Torque converter

We carry out repairs and complete recycling of torque converters for automatic transmissions for the following models and makes: Mercedes, BMW, Audi, Volkswagen and others. Repairs and recycling are done by replacing old parts with new original parts. We provide a warranty for the service we provide.

Diagnostics and glycol test for torque convetrers 

Diagnostics represent a glycol test, disassembly, inspection and cleaning of all components of the torque converter. Once the condition is established, we will get in touch with you. If the torque converter is in good condition, it is reassembled, then dynamically balanced and subjected to a test.

Repair and recycling of torque converters

Once the diagnostics are done, we proceed to the repair or recycling of the torque converter. Whether we are doing simple repairs or recycling, all parts will be replaced with new original ones. 

Even in the case of a non-defective torque converter, with the presence of glycol in the oil, all parts will be replaced as it would damage their structure and they would getting defected.

After replacing all parts, the torque converter is assembled and welded on a special machine, then dynamically balanced and subjected to a test. We provide a warranty for the service we provide.

What is a torque converter


A torque converter is a type of fluid coupling which transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load or transmission. It is usually located between the engine's flexplate and the transmission. The equivalent location in a manual transmission would be the mechanical clutch.

The key characteristic of a torque converter is its ability to multiply torque when the output rotational speed is so low that it allows the fluid coming off the curved vanes of the turbine to be deflected off the stator while it is locked against its one-way clutch, thus providing the equivalent of a reduction gear.

Some of these devices are also equipped with a "lockup" mechanism which rigidly binds the engine to the transmission when their speeds are nearly equal, to avoid slippage and a resulting loss of efficiency.

Typical problems of a torque converter

Symptoms of a defective torque converter include: overheating, slipping, shuddering, dirty fluid, high stall speeds or strange noises. In most cases, the torque converter will not be the cause of the problem, so do not rush to any conclusions until you have not checked first your automatic transmission.

Overheating- If you glance at your temperature gauge and it happens to be overheating, this could mean that your torque converter is malfunctioning. Overheating is probably the most common sign of torque converter problems, as a drop in fluid pressure will cause the transmission to overheat. It could also be a sign of low fluid levels or a malfunctioning solenoid.

Slipping - If not enough or too much fluid is passed to the transmission, it can cause gears to slip and you will often feel a loss of acceleration. You might also notice a sudden drop in your car’s fuel economy. Low or ineffective fluid can also be the culprit, so you need to check the fluid first if you experience any slipping.

Shuddering - If you start to feel shudders when driving about 50 to 80 km / h, this could mean that you have torque converter problems on your hand. It will often feel like running over rough road or bumps and you will definitely notice it when it happens. Shuddering comes and goes without warning, so once you feel it the first time you should get your transmission checked out as soon as possible. 

Contaminants in fluid - If you check the fluid and there are large amounts of black material, it either means your transmission or the torque converter clutches are damaged. You should perform a fluid change first, run your car for a while, and check back again.

Increased stall speed – A bad torque converter will take the transmission longer to engage the engine, resulting in higher than normal stall speeds. You can do a stall speed test to diagnose for any torque converter problems, but you’ll need to know your torque converter and engine’s stall speed specifications first.

Strange sounds – Any foreign sounds such as clicking or a revving noise could indicate a bad torque converter.
