5 Things To Look For When Transmission Slipping After Rebuild

Transmission slipping after rebuild is a common problem that occurs when the rebuild of an automatic transmission is not done correctly. It can occur for a variety of reasons, including incorrect assembly, incorrect fluid level, improper adjustment of the shift linkage, or worn parts. In some cases, it may be possible to fix the problem by adjusting the transmission linkage or replacing any worn parts. If the transmission slipping persists after making these adjustments, it may be necessary to remove and reinstall the transmission in order to properly diagnose and repair the issue.

Automobile: Transmission Slipping After a Rebuild


Common Symptoms



The most common symptom of transmission slipping after a rebuild is a feeling of slippage when the vehicle is under load. This can manifest in different ways, including an engine revving higher than normal when accelerating, or jerking when shifting gears. Other symptoms can include difficulty in shifting gears, or the transmission not engaging properly at all. In some cases, there may be an audible whine from the transmission that wasn’t present before the rebuild.

Diagnosing Transmission Slippage



To diagnose transmission slipping after a rebuild, it’s important to rule out other potential causes of slippage first. This could include checking for worn clutches, worn gears and bearing wear, as well as verifying correct hydraulic pressure in the system. It’s important to check for any leaks in the system as well. If these things have been ruled out and the transmission is still slipping, then it’s likely that there was an issue with either the rebuild process itself or with some component that was installed incorrectly during the rebuild process.

Clutch Issues



One potential cause of transmission slipping after a rebuild is an issue with one or more of the clutch components that were replaced during the rebuild process. If any of these components were installed incorrectly or are not compatible with your vehicle, then this can cause slippage when your vehicle is under load. It’s important to make sure that all new parts are compatible with your specific make and model before installation.

Gear Issues



Another potential cause of transmission slipping after a rebuild could be related to one or more of the gear components that were replaced during the process. If any of these components were not properly machined or installed correctly, then this can cause slippage when your vehicle is under load as well. It’s important to make sure all new parts are compatible and properly fitted before installation to avoid this issue.

Hydraulic Pressure Issues



Finally, another potential cause of transmission slipping after a rebuild could be related to incorrect hydraulic pressure in the system. If too much pressure is applied during operation, this can lead to slippage when your vehicle is under load due to excessive friction between moving parts in the system. It’s important to ensure proper hydraulic pressure levels are maintained throughout operation for best performance and reliability from your rebuilt transmission system.

Transmission Slipping After a Rebuild



The transmission is one of the most important components of an automobile. When it fails, it can cause a great deal of inconvenience and expense. Unfortunately, transmission slipping after a rebuild is a common problem faced by many drivers. Transmission slipping occurs when the vehicle is unable to maintain the correct gear ratio between engine speed and output shaft speed, causing the vehicle to move slower than its intended speed. This can be caused by several factors, including incorrect fluid levels, incorrect type of fluid, or an issue with the Electronic Control Unit (ECU). Fortunately, there are some steps that can be taken to prevent transmission slipping after a rebuild, as well as troubleshooting techniques to address any issues that may arise.

Prevention of Transmission Slipping After a Rebuild



The best way to prevent transmission slipping after a rebuild is through regular maintenance and check-ups. During these check-ups, make sure to inspect the fluid levels and type used in your vehicle’s transmission system. It’s important to use the correct type of fluid for your specific car model and make sure all the levels are kept within factory specifications. Additionally, make sure your car isn’t overheating while driving in order to avoid any issues with your transmission system.

Troubleshooting Transmission Slipping After a Rebuild



If you experience transmission slipping after rebuilding your vehicle’s transmission system, there are some troubleshooting techniques you can use in order to address the issue. First, adjust the clutch pedal free play if necessary; this should help reduce any slippage issues you may be experiencing with your transmission system. If this does not resolve the issue, then it may be necessary to examine any other parts of your transmission system that could be causing the problem. An experienced mechanic should be able to identify any parts that need replacing or repair in order to get your car back on track again.

FAQ & Answers



Q: What are the common symptoms of transmission slipping after a rebuild?
A: Common symptoms of transmission slipping after a rebuild include an inability to reach higher gears, a decrease in fuel efficiency, an increase in engine revs without an increase in speed, jerking when shifting gears and burning smells from the transmission.

Q: What causes transmission slipping after a rebuild?
A: After a rebuild, transmission slipping can be caused by clutch issues, gear issues, hydraulic pressure issues or electronic control unit issues.

Q: How can I prevent transmission slipping after a rebuild?
A: To prevent transmission slipping after a rebuild, ensure that the vehicle undergoes regular maintenance and check-ups, that the correct fluid levels and types are used and that the vehicle does not overheat.

Q: What should I do if my transmission is slipping?
A: If your transmission is slipping, you should adjust the clutch pedal free play. If this does not solve the problem then you may need to take your vehicle to an automotive repair shop for further investigation and repairs.

Q: What are some signs that my vehicle needs rebuilding?
A: Signs that your vehicle may need rebuilding include difficulty shifting gears or shifting between gears with a delay; noises such as whining or grinding when accelerating or decelerating; shaking when accelerating or decelerating; leaking fluids; burning smells; and decreased fuel efficiency.

In conclusion, it is important to understand that transmission slipping after a rebuild can be caused by a number of issues, such as a worn out clutch, low fluid levels, or a faulty torque converter. It is important to address these issues promptly in order to prevent further damage and ensure that your automobile is running smoothly and efficiently. However, it is also important to remember that transmission slipping can sometimes be caused by other more serious problems, such as mechanical issues within the transmission itself. Therefore, it is recommended to take your vehicle to a qualified automotive technician for diagnosis and repair if you experience any signs of transmission slipping after a rebuild.
