My manual is on lone,
Memory, delays TC lockup cold weather
input for shift pressure
When overtemp detected,
Causes full pressure shifts, allows 3rd gear TCC lockup sooner, allows 2nd gear TCC lockup, Holds TCC lock up untill downshift ( no TCC unluck
before Downshift )
\\Above for 96 and later...

When working and getting od/lockup at 45 mph I detect no lugging. motor is smooth and response is instant.

I will install the fluid damper just because it is a better setup.
