Check your flex plate. Not real common but they are known to crack and sound like a engine knock or clicking. Considerably more noticeable in reverse. Bell housing bolts are known to back out a bit causing binding at the converter. Best of luck to you.

I have a 2012 Silverado 4WD. I just bought the truck in January with 30,000 miles on it. Within a week the torque converter needed to be replaced. Chevy replaced and another 12 days later had to repair again due to a bad seal in the converter. I am now hearing a whining noise coming from where the transfer case is, right next to my shifter on the floor. The noise will not start happening until the truck is warmed up and moving for 20-30 minutes. The noise is faint, at first I thought it was wind noise until I realized where it was coming from. The quicker I go, the quicker the noise, as I slow down it slows down and is non-existent at 20mph and below. Had it at the dealer 2x and they found nothing wrong. I asked about loose heat shield or something rubbing against the wheel or drive train issue and they say no. It only happens when the truck is moving and at a speed of 40 or more t really hear it. It goes away when I accelerate and is there only when I let off the gas. It will not make the sound in park or neutral. And if I drive the truck for an hour around town at 30mph I will 9 times out of 10 hear nothing, has to be driven at a higher speed for a bit for the noise to begin. This is driving me insane. I know how sounds travel through a vehicle so pinpointing is very difficult. Any suggestions?

If you can physically see where the leak is coming from, it may be best to have said component replaced. In this instance, it sounds as though you may have a crack in the reservoir tank, allowing coolant to drip out. If you are not 100% sure where the leak is coming from, it would be best to bring the vehicle to a mechanic for a proper diagnosis.

I have a 2005 Toyota Highlander with a 3.3L engine. There are no visible leaks, nothing is cracked or damaged, I replaced the radiator cap already, there is no coolant in the oil, oil level stays perfect, there is no sweet smell or dampness on the floor, however, I am using about a gallon of coolant every 2-3 weeks. It seems to go low faster if I need to accelerate more quickly. I have always maintained my fluids regularly do you have any idea where else the coolant could be going? Thanks

But clearly, Apple doesn't want to make devices with unbreakable screens, or it would. Consider this: What's a good motivator for people to upgrade to new phones? Something is wrong with the current model, as in, a cracked screen. Fix the glass issue, and Apple won't sell as many new ones.

A basic PCB consists of a flat sheet of insulating material and a layer of copper foil, laminated to the substrate. Chemical etching divides the copper into separate conducting lines called tracks or circuit traces, pads for connections, vias to pass connections between layers of copper, and features such as solid conductive areas for electromagnetic shielding or other purposes. The tracks function as wires fixed in place, and are insulated from each other by air and the board substrate material. The surface of a PCB may have a coating that protects the copper from corrosion and reduces the chances of solder shorts between traces or undesired electrical contact with stray bare wires. For its function in helping to prevent solder shorts, the coating is called solder resist or solder mask.

Each trace consists of a flat, narrow part of the copper foil that remains after etching. Its resistance, determined by its width, thickness, and length, must be sufficiently low for the current the conductor will carry. Power and ground traces may need to be wider than signal traces. In a multi-layer board one entire layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave circuits, transmission lines can be laid out in a planar form such as stripline or microstrip with carefully controlled dimensions to assure a consistent impedance. In radio-frequency and fast switching circuits the inductance and capacitance of the printed circuit board conductors become significant circuit elements, usually undesired; conversely, they can be used as a deliberate part of the circuit design, as in distributed-element filters, antennae, and fuses, obviating the need for additional discrete components. High density interconnects (HDI) PCBs have tracks and/or vias with a width or diameter of under 152 micrometers. [18]

Moisture absorption occurs when the material is exposed to high humidity or water. Both the resin and the reinforcement may absorb water; water also may be soaked by capillary forces through voids in the materials and along the reinforcement. Epoxies of the FR-4 materials are not too susceptible, with absorption of only 0.15%. Teflon has very low absorption of 0.01%. Polyimides and cyanate esters, on the other side, suffer from high water absorption. Absorbed water can lead to significant degradation of key parameters; it impairs tracking resistance, breakdown voltage, and dielectric parameters. Relative dielectric constant of water is about 73, compared to about 4 for common circuit board materials. Absorbed moisture can also vaporize on heating, as during soldering, and cause cracking and delamination,[20] the same effect responsible for "popcorning" damage on wet packaging of electronic parts. Careful baking of the substrates may be required to dry them prior to soldering.[21]
