How to Fix Car Transmission
1. Check the Transmission Fluid
The first step in fixing a car transmission is to check the transmission fluid. The transmission fluid is responsible for lubricating the gears and other components in the transmission. If the transmission fluid is low or dirty, it can cause the transmission to slip or shift hard. To check the transmission fluid, you will need to locate the transmission dipstick. The transmission dipstick is usually located on the side of the transmission or on the engine. Once you have located the dipstick, pull it out and check the fluid level. The fluid should be between the “full” and “add” marks on the dipstick. If the fluid is low, you will need to add more fluid. You can purchase transmission fluid at your local auto parts store.
2. Replace the Transmission Filter
If the transmission fluid is clean and at the correct level, the next step is to replace the transmission filter. The transmission filter is responsible for removing dirt and debris from the transmission fluid. A dirty transmission filter can cause the transmission to slip or shift hard. To replace the transmission filter, you will need to locate the transmission pan. The transmission pan is usually located on the bottom of the transmission. Once you have located the transmission pan, remove the bolts that hold it in place. Once the pan is removed, you will see the transmission filter. Remove the filter and replace it with a new one. You can purchase a transmission filter at your local auto parts store.
3. Adjust the Transmission Bands
If the transmission fluid and filter are clean, the next step is to adjust the transmission bands. The transmission bands are responsible for shifting the gears in the transmission. If the transmission bands are out of adjustment, it can cause the transmission to slip or shift hard. To adjust the transmission bands, you will need to locate the transmission adjustment screw. The transmission adjustment screw is usually located on the side of the transmission. Once you have located the adjustment screw, turn it clockwise to tighten the bands or counterclockwise to loosen the bands. You will need to adjust the bands until the transmission shifts smoothly.
4. Replace the Transmission Solenoids
If the transmission fluid, filter, and bands are all in good condition, the next step is to replace the transmission solenoids. The transmission solenoids are responsible for controlling the flow of fluid in the transmission. If the transmission solenoids are faulty, it can cause the transmission to slip or shift hard. To replace the transmission solenoids, you will need to locate the solenoid pack. The solenoid pack is usually located on the side of the transmission. Once you have located the solenoid pack, remove the bolts that hold it in place. Once the solenoid pack is removed, you will see the solenoids. Remove the solenoids and replace them with new ones. You can purchase transmission solenoids at your local auto parts store.
5. Rebuild or Replace the Transmission
If you have tried all of the above steps and the transmission is still not working properly, you may need to rebuild or replace the transmission. Rebuilding a transmission is a complex and time-consuming process. It is best to leave this job to a qualified mechanic. Replacing a transmission is also a complex and expensive process. However, it may be the only option if the transmission is severely damaged.
Conclusion
Fixing a car transmission can be a challenging task. However, by following the steps in this article, you can increase your chances of success. If you are not comfortable working on your own car, it is best to take it to a qualified mechanic.
