A damaged fin or bearing in the torque converter can cause hesitation in the transmission shifting, or the transmission to slip out of gear entirely. This is because the engine torque is not being efficiently converted into the hydraulic pressure needed to shift gears within the transmission.
Subsequently, one may also ask, can a bad torque converter cause no movement?
Much more so than a bad torque converter. No Vehicle Movement in Gear– This can also can happen with a bad torque converter, no movement in gear is more likely to a transmission problem if there is fluid in the case. Typically, a transmission with low fluid won’t provide movement because it’s not getting enough fluid.
Similarly, can you drive with a bad torque converter? Make sure to check first if you have enough high-quality fluid running in your car’s system. Another telltale sign of a faulty torque converter is dirty transmission fluid. Driving a car with a troublesome torque converter does not only exacerbate the problems already present, but it is also extremely dangerous.
Beside above, what are the signs of a bad torque converter?
Symptoms of Torque Converter Problems
- Slipping. A torque converter can slip out of gear or delay a shift its fin or bearing is damaged.
- Overheating.
- Contaminated Transmission Fluid.
- Shuddering.
- Increased Stall Speed.
- Unusual Sounds.
Can you replace a torque converter without replacing the transmission?
Transmissions when replaced will always come with a replacement torque converter along with them. You can never really flush a torque converter in the shop well enough to prevent contamination from an old converter from getting into a rebulit or new transmission. So, they come with one.

What happens when a torque converter fails?
If your torque converter can’t hold the proper amount of ATF, then it won’t be able to transfer power from the engine to the transmission effectively. This will result in overheating, shifting problems, strange noises, higher stall speeds, and slipping between the gears. The bad seal will need to be found and replaced.
How do you check a torque converter?
Testing for Bad Torque Converters Turn the ignition key and start up the engine. Wait for a few minutes for the engine to warm up, then gently press the accelerator twice and rev up the engine. Once it returns to its idle state, press the brake pedal all the way and shift into drive.
How do you remove a torque converter?
Remove the torque converter bolts one at a time with a 3/8-inch drive socket and ratchet. After removing one bolt, turn the crankshaft in the normal direction of rotation until the next bolt appears in the window of accessibility. Continue to turn the crankshaft until all three or four bolts are removed.
How do you flush a torque converter?
Flush the Torque Converter Start the vehicle. Place a funnel at the mouth of the transmission dipstick tube. Move the transmission through each of the gears when about three quarters of the total fluid capacity of the transmission has been drained and replaced.
What is a torque converter shudder?
The torque converter shudder is a brief shake in the vehicle whenever the internal clutches apply inside of the torque converter. They call this a lock up. Often this issue is misdiagnosed and sometimes will end up with the transmission needing to be rebuilt.
What does the inside of a torque converter look like?
The pump section of the torque converter is attached to the housing. The fluid then enters the blades of the turbine, which is connected to the transmission. The turbine causes the transmission to spin, which basically moves your car. You can see in the graphic below that the blades of the turbine are curved.
How does the torque converter work?
In brief, the torque converter is a type of fluid coupling, which allows the engine to spin somewhat independently of the transmission. It is responsible for pressurizing automatic transmission fluid, a pressurization that supplies the force necessary to shift transmission gears.
How much does it cost to fix a torque converter?
Most auto repair shops will charge someone anywhere from $600 to $1000 for a torque converter replacement job. If you would rather do the replacement job yourself, then a new torque converter will cost anywhere from $150 to $500. The exact cost depends on the make and model of your vehicle.
How long do torque converters last?
For newer cars, you should also have the transmission flushed every 40,000-50,000 miles or every 2 years, to remove all of the sediment and debris from the torque converter and cooler lines. Vehicles with manual transmissions should have the clutch fluid and gearbox oil changed every 30,000-40,000 miles.
How do I fix error code p0741?
What Repairs Will Fix P0741? Replace the torque converter clutch solenoid. Replace the torque converter or clutch. Change transmission fluid and filter. Repair/replace damaged wiring and connectors. Repair/replace TCM or ECU. Install a rebuilt or remanufactured transmission.
What is a high stall torque converter?
All “stall” means is if you mash the brake and gas at the same time, (or get on the trans brake), it allows the engine to rev up to “about” the stall RPM it’s rated at before it breaks the tires loose. You can buy a 3,500 RPM stall converter and not see 2,500 RPM of stall if your engine has no torque.
What happens if my torque converter goes out?
A malfunctioning torque converter can have a shudder that comes from the transmission. Its job is to smoothly convert engine torque into hydraulic pressure that your transmission uses to engage and shift gears. When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive.
Can a car run without a torque converter?
Without a torque converter, your automatic transmission won’t work. It allows a vehicle with an automatic transmission to come to a stop and not stall. A fluid coupling, or fluid hydrodynamic, allows the engine to spin independently of the transmission. This way the engine can keep running when the car is stopped.
How does transmission fluid get into the torque converter?
Torque converters transfer power by using an engine-mounted turbine to push oil (fluid) through a transmission-side turbine until that turbine can no longer pass fluid without moving. Unfortunately, many torque converters can only be refilled while the transmission is already out of the vehicle.
What is code p0741 mean?
When the code P0741 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is seeing greater than a 200 RPM difference between the rotational speed of the Torque Converter and the Transmission Input Shaft.
Why do torque converters fail?
A torque converter (TC) can fail in several different situations: Since TCs are made of metal, they are welded together. These welds can fail (split or break) due to excess pressure or by a poor welding job. This is most easily noticed leaking transmission fluid.
Will a torque converter fill itself?
The torque converter does not need to be primed to fill it. There is no pump inside the torque converter. The pump in the transmission is driven by the impeller side of the torque converter, which is bolted to the crankshaft.
