TCI SSF 3500 lockup clutch I've had this converter in my bolt-on car for 7 months now. And the last few weeks it has started to not lock consistently. Like this morning on the way to work I was cruising at 50-55 MPH and it wouldn't lock. Then on the return trip home it performed flawlessly. Is is safe to assume that the thing is on its way out? What will happen if it totally fails?

It may be solved by tuning but you have to worry about the clutch disintegrating and taking out your tranny. I'd drop the pan and if there's no gunk in there, proceed to tuning.
I'd also recommend installing a Transgo shift kit which has a revised TC clutch valve that eliminates the PWM that will chew up your TCI clutch. I ran my TCI 3000 for three years and 24,000 miles with the Transgo and no issues.

Same problem with my old TCI SF3000. The clutch is
small and needs more pressure, zero slip learning and
bring the line up at lower throttle positions. If it slips
enough there'll be a slip-code set, it won't light the
SES light until a couple of times in a row but even
immature code will force a no-lock fault response
until next key-on. Then "all better" until the next
light uphill grade....
TCC min duty to 98%
TCC-locked base pressure increase or if not available
in your OS, up the 0%-commanded line by reducing
force motor current and taper it in smoothly for the
nearby columns.
