Any idea as to what can cause the torque converter to act in this manner?

from your description, I could not tell if it was acting wrong, or not...

if it is locking and unlocking at a steady cruise with no pedal movement, then I would start with the switch that is activated by the brake pedal...make sure it is adjusted properly and that the brake pedal is not dropping down and pushing on the switch which is the unlock action


if you jump the aldl to lock the converter manually, does it stay locked then?

Thanks Steve.  My next step was to go your website.  Got too excited yesterday and instead of looking there, i posted here.  Never attemped to lock it manually though.  Was just posting my diagnosis.  I will go through your site and the proper procedure of finding the problem.  Thanks

If after following Steve's advice it still acts up while cruising - it may be an electrical issue (broken wire/intermittent connection) or a faulty torque converter solenoid - not too hard to fix, i had that issue many moons ago.

Lol. Many moons ago huh?  Lol.  I've always been afraid of dropping the transmission pan though.  Idk why. Guess i was always afraid of spilling all the fluids and stuff.
