Delica L300 Automatic Transmission Shifting Issues

[HarioSoko]

I'm having issues where if I am going up a slight hill or push my gas pedal even the slightest at high speeds, the transmission shifts into a lower gear. Like back and forth from 3rd to 4th but its rapid and unusual. I've changed the A/T transmission fluid already and checked its levels. Any other suggestions?

Check the transmission kick down cable and linkage at the injection pump and make sure the cable is in good condition.

Readjusted the kick-down cable and that fixed it. Thanks!!

Hi y’all! Experiencing similar issues. Any help or instructions on adjusting the linkage, kick down cable?

Note: previously it was getting into 4th after increasing rpms past 3500 but it was not smooth. Not sure if this is connected but the issue arose when switching overdrive off.


Here’s the linkage.
