My Automatic Transmission Won#039;t Shift Into 2nd Gear

1. Check your transmission fluid levels first. Many times low fluid levels can adversely affect automatic transmission function and result in all kinds of performance issues, including the inability to shift into second gear. If your levels are good, move to the next step.
2. Reset your computer system. Resetting your car's onboard computer system can sometimes fix a programming issue and return your transmission to working order. Disconnect the battery completely and leave it off for 30 minutes. Reconnect the battery and allow the car five minutes to reset. Test the car by driving through the gears.
3. Bring your car to a licensed mechanic for a computer diagnostics test. If your car is a late-model vehicle with a computerized transmission, your best course of action may be to have a diagnostics test done at your local service station. The computer may have to be reset to return transmission performance to normal. The problem may not be mechanical at all.
4. Adjust or replace your throttle cables. If your car is not computerized, the problem may lie with a faulty throttle cable preventing timely shifting or any shifting at all. If your car has vacuum modulators instead of throttle cables, an adjustment could also help the situation.
5. Have a transmission diagnostic test done at your local transmission specialist. If all else fails bring it to the experts. Your problem may be a gear issue or a throttle body failure which will both have to be taken care of by a professional.

How to Replace Motor Mounts On a Mercedes Benz

1. Pop the hood of your Mercedes Benz to inspect the motor mounts. Common causes of malfunction include loose or fractured mounts. Reference the service manual for your model of Mercedes Benz for more specific instructions on locating the motor mounts. If the mounts are simply loose, you may only need to tighten them.
2. Set up a hydraulic jack underneath the engine of your car. Lift the engine of your Mercedes Benz with the jack until the stress has been removed from the motor mounts.
3. Check the flexible joint on your Mercedes Benz motor mounts for operational quality. Joints on motor mounts may become inflexible over time, reducing the mounts' ability to secure the engine without transferring physical shock while the vehicle is in motion. With the pressure relieved from the mounts, you can check the flexibility of each motor mount's rubber-coated joint with a screwdriver. Use your screwdriver to poke the rubber coating on the motor mount and note if the coating has any give to it. If the rubber is inflexible, the mount must be replaced.
4. Remove the motor mounts from your Mercedes Benz. Use a socket wrench and an appropriately-sized bit to remove the bolt securing the mounts to both the engine and other fixtures in the car hood. Some mounts can be removed through the top of the hood while others may need to be removed from underneath due to fixtures blocking the mounts from above.
5. Install your replacement motor mounts into the car hood of your Mercedes Benz. Mounting bolts will be included in the replacement motor mount packaging. Secure the motor mounts by tightening bolts in the appropriate locations with your socket wrench and wrench bit.
6. Release the hydraulic jack slowly to lower the engine of your Mercedes Benz. Close the car hood.

How to Change the Brake Pads on a BMW 328

1. Loosen the lug nuts that hold the BMW's wheels on with a lug wrench. Raise the vehicle with a floor jack and lower it onto jack stands at all four corners. Finish removing the lug nuts and the wheels and set them out of the way.
2. Spray brake cleaner on the brakes at all four corners of the vehicle and wipe everything down with a clean, dry rag.
3. On the front driver's side, remove the pad-wear cable from the retaining clip. Remove the plastic covers on the caliper guide bolts, located on the side facing the wheel well on the top and bottom of the caliper.
4. Loosen the upper and lower guide bolts with a 7 mm Allen wrench. Push the bolts out with a thin screwdriver and set them aside. Pry out the anti-rattle clip on the caliper with a screwdriver.
5. Slide the caliper assembly off the rotor. Support the caliper with a piece of wire tied to the suspension or with a platform so there is no weight on the brake line. Disconnect the wear sensor wire from the inner brake pad. Remove the brake pads.
6. Compress the caliper piston to make room for the new, thicker brake pads. Remove the lid on the brake fluid reservoir. Remove some of the brake fluid with a syringe so the fluid does not spill out of the reservoir. Use a wooden handle leveraged against the piston to push it into the caliper. You can also use an adjustable wrench or a C-clamp to press the piston in.
7. Install the new brake pads in the same orientation that the old pads were removed. The inner pad is installed by pressing the metal clip into the caliper piston. The outer pad slides into the slot in the caliper carrier. Reconnect the pad wear sensor.
8. Slide the caliper over the rotor and install the caliper retaining bolts, tightening them firmly. Reinstall the anti-rattle clip and the caps that go on the caliper bolts. Reattach the pad sensor cable to the clip. Move to the rear.
9. Release the parking brake. On the passenger side remove the brake pad wear sensor cable from the retaining clip. Remove the plastic covers on the caliper guide bolts, located on the side facing the wheel well, on the top and bottom of the caliper.
10. Loosen the upper and lower guide bolts with a 7 mm Allen wrench. Push the bolts out with a thin screwdriver and set them aside. Pry out the anti-rattle clip on the caliper with a screwdriver.
11. Slide the caliper assembly off the rotor. Support the caliper with a piece of wire tied to the suspension or with a platform so there is no weight on the brake line. Disconnect the wear sensor wire from the inner brake pad. Remove the brake pads. Compress the caliper piston using the same method as you did on the front.
12. Install the new brake pads in the same orientation that the old pads were removed. The inner pad is installed by pressing the metal clip into the caliper piston. The outer pad slides into the slot in the caliper carrier. Reconnect the pad wear sensor.
13. Slide the caliper over the rotor and install the caliper retaining bolts, tightening them firmly. Reinstall the anti-rattle clip and the caps that go on the caliper bolts. Reattach the pad sensor cable to the clip. Replace the wheels and lower the vehicle to the ground. Check the brake fluid level. Top it off if necessary.

6.
Tap the tip of the square shank, screw extractor on the hole using a hammer or screw in the tip of the screw removal bit, depending on the type of extractor you have.
7.
Place a socket of the correct size on the extractor head, or use a pair of vise grips pliers, and turn the oil pan bolt free by turning the extractor counterclockwise. If you have the screw-in type extractor, turn the extractor counterclockwise to lock the thread on the tip of the extractor over the stripped bolt and force the bolt out as you keep turning the extractor counterclockwise.
8. Dislodge the stripped bolt from the extractor with a pair of slip joint pliers.
Thread Shell Removal
9. Select a drill bit with a diameter slightly smaller as the bolt's diameter you need to extract.
10. Drill a hole on the bolt deep enough to reach the tip of the stripped bolt.
11. Tap the bolt's thread shell remaining using a hammer and a punch or similar tool to extract the rest of the bolt. Just make sure not to damage the transmission threads.
