[Supras] Auto Trans Questions

[Christian, Skip]

Group,

	Has anyone had problems with their lock-up torque converters ??
Specifically, the lock-up feature stopping working after the trans fluid
gets really hot.  Also, every now and then, when pulling away from a
stop, the car starts moving OK, then feels like it has shifted into
third with lock-up on.  If I hold the gas down, it slowly accelerates,
then after about 10-15 seconds, feels like it down shifts to first with
no lock-up & goes great.  Kinda bizarre.....
	Is it possible to tighten up the torque converter mounting bolts
and/or flex plate bolts with out removing the transmission ?  Sorry to
ask this, but haven't looked to see if there's an access plate :-)
	Finally, with the engine off, if the lock-up was stuck on, with
the trans in Park, would this prevent me being able to turn the engine
over using a breaker bar on the crank pulley bolt ?

Thanks, Skip
