Our highly trained specialists are standing by to make your car drive like new again.

    Adjustments and In-Car Repairs

    There are several problems that can be resolved with an adjustment (A simple adjustment is one that can be made without removing the transmission from the vehicle.) or minor repair.

    If a late model transmission (computer-controlled transmissions started becoming popular in the early ’90s) is not shifting properly, it is often the result of a computer sending incorrect signals due to a faulty sensor, or the transmission is not reacting to the computer command because of a bad connection or defective solenoid pack. These problems can be corrected while the transmission is in the car for considerably less money than a complete overhaul.

    If a non computer-controlled transmission is shifting too early or too late, it may require an adjustment to the throttle cable. Since throttle cables rarely go out of adjustment on their own or due to wear and tear, these mis-adjustments are usually due to other repair work or damage from an accident. If the vehicle has a vacuum modulator instead of a throttle cable, there is an adjustment that can be made using an adjustment screw in some modulator designs. In vehicles with modulators, however, it is very important that there are no vacuum leaks and the engine is running at peak efficiency. Engine vacuum is very sensitive to how well the engine is running. In fact, many technicians use a vacuum gauge to diagnose performance problems and state-of-tune. Many problems that seem to be transmission problems disappear after a tune-up or engine performance related repair was completed.

    In some older transmissions, bands can be adjusted to resolve ‘slipping’ conditions. Slipping is when an engine races briefly when the transmission shifts from one gear to the next. There are no adjustments for clutch packs however.

    Reseal Job

    A transmission is resealed in order to repair external transmission fluid leaks. If you see spots of red oil on the ground under the car, your transmission may be a candidate for a reseal job. In order to check a transmission for leaks, a technician will put the car on a lift and examine the unit for signs of oil leaks. If a leak is spotted at any of the external seals or gaskets and the transmission otherwise performs well, the technician will most likely recommend that the transmission be resealed.

    Most of the external seals can be replaced while the transmission is still in the car but, if the front seal must be replaced, the transmission must first be removed from the vehicle in order to gain access to it, making it a much costlier job.

    Replace Accessible Parts

    There are a number of parts that are accessible without requiring the removal of the complete transmission. Many of the control parts including most of the electrical parts are serviceable by simply removing the oil pan. The parts that are accessible, however, vary from transmission to transmission and most transmission repair facilities would hesitate to provide meaningful warranties on external repairs for the simple reason that they cannot see if there are any additional internal problems in the components that are only accessible by transmission removal.


    If your Check Engine, ABS or Air Bag light is on, don’t hesitate to bring your vehicle to Lil Pete's Automotive Inc and have one of our technicians perform the auto diagnostics to provide an honest estimate for repairs.

    A vehicle’s engine control unit has access to a variety of devices in the car—and this can often be taken for granted. An engine control unit will check the airbag, turning signals and other courtesy lights for consistency and functionality as well as monitor the temperature of your oil and other important readouts of the vehicle. Newer and more sophisticated vehicles may have up to 80 functions of the engine control unit. Every car has many functioning computers and as such, it may require a few diagnostic runs of this process to be able to catch everything.

    At Lil Pete's Automotive Inc, our diagnostic tools will provide readouts for a car tune up which will re-tune your vehicle to its original factory standards, check safety systems, and ensure that your vehicle is running at maximum performance. Here are a few examples of what the engine control unit typically controls:

    • Fuel Mixture – Fuel-injected vehicles have a carefully measured level of fuel and oxygen required for combustion. Without the proper fuel mixture, your car’s average fuel economy may be suffering, and your car may be running too hot or too cold.
    • Ignition Timing – This basically ensures that your spark plugs are firing at the correct time. Engine misfire is caused by the misfiring of spark plugs, which can lead to a knocking or pinging sound in your engine.
    • Idle Speed – This is a measurement of your engine’s Revolutions Per Minute (RPM) while at rest. If your car is equipped with a Full Authority Throttle Control, cruise control and top speed limitations are also controlled by the same system.
    • Variable Valve Timing – Some vehicles are equipped with certain valves that need to open and close at a specific time in the engine cycle. This will ensure the optimum economy and power of your engine.
    • Water Temperature Correction – When your engine is still cold, this will add just a bit more fuel into the engine and warm it up a little faster so your car can get to normal operating temperature.
    • Fuel Pressure Modifier – This increases the fuel injection fire time if your fuel pressure is abnormally low.

    For any issues or problems regarding car misfire, engine misfire, and car tune up, let the professionals at Lil Pete's Automotive Inc take care of it. A trusty auto mechanic shop can help guarantee safety for you and your passengers.

    Oil, Lube, & Filter

    Your vehicle relies on oil, lubrication and an oil filter to keep it running smoothly. Every three months or 3,000 miles, your vehicle should be ready for an oil change. At Lil Pete's Automotive Inc we offer full oil, lube and filter changes that include:

    • Changing the oil filter
    • Checking the air filter

    • Lubricating all fittings
    • Checking engine for leaks
    • Checking belts and hoses
    • Checking tire pressure
    • Checking entire undercarriage

    What’s the difference between Synthetic vs. Conventional Oil?

    The myth is that all synthetic oil is purely man-made and not based on oils found in nature. In today’s synthetic oils, crude or natural oil is purified and then structurally modified to produce improved performance.

    Today’s motor oils contain base oils and several additives that are carefully blended together. Synthetic base oils may be made from a variety of chemicals and processes that are designed to have excellent performance at extreme temperatures and operating conditions. Select additives are used to improve flow characteristics and lubricating quality in the harshest of conditions. Conventional base oils are refined from crude oil. Additives may also be carefully added to conventional base oils to make quality motor oils as well.

    While synthetic motor oils can provide exceptional performance and protection, they don’t eliminate the need for regular oil changes. High quality synthetic motor oils can perform and protect better than conventional motor oils, but engines running on gasoline or diesel will continue to naturally contaminate and stress the oil, and the additives can only work for so long.


    The brake system provides the ability to stop a vehicle efficiently and safely and therefore is a vital component of driving safely. A well maintained brake system protects the vehicle, driver, passengers and others sharing the road. Periodic inspection of friction material, vital system components and hydraulics helps to ensure efficient system performance and cost effective brake repair.

    What do we do?

    Lil Pete's Automotive Inc technicians begin with a thorough inspection of a vehicle’s brake linings and key components. A written evaluation, with detailed diagnoses of findings, is provided and reviewed with the customer. Brake service recommendations are based on the vehicle manufacturer’s specifications and the existing condition of brake components that impact system performance.

    How often?

    Vehicle manufacturers recommend brake repair inspection at regular intervals, usually every 12,000 miles, to ensure vehicle safety and cost effective repairs. Brake repair & services are recommended based on vehicle manufacturer specifications and existing conditions for brake linings and other key component.
