I'm new to the blazers and just bought one for my winter ride. It's a 2door 2001 4x4 has the 4.3 in it. It ran fine and good when I checked it all out. A week later it's like I'm driving on highway say 60mph and I feel a very very slight holdup like someone tapped the brakes. So I was reading about the tc lockup and when this happens if I hit the brakes my rpm jumps a few hundred rpms. I also noticed my abs light is on. Question is does this sound like a tc problem or maybe my abs? All incidents I read about the tc seemed severe to where there is bucking but mine is very very slight. U can barely notice it. Fluid is nice no smell.
