[Diy_efi] Using GM '747 to control TCC lockup only -- THANKS!

[Rick McLeod]

If I understand the code correctly, the computer controlled lock-up attempts to control based on load, not just gear/rpm so it is really a electronic emulation of the old fashioned method.


Hi David,
I just happen to be a transmission specialist and yes, you need lock up 
unless you have really low (high numerically) rear gearing. I would 
recommend the vacuum setup as with proper adjustment it will 
automatically unlock under higher load conditions as it should. Hope 
this helps.
