Re: 2000 Trailblazer hard shifting and no torque converter lockup

kphilbin, the component that slips is usually the torque converter. In the valve body the TCC apply piston wears on the body itself allowing quite a bit of the apply pressure to leak by. There are a couple companies making kits to repair this without replacing the vavle body(GM's fix). I think the companies are transgo and Superior transmission, not real sure
