In some aspects, yes. A lockup converter is going to help at higher speed cruise that occurs below the converter stall. You enjoy better manners and lower temps here.

However the lockup converter strategy is always available to you and you may find the lower speed cruising in town still suffers from the same issues related to a loose converter.

My setup as an example uses a triple disc lockup converter. I can lock it up in 2nd through 4th gear at almost any rpm and throttle input. However the car drives better in the lower operating gears without being locked up. I use it instead in its performance application by locking it up at wide open throttle at about 4500 rpm in 3rd.

For cruise operation the converter locks only in 3rd and 4th at low throttle inputs and I have a fairly wide hysteresis set to keep the converter from cycling on and off. As a result a lot of in town driving does see lockup unless it’s a pretty steady state cruise.

For me this isn’t too terrible of a situation because even though the converter stalls around 3200 rpm, it is not incredibly loose and couples positively under that rpm when torque application is lower.

Mixed with a converter that is always very loose with a higher stall, the lockup is going to tend to be jerky as it engages.
