my swap ( 2007 5.3 LMG/ 4L60E/BCM, underhood fusebox/'07 cluster and lots of the '07 harness into '97 Tahoe) is done, I had the first testdrives and only a few things have to be addressed.

1.) If've got the crank relaern DTC but couldn't perform a crank relearn with the latest EFIlive software. All signals are there ( P/N switch, brake applied..) but the bidirectional control seems not to start. When I don't press the brake the "press brake" message is displayed if I do so it disappears but nothing happens. Is there anything else I have to do? I went through some crank relearn threads but nothing new on this side..

2.) I have no tranny related DTC'S but the torque convertor clutch doesn't lock

3.) the engine seems to have reduced power. On the last third of the gas pedal nothing changes, also no downshifts appear

The only DTC'S I have are the crank relearn and the immobilizer key not programmed, that's all

Any ideas in these topics?
