TCC switch & questions.....

[Mark Romans]

Do what GM does (As well as others) and retard the timing when the trans
shifts and when the tcc locks.  GM calls it torque management.

what you said.  Think I'll drop the TCC lockup, as this vehicle's my daily
transportation, not a race machine.

killing the engine for maybe 50msec, whilst the TCC's locking up?  Might be
pretty hard to time accurately, but the clutch would essentially lock under
no active engine load; there'd still be the inertia of the converter and a
speed mismatch between the engine crankshaft & trans input shaft, but should
be a lot easier on all components involved.  Probably not worth the effort
ITO lower ETs, but would ease the situation, even w/ the factory applied
lockup in 4th gear.
