I'm trying to clarify the understanding of several parameters in the T43 controller. Specifically the 2012 6L90E logic. The questions are all over but thats just how my mind works..
For starters we have three modes to the end user;
1) Automatic Mode (selector in Drive)
2) Automatic Mode Sport (selector in S mode)
3) Manual Mode (using paddles) (TUTD)
Of course GM doesn't refer to these as such in the calibration so I'm trying to verify the following with respect to SHIFT PATTERN and rar
In this particular calibration we have;
1) NORMAL
2) PATTERN A
3) PATTERN B
Do they correspond as noted above?? Because these parameters below just make it more confusing...
{D7010} Shift Pattern A
{D7011} Shift Pattern B
{D8010} Pressure Pattern, Normal Select
{D8011} Pressure Pattern, Shift Pattern A Select
{D8012} Pressure Pattern, Shift Pattern B Select
{D8013} Pressure Pattern, TAP Up/Down Auto Select
{D8014} Pressure Pattern, TAP Up/Down Select
{D8015} Pressure Pattern, 4WD Low Select
D2216 for converter lock pressure ramp.....
This table will raise pressure to the TCC if it measures the noted rpm of slip. I assume that the rpm of slip is tied to TCC Desired slip tables? If so if you zero the Desired slip tables is D2216 still an active table?
Whats the difference with the WOT TCC lock up tables like say D2201 which has a row for 100 TPS (or WOT) and a paramater like D2225? Which one supercedes the other?
How does "self cleaning" work?? I see people have noted that it makes a difference to active through the DVT controls....
I have a TECH2 which we have used for years for doing FAST ADAPTIVE RELEARNS....every time I try and use that function with EFIL it doesnt work and it freezes the TCM and have no gears....a reflash fixes it....whats up with that?
I think its time to collectively assembly a TCM road map!
