2017 MKZ 2.0T Hard Shift

[dsn]

Just got this car, 94k miles. When shifting from 2nd to 3rd there is a very noticeable jump/jerk. It does not do this when accelerating lightly, but the harder I accelerate the worse the shift is. 

 

I figured just a transmission fluid change will fix this issue, but I'm curious if anyone else has had this issue

 

Thanks!

Hi dsn and welcome to the Lincoln MKZ Forum. Did you actually change the trans fluid or do you still need to change it? Definitely change it, if you have not already. However, be sure to use the proper specification replacement fluid, as outlined in your Owners Manual (see further below).

 

To answer your question: Yes, as with any vehicle, someone here will have had some sort of hard 2-3 shift, or 1-2 shift, or 3-4...etc. etc. But none of that will likely help you determine what the problem may be with your transmission.

 

If a full proper and professional transmission flush and fill does not help, you may need to have the transmission checked/reprogrammed etc etc.

 

You could also try disconnecting the battery in your MKZ (for at least 10 minutes), then follow the Idle Trim Relearn procedure outlined in your Owners Manual. It may help to clear the old TCM memory and correct the adaptive shift algorithms.

Hey thanks for getting back so soon, I haven't done the trans fluid change yet, but am going to in the next couple days and see if that fixes the issue. If not i'll check out the transmission reprogramming.
