Can anyone explain TM?
I haven't seen a post on exactly how TM works. What does the computer actually do to control wheel spin? Does it vary according to perameters being read? Is it all computer controlled? Do all the newer Vettes have it, manual and auto tranny versions?

our throttle bodies are electronically controlled, not cable controlled like most vehicles. That allows the computer to close the throttle some. It also pulls ignition timing. Both reduce power.
Autos and manuals have it.

GM does not want to fix broken powertrain parts... so they limit the amount of torque at the tires (to around 280ish at 3000 rpmish I beleive)... So when the ECM senses this, it cut the power off, and adds tq more gradually...
There is NO way to delete it out of the stock ECM entirely, but you can set it to kick on so high that it never will. Mine is set at 6000 tq @ 6000 rpm.
Definately get rid of it, it becomes a whole new animal.

TC (traction control) is what controls rear wheel spin. TC can be turned off and on with the button on the center console. TM is a drive line saving program that is programmed and can not be simply controlled with a button. TM has to be edited with a tuning type software.
By the way there is a lot of mystery about exactly how TM works in the C6.

TM is there to stop some owners from "over" abusing the car which would likely cause serious damage to the power train (engine, trans, diff, etc.), and then come to GM looking for free repairs under warranty.
I think 99% of us wouldn't beat our cars as much as that, but some certainly would! It's not that TM is such a terrible thing, just some people would like to feel all the power the car has to offer without it being kept locked up and out of reach. At least we don't have speed limiters on our cars like so many other models do.

TM is more of a factor when you do not have wheel spin and torque begins to reach certain levels at the rear wheels. The computer will begin to reduce power to avoid the torque level.
