My point is if he is seeing 800RPM of slip when he is expecting it to lock, the TCM will inhibit it no matter what if it's stock tuning.

My point is anything above 400RPM difference between turbine/output ss things get iffy for converter clutch lock.

^yes ive got logs showing this with lmm(1056) the 1078 cures all of my lockup problems so far.



Weird thing is, I've got logs of the lb7 applying tcc with 900 rpm of slip!

No that was the difference between engine rom and turbine sensor! It locked the converter and difference went to 0

The 01 TCM OS can lock when slip exceeds 625 RPM's. They won't always do it, but I've had mine lock up pretty consistently with 700-800 RPM's of slip.
