TCC (torque converter clutch) 82' Cutlass

Is anyone familiar with the TCC solenoid for G.M.
How to de energize it to unlock the torque converter?

Tcc should unlock when throttle is at idle or brake is depressed. Other than that you can temporarly get it unlocked by unplugging the 4 wire connector on the trans. This is temporary as it WILL destroy the trans if you drive like thisnfor more than a short time/distance.

My 1994 Olds Cutlass Ciera had it's TCC unplugged, and it drove on for over 150,000 miles before the engine gave out...It won't destroy the transmission, but you'll notice your fuel milage will go down by about 10%-15%. My 93 Olds Cutlass Supreme had it's TCC unplugged at about 50,000 miles, and it's still going strong today with over 160,000 miles on it. Like I said you'll most likely notice a slight reduction in fuel milage.

Cory, this is true on the older GM cars like the ones you pointed out, but do not try it on any car newer than 97 or 98 with overdrive or it will destroy the trans. The TCC on these cars engages in third gear and in overdrive, and the fluid volume moving thru the cooler is reduced when the TCC is not locked causing extra heat to build in trans and cause damage. TCC is good for about 1 to 2 mpg at best, according to instructors at GMs training center, if it changed yours 10 to 15 percent i would be looking for other troubles such as a slipping torqur converter, or trans clutches.

But OP said it's an 82 Cutlass in the title box. That's why I pointed out that unplugging the TCC won't hurt the transmission. To OP as far as the TCC being stuck...hopefully someone else can help you with it not releasing.

Starduster: the only cure is to pull the trans and replace the converter.

Cory: I looked right over the title box.

It's an '82...I think it deserves a new trans by now...we're talking 26 years!
