My understanding is the transmission housing is weak on some of the Chevy trans and will crack allowing excessive clearances internally. I test drove a blazer with a similar problem. Under light load it was ok, but put any stress on the drivetrain and it would pop and grind with no acceleration. My tech said it would require at the very least a rebuild with a possible case replacement.
maybe did she have a slight spot on her sweat shorts and underwear
The break pad.
No! Something is wrong.
Get the codes read at a dealership or local garage. Sounds like it could be a spark plug or a coil. Neither is an expensive fix but if it happens to be one of the back four cylinders its not the easiest thing to change.
When you're brake pads be calm worn, they will have a slight shimmy when you apply the brakes. When the brake pads are completely worn out they will make a grinding noise.
Grinding noise is metal to metal contact between the brake pads and brake rotor or break shoe and brake drum. Prolonged contact between metal to metal can result in front or rear brake failure.
It could be as simple as a slight imperfection in one of the gears or it could be an indication that the drive shaft or "half shaft" is worn.
There is a slight difference. A thrust fault is a variety of reverse fault with a dip angle of less than 45 degrees.
Sounds like bad wheel bearings Also check transmission output shaft bearing and u joints
Answer Quite probably you have a bad ground or a short in your wiring harness. You could always go to a garage which checks the wiring instead of a regular garage who uses the process of trial by elimination.
In automatic transmissions, there is constant pressure form the pump at idle. This means that when going from Neutral to reverse, that pressure is suddenly slammed onto the drive train of the vehicle, if the engine doesn't stall. This gives the slight jerk/movement.
By applying slight pressure to a tooth, the bone on the forward side will reabsorb, while the bone on the reverse side will be reformed
