I don't even see a TCC related table that limits it to 758kpa.
2) Throttle follower, traction control, trans torque management and LINE PRESSURE. VTT's are extremely important for auto guys.
The shift pressure tables handle your shift pressures, but the VTT's effect how much line pressure you have when in gear as well as other obvious shift things like which row you're in for shift times/ pressures etc.
Also, the torque management role the VTT's effect us quite pronounced, for example with under reported torque, and 100% torque management requested, a lower amount of spark is pulled. Conversely, increase the VTT's still with 100% torque management allowed, and you will find alot more spark is pulled, in fact well into the negatives for the fast shifts if your ecm spark settings will let it go that low.Sorry for the confusion; I understand how TM and VTT work together. I am just wondering what other roles the VTT plays on this platform. From what I can tell, it is only taken into account when applying any form of Torque Management. On other platforms (newer models) it seems to do a lot more.
