07 Built trans TCC locks when WOT (T42)
I cant seem to get the trans to NOT lock up when WOT... It always locks somewhere right after 100 mph, the stall is NOT built to lock at WOT so this needs to be fixed. I've done all the tables like needed to be done, or am I missing something? Any help would be greatly appreciated! Here's the tune.

The Trailblazer SS is the same way, no matter how you set the tune it locks at stock speed no matter what. I am trying to do the opposite and get my converter to lock earlier @ WOT- I am told we are missing a couple of parameters and that they will be added someday, My fingers are crossed!
I just wanted to bump this. I'm in the same boat as Low03noma. I need my converter to lock sooner; it is killing my ET.
Im willing to pay extra for this at this point. LolOriginally Posted by JoshH
What year TBSS? If its an 06 or 07, Alvin at PCM4Less has a fix for you, give him a ring.

2013 Sonic RS Manual - 1.4L I4T E78, tuned, turbo mods, etc.
2008 TrailBlazer SS 3SS AWD Summit White - LS2 E67/T42, bolt ons, suspension, etc.
2002 Chevy TrailBlazer LT 4X4 Summit White - 4.2L I6 P10, lifted, wheels, etc.
Ive used the same method as Alvin on 06 trucks with great results and i also know how to make the converter stay locked when you let off the gas but it still doesnt let my 07 lockup early. Ive also tried his tcm in other trucks with the same result.
What is the fix that works for an 06? The T42 I'm trying to get to lockup is an 06 TCM.
I guess I'll just put a toggle switch to ground the TCC solenoid when I want it to lock. Maybe soon EFILive will get us the tables we need, and I can go back to letting the computer control it.
Ive been thinking of doing the same thing, just isnt going to be very consistent!
