I replaced my conductor plate about a year ago and filter and oil and plug but now about a year later car seems to shift weird when down shifting and when going slow from a stop if I dont accelerate it seems to jerk back and forth but not much but if I go and increase speed it's fine there's no check engine lights any help would be appreciated .

I would do the adaptations reset search for sneaky ecu reset. It resets the TCUs learned adaptations and can sometimes fix weird shifting

Hi. I am new here and this is my first post . By trade I am an Automatic transmission builder and Auto Instructor. I can tell you that when doing the TCU relearn you must drive as "NORMAL" as possible. I know at the dealer when I road test with customers and let them drive...yeeha!... they drive like they are late for work and the relearn learns just that. So drive "softly" and let the trans/TCU get used it. There is a very specific driving style of 0-25 , 0-45, 0-55- and then coast downs from 55-0, 45-0 and 25-0 so it will learn up and down shifts. It is all listed in the TSBs we get for most transmissions at my work. Try it and see what happens.
