  • What is the cost of a transmission check-up?

    Eagle Transmission offers free diagnostics and road tests for everyone!

  • How long does a transmission diagnostic take?

    Since we thoroughly assess your vehicle condition, a diagnostic usually ranges from 2 to 4 hours. Rest assured that everything will be tested to ensure that we can provide you with a comprehensive suggestion regarding the proper repair services that your transmission will need.

  • What is being done when my transmission is checked and scanned?

    During a transmission diagnostic, your vehicle will be connected to our system to thoroughly clarify the cause of the problem. Additionally, a physical check-up will also be done by our transmission experts to come up with a conclusive report regarding your vehicle's repair needs.

  • What is the cost for transmission fluid & filter change?

    There is no "one size fits all when it comes to transmission fluid & filter changes. At Eagle Transmission, a fluid & filter change may be as low as $89.95 depending on the year /make/model of your vehicle. Many of today's high-tech transmissions require special blends of fluids, some of which are manufacture specific. Synthetic transmission fluids are becoming more of the norm in many transmission applications. Many front-wheel drive vehicles require additional labor to access the filter as well. We provide our customers with transmission service that is specific to their vehicle, therefore, there may be considerable variation in the actual cost for a transmission fluid & filter service.

  • What is the average cost of repairing a transmission?

    There is no average cost to repair a transmission. Often there is a misconception between repairing a transmission and rebuilding a transmission. A typical transmission rebuild involves:


    • The removal of the unit
    • Complete disassembly Replacing all of the seals and gaskets Replacing any of the damaged bearings gears or drums
    • Replacing or rebuilding the valve body Replacing the solenoid packs as needed
    • Installing a reconditioned torque converter
    • Perform any factory suggested updates

    A transmission repair may be as simple as replacing external speed sensors at a much lower price than a complete transmission rebuild.

  • How long will it take to repair my transmission?

    The amount of time needed for transmission repairs and services depends on the severity of the condition. If itis just a usual fluid replacement, you need to leave your vehicle for approximately 2 hours.

Additionally, we will still road test your vehicle so as to be sure that it has been successfully done.
