Just got this off a forum for G-body:
*Re: 200 R4 Lockup problems*
------------------------------
All it takes is just a particle of debris to cause the internal valves or
solenoids to stick...Lockup solenoid staying energized (not likely),lockup
solenoid sticking (highly likely) or converter clutch apply valve sticking
(very likely), or few other very unlikely causes. Unplug the 4 pin connector
on drivers side of trans, take for short drive; if still locking up in
second, it is the solenoid sticking (serviceable from inside the pan) or the
apply valve (located in side of front pump assembly, the valve CAN be
serviced in car).
I am thinking the TCC apply valve could be the main culprit, because when I
take the power away, it still does not disengage. Is there a replacement
valve? Or is it just check balls and teflon seals?
More research is needed. Thinking out loud to the car crowd...
