Torque converter circuit

I hooked a code reader up to my 1999 olds silhouette van and it read P0742( torque converter circuit stuck on). What does this circuit consist of or does it just mean my coverter is shot.

There is a simple fix... you can unplug it ( a shop can do that in about 1 minute or less.)
It has to be taken apart(transmission) to install a new module.. Unplugging it will get rid of the OVERdrive function.. meaning a little higher RPM at highway speeds.. but will be cheaper than a 1500+$$ job of removal and repair....

1999 Buick Park Ave Ultra Service Engine Light Code #P0742


The code PO742 indicates the torque converter clutch is stuck on.
The torque converter is what connects the engine to the transmission.
It engages and disengages according to signals from the pcm, to aid in
smooth shifting. There are a couple of things you can try. make sure trans. fluid is full, if thats ok check the 20 pin connector, located on left
side of car on top of transmission bell housing. Make sure there's no
corrosion or bent pins. If this clears the code your all set, if not you may
want to ask your mechanic and see what he/she recomends.
Hope this helps.
Good luck
