Hello and welcome to JustAnswer!

What speed are you traveling when this happens?

It happens while coasting only?

Hi - It happens when the car is coming to a halt only. Ie, coming up to lights I'll slow down and about half a second before the car stops the car lurches and judders before stopping. It's almost like when driving a manual car and you forget to dip the clutch before stopping. It's not breaks as it happens when brakes are not applied.

If the engine is dragging down with the same feel as forgetting to press the clutch with a manual trans then the torque converter clutch is almost certainly coming on. This is often caused by the converter itself but on this trans the valve body was the most common cause. The fluid level should be checked also and it's also possible that there is damage to the filter, either way if the pump sucks air it can cause the converter clutch to lock.
