forum is it true that we have to drop the tranny to access it? seems to be a known problem with these,
    thanks for the reply!.
