Causes Behind A Slipping Transmission
There are several causes behind a slipping transmission, and it’s important to identify the root cause to effectively fix the problem. Here are some common causes of transmission slipping:
Low transmission fluid levels
Low transmission fluid levels are one of the most common causes of slipping transmission. The transmission fluid serves as a lubricant, coolant, and hydraulic fluid in the transmission system. It helps the transmission to shift gears smoothly, cool down the internal components, and transfer power from the engine to the wheels. Without enough fluid, the transmission can’t operate at its optimal level, leading to slipping, grinding, or jerking.
Worn-out clutch plates
In manual transmissions, the clutch is responsible for engaging and disengaging the gears. Over time, the clutch plates can wear out, causing the transmission to slip. If you notice that the clutch pedal is not engaging properly, it’s time to get it checked by a mechanic.
Faulty solenoid
Solenoids are responsible for controlling the flow of fluid in the transmission system. A faulty solenoid can cause a lack of pressure, leading to slipping. A mechanic can diagnose the issue and replace the faulty solenoid.
Burnt transmission fluid
Over time, transmission fluid can break down and become burnt, causing it to lose its lubricating properties. This can lead to slipping and other transmission issues. Regular fluid changes can prevent this problem.
Worn-out bands
Automatic transmissions rely on bands to control the gears and transfer power from the engine to the wheels. The bands, made of metal or friction material, are wrapped around drums or gears and controlled by hydraulic pressure. As the transmission shifts gears, the bands tighten to lock the desired gear in place. Over time, the bands can wear out due to regular use, age, or other factors. Worn-out bands can cause slipping, jerking, or difficulty shifting.
Faulty torque converter
The torque converter transfers power from the engine to the transmission. A faulty torque converter can cause slipping and other transmission issues. A mechanic can diagnose the issue and replace the faulty torque converter.
Mechanical components
One common cause of mechanical damage to the transmission system is the failure of the clutch system. The clutch is responsible for engaging and disengaging the transmission system from the engine, allowing the vehicle to shift gears smoothly. Over time, the clutch can become worn and require replacement. When the clutch is worn-out, it can cause the transmission to slip, making it difficult to shift gears and affecting the vehicle’s performance.
Identifying the cause of a slipping transmission is essential to fixing the issue. If you notice any signs of slipping, such as delayed or erratic shifts, unusual noises, or a burning smell, it’s essential to take your vehicle to a mechanic for diagnosis and repair. Ignoring the issue can lead to further damage and costly repairs.

Is it cheaper to repair or replace a transmission?
In general, it is usually cheaper to repair a transmission than to replace it. When repairing a transmission, only the faulty components are replaced, so the cost can be significantly lower than a full transmission replacement.
However, the cost of the repair will depend on the extent of the damage and the specific parts that need to be replaced. In some cases, a transmission may be so damaged that a complete replacement is necessary.
What does a transmission slip feel like?
When a transmission slips, you may feel like your car is changing gears without any input from you, or it may struggle to accelerate and feel like it’s lacking power. You might also experience a delay in acceleration or notice that the engine is making a high-pitched whining noise. Additionally, you may feel like the car is shaking or vibrating while driving, especially at higher speeds.
What sensor can cause a transmission to slip?
The sensor that can cause a transmission to slip is the Transmission Speed Sensor (TSS), also known as the Turbine Speed Sensor (TSS). This sensor provides crucial information to the Powertrain Control Module (PCM) about the speed of the input and output shafts of the transmission. The PCM uses this information to determine the proper gear ratio and when to shift gears. If the TSS fails, the PCM won’t receive the necessary information, and this can lead to shifting problems, including slipping, delayed shifting, or harsh shifting.
Will changing transmission fluid help shifting?
Changing the transmission fluid can indeed help with shifting issues. Over time, transmission fluid can break down and become contaminated with dirt and debris, which can cause it to lose its effectiveness at lubricating and cooling the transmission. This can lead to sluggish or delayed shifting, as well as other transmission problems. Manufacturers recommend changing the transmission fluid every 150,000 miles under normal conditions. If you’re experiencing shifting issues, a fluid change may solve the problem and help restore smooth shifts.
It is not recommended to drive with a bad transmission because it can be unsafe and potentially cause further damage to the vehicle. It is best to have the transmission diagnosed and repaired as soon as possible by a qualified mechanic. Driving with a bad transmission can lead to difficulties shifting gears, loss of power, unusual noises, and other safety issues on the road.
Will your car still run if your transmission is gone?
Yes, your car may still run if your transmission is slipping or has some issues, but it may not be drivable.
