After driving the car for 30 minutes or so it will not shift out of gear as you slow down for a stop and stalls out. Have to shift into neutral to keep engine running. If I shift back into drive while stopped t will stall out. Then can’t restart and put in gear without it stalling out. It’s stuck in a high gear. Is this the lock out clutch and can I disconnect it somehow?

There is a good chance the torque converter clutch is sticking in the applied mode as a result of a faulty torque converter clutch solenoid causing your 1995 Oldsmobile to stall after driving for 30 minutes. I would suspect that after letting the car sit for about 20 minutes it will start up and run fine. If you disconnect the solenoid chances are the check engine light will come on. The proper repair if indeed the solenoid is sticking would be to replace the failed solenoid and service the transmission.

This is a verry common problem.I had this same problem on my 95 cutlass.You can unplug the wiring at the bell housing and the converter will not lock up,but it will effect the fuel economy! The fix is if the brake lite switch is working and the switch for the converter lock up,cut off solenoid, is supplying voltage ,then the solenoid needs replaced.This is a pressure release switch located in the pan or cover on the back,side of the trans.You will need to remove the rear trans support and the cooler lines from the case,and all the bolts from the cover and the solenoid is just below the auxilary valve body.Not a bad job,but sure an improvement in driveability! And you can still expect 30 pluss mpg!
