I inherited my dad's 1986 olds gutless sup brougham. I'm having trouble with the transmission. My dad wanted to keep it original bc it belonged to my mamaw and they bought it brand new. So when the engine wore out him and my uncle rebuilt it. They didn't however do anything to the transmission. And it went out. It has been setting for about 10 years and is in 100 % perfect shape except the transmission. It has no power and I'm not sure what I'm dealing with. It had the v8 and a 2004r in it. The over drive. I need some advice!
