    93 Deville Converter lockout solenoid

    Hey everyone, I had a question for you all that has me stumped. I just bought a 93 deville for 2500, its a real clean car but when I have it in park, and kick the idle up to about 1000rpm it makes a pop crunch noise and comes out of park and rolls and then back into park again. The tranny shifts great, and when I run the idle up to about 650 or so and then let off the gas I can hear something makeing a scraping noise like something is spinning, like the torque converter trying to lock up when it is in park, so I think it might be the lockup torque converter clutch solenoid, if so is it in the valve body? Has anyone else ever heard of this problem with my type of caddy? Also the idle speed sensor is holding the idle up after I let off the gas pedal, anyone know anything about that? Your advice would be greatly appreciated. Jack

    I think its the parking pawl. It may have broken a tooth..... When it gets to the broken tooth it eventually slips and then moves to the next tooth......

    Im not sure though, you might be on to something for the TC......
