Torque management Can someone please explain to me exactly what this is and how it works?
I did a search on this forum but didn't see anything really explaining this.
Reason I am ask is I plan to put a Vigilante or Yank converter in my car (01' SS).
I have heard this will cause problems with the tq. management and that it may need to be deleted from the PCM programming. I have also heard that doing so can cause premature failure of the trans. Is there a way to edit the tq. management so it does not create a problem and if so would a decent tuner know exactly what the settings would be or is it a trial and error type thing ?
thanks

I have played with this a lot and currently my scheme
leaves TM active, but just limits its authority to pull
out spark. This is a compromise that still applies -some-
power through the shifts (not total spark cut to -10
degrees but reduces it to +15 degrees advance) to give
the trans some input torque reduction and some measure
of protection.
I had mixed results from trying to be fancy with the
torque reduction percentage. Just capping off the spark
reduction seems to be straighter.

You want the cooler when you are generating a lot
of trans heat. Or just on general principles. But the
TM really only has to do with during the shift events.
Typically people put a cooler when they go to a new,
looser torque converter because that presents a
continuous higher heat shedding into the transmission
fluid.
A converter also tends to make the torque management
more obvious which is why you tend to see TM, converter
and cooler bundled together.
