A delayed, jerky automatic in an MX-5 IV often points to fluid condition, pressure control, or sensor/TCM issues.
Here’s how to narrow it down and when to stop driving.
What you're describing
If your fourth-generation MX-5 with the SkyActiv-Drive automatic feels like it pauses, flares, or thumps into the next gear, that's a real symptom worth taking seriously. In many cases it starts as a pressure-control, fluid, or adaptation issue long before the gearbox is actually worn out. The goal is to diagnose it early so a small repair doesn't become a very large one.
