Frequently Asked Questions

  • Introduction

    Transmission repair technicians work in auto body shops and assist with broken transmission adjustments, new transmission installs, transmission resealing, and inspections. Vehicles often require transmission repair when they're leaking fluid, making grinding noises, or shaking. Most transmissions are designed to last between 80,000 and 150,000 miles.

    In certain vehicles, the check engine light may come on when there are transmission problems, and in most cases, transmissions don't completely go out without giving off warning signs. Minor transmission issues can often be remedied by flushing out the system or repairing small parts of the system, while more extensive matters may require complete replacement.
  • What is transmission repair?

    Transmission repair refers to multiple types of repairs performed on a vehicle's transmission. Repair options include fluid replacement, adjustments, resealing, leak repair, and complete transmission overhaul. In cases where transmissions have completely failed due to age or severe damage, full replacements are often required.

  • What are signs that your transmission is going out? 

    Signs that a transmission is going out can include fluid leakage, slow response or a total lack of response, grinding and jerking when driving, and a burning smell coming from the vehicle. A vehicle owner may also notice that their car doesn't easily go into gear, and the service engine soon light may come on more frequently.

  • What causes a transmission to go out?

    Transmissions can go out for a variety of reasons, including overheating, failure to maintain fluid levels, starting the vehicle too quickly, and abrupt stopping. In certain cases, using the wrong type of fluid can also lead to transmission failure.

  • Can you drive with a bad transmission?

    In certain cases, it's possible to drive with a bad transmission. However, depending on the extent of the damage, it can be risky and dangerous, and it's not recommended. When a transmission continually slips out of gear into neutral or it's continually leaking fluid, it should be assessed by a mechanic immediately.

  • Can you repair a transmission without replacing it?

    If only one specific part of a transmission requires repair, or if a transmission is simply in need of a tune-up or fluid replenishment, a full replacement may not be needed. Replacements are generally recommended when there is total transmission failure or vehicles have been driven between 80,000 and 150,000 miles.

  • Should I repair my transmission?

    When a transmission is leaking fluid or causing the vehicle to jerk or not start properly, it's important to consult with a skilled mechanic who can perform repairs to prevent further damage and potentially dangerous driving conditions. In certain cases, such as complete transmission failure, replacements or rebuilds are often recommended.
