Hi everyone.
For the past year or so, I'm noticing that the shift from 2-3 under "normal" acceleration stutters/hesitates and seems to be much more noticeable than all other gear changes. All others are smooth as silk even when accelerating harder.
Mentioned to the good old dealer and they came back with no fault found.....
The hard shift is somewhat more noticable when the tranny/engine is cold. Reduces as the vehicle warms up.
Would appreciate any suggestions/directions.
Current mileage is 42,000 kms. Perhaps a tranny fluid change as a start?

Thanks in advance.

 

Going through that now, right after a torque converter replacement last week. They were stumped why it was shifting so hard, the tech was worried it would break!

They decided, finally, that it was the TCM, tranny control module. No codes, no indication other than really hard shifting. Then, they realized that the TCM was not "learning" or "adapting," which I guess figures heavily into its ongoing programming.

Change your fluid and be sure to drain and re-fill the torque converter separately. It has its own drain plug. If it stilll shifts hard, see if you can have any codes pulled and be looking at the TCM first.
