[nhorn1983]

i had to unhook abs sensor underhood cause everytime u go to take off not stop either traction or abs would surge on any ideas what needs to be fixed... next hard shifting and vibration on take off mount or something more.. also heater only blows hot out on 90 anything else its cold any ideas thanks

The abs should be scanned for codes and sensor inputs. The vibration on take off needs onsite road testing to pin that down( mounts, axles, misfire), the trans issue could be many things, engine tune, skewed tps, bad trans pressure control solenoid to name a few.

Blend door out of calibration, broken gear in actuator or, clogged heater core, stuck thermostat, poor coolant circulation, just to name a few.
