A DIY Guide to Transmission Auto Repair Steps

Your car's transmission lies at the heart of its drivetrain system, and it is responsible for transmitting power from the engine to the wheels. However, just like any other part of your car, the transmission sometimes needs repairs. While a professional auto mechanic may handle the more complex transmission issues, some problems can be fixed DIY-style.

This blog will guide you through some of the critical transmission auto repair steps.

1) Diagnostic Testing

Before you commence any transmission repair, it's essential to pinpoint the problem correctly. Testing and diagnosing transmission issues can be quite tricky, so you may want to seek help from a professional mechanic if you do not have the necessary equipment or experience. However, if you have, you can use a code reader or scanner tool to read the diagnostic trouble codes (DTCs) from the onboard computer system and determine the issue.

2) Prepare the Work Area

Transmission repair is a messy process, and transmissions are notoriously heavy. Ensure you prepare a space with a level surface, ample room to work, a sturdy jack and jack stands, and a drain pan. You'll need the jack and stands to elevate the car and place it on level ground and the drain pan to catch the transmission fluid when you need to remove it.

3) Remove the Transmission Pan

Typically, when you have to fix any transmission issues, the first step is to remove the transmission pan. The pan holds the transmission fluid, and it's where you'll find the filter. Here, you'll need to consult the car's service manual on the appropriate tools and steps required to remove the pan. Ensure you have a drain pan to catch the transmission fluid that will spill out once you remove the pan.

4) Inspect the Filter and Gasket

Once you've removed the pan, inspect the filter and gasket. The filter could be clogged, and the gasket could be leaking. You should clean or replace the filter if it's clogged and replace the gasket if it's damaged or leaking. A damaged gasket could cause the transmission to lose fluid, leading to slippage and other problems.

5) Reassemble and Top Up

After you've made the necessary repairs or replacements, it's time to reassemble the parts, add transmission fluid, and test the vehicle with a road test. Start adding the fluid slowly and check the levels regularly. Ensure you test-drive your car to check for any issues such as slipping, gear issues, and poor shifting before calling it a day.

With the right tools, knowledge, and patience, you can manage to fix straightforward transmission faults. However, it's essential to know when to seek help from a professional mechanic. Transmission auto repair steps can be complex, and sometimes, even the slightest mistake can lead to significant issues. If you're not confident in your ability, seek professional help. Ensure you follow the manufacturer's recommendations regarding the timing of transmission fluid changes to avoid costly repairs in the future.
