A Short Guide to Common Automatic Transmission Problems and Solutions
Automatic transmissions are complex mechanical systems that play a crucial role in the operation of modern vehicles. However, like any mechanical component, they are susceptible to various issues that can affect their performance and reliability. In this guide, we will explore some of the most common automatic transmission problems and solutions for addressing them.
Common Transmission Issues Orangevale
Slipping Transmission
A slipping transmission happens when your car suddenly changes gear or feels like it “slips” out of gear when you’re driving. This is one of the major automatic transmission issues, where you might notice the engine revving without any increase in speed or delay before the next gear changes. This issue can make driving dangerous if not addressed at the earliest.
Causes
- Faulty solenoids or pressure control valves
- Worn or damaged transmission bands or clutches
- Low transmission fluid levels or dirty/contaminated fluid
Solutions
- Test and replace faulty solenoids or pressure control valves.
- Inspect and replace worn transmission bands or clutches as needed.
- Check transmission fluid level and condition. If low or dirty, perform a transmission fluid flush and refill.
Transmission Fluid Leaks
Transmission fluid leak problems can occur due to worn seals, gaskets, or damaged transmission pans. It can happen to both manual and automatic transmissions. If you see red or brown fluid under your vehicle - that’s usually when your transmission fluid is leaking out. If left unchecked, leaks can cause low fluid levels - which leads to overheating and internal damage.
Causes
- Worn or damaged transmission seals or gaskets
- Faulty torque converter seal or input/output shaft seals
- Loose transmission pan bolts or damaged transmission pan
Solutions
- Inspect and replace faulty torque converter seals or input/output shaft seals
- Locate and repair the source of the leak by replacing worn seals or gaskets
- Tighten loose transmission pan bolts or replace the transmission pan if damaged.
Delayed Or Harsh Shifting
Delayed or harsh shifting occurs when the transmission doesn’t change gears smoothly or takes too long to shift. You might feel a jolt when accelerating or decelerating or notice the car hesitating before moving into the next gear. These problems are generally common in automatic transmission - especially if you have vehicles with electronic control systems.
Causes
- Worn or damaged shift solenoids or valve body
- Low transmission fluid levels or dirty/contaminated fluid
- Transmission control module (TCM) issues or software glitches
Solutions
- Test and diagnose TCM issues and reprogram or replace as needed
- Inspect and replace worn or faulty shift solenoids or valve body components
- Check transmission fluid level and condition. Perform a fluid flush and refill if necessary
Torque Converter Problem
Torque converter problems can manifest as overheating, slipping, or unusual noises coming from the transmission. Torque problems are an important part of an automatic transmission, which transfers engine power to the transmission - so that your vehicle can stop without stalling.
Causes
- Torque converter lock-up solenoid issues
- Worn or damaged torque converter clutch
- Fluid contamination or debris in the torque converter
Solutions
- Test and replace the faulty torque converter lock-up solenoid
- Inspect and replace the torque converter clutch if worn or damaged
- Perform a thorough transmission flush to remove any contaminants or debris.
Worn Clutch
A work clutch is one of the major manual transmission problems drivers face. The clutch connects and disconnects the engine from the transmission so you can change gears smoothly. Over time, with frequent stop-and-go driving - the clutch disc can wear down and start to slip or feel spongy. This affects the car’s ability to shift properly and reduces overall performance.
Causes
- Riding the clutch (keeping your foot on the pedal for too long)
- Normal wear and tear from high mileage or frequent gear shifting
- Aggressive driving or towing heavy loads with a manual transmission
Solutions
- Inspect the clutch system for wear or damage
- Replace the clutch disc, pressure plate, or release bearing if needed
- Advise on proper driving techniques to extend clutch life and avoid premature wear
Delayed Or Harsh Shifting
Delayed or harsh shifting occurs when the transmission doesn’t change gears smoothly or takes too long to shift. You might feel a jolt when accelerating or decelerating or notice the car hesitating before moving into the next gear. These problems are generally common in automatic transmission - especially if you have vehicles with electronic control systems.
Causes
- Worn or damaged shift solenoids or valve body
- Low transmission fluid levels or dirty/contaminated fluid
- Transmission control module (TCM) issues or software glitches
Solutions
- Test and diagnose TCM issues and reprogram or replace as needed
- Inspect and replace worn or faulty shift solenoids or valve body components
- Check transmission fluid level and condition. Perform a fluid flush and refill if necessary
