How do you make ecm think its in first and second using a th350 tran

[jetmech]

I have a th350 trans and use the traslator + w/ extender chip. To use the chip timing features i need the ecm to think its in first and second. Now it thinks its in 3rd and 4th all the time. Is there a way w/ the wiring to make the ecm go to first and second.

I talked w/ David Husek of turbo buick performance transmissions today and he staightened me out. Just a Chris said, ground pins b and c and the 3rd and 4th gear lights on direct scan should go out making the ecm think its back in first. Thanks
