I'm a new member, I bought a 96 2DR Chevy Tahoe it's a 4X4 and I'm having trans problems I took it to a shop so that they can check the computer and 2 codes came up at the moment I don't have the codes but the guy say it's the trans the person I bought it from had just changed it, I've been driving the truck for a week now and just 2 days ago everytime I step on the gas pedal the truck was forcing itself....
