It serves as a mechanical clutch, by separating the load from the power source. Want a Custom Built Performance Transmission? I think you should let a mechanic take a look with a Mercedes diagnostic tool, in this case, to test out all the maneuvers of the transmission with the tool. If you hear any noises, lift up the car and see if there could be other things that are causing the noises before replacing the transmission torque converter. Lean on the gas and stator speed falls behind and torque multiplication comes into play, which is when you feel gut acceleration. There are three main parts in a torque converter. The line coming out of the passenger side of the atf cooler is the pressure side and fluid will pump out of it from your transmission. This transmission is of a medium duty design and can handle up to 350 foot-pounds of torque.
Are you looking for 6R75 transmission troubleshooting help, 6R75 rebuilding tips, 6R75 technical service bulletins, 6R75 diagnostics or technical information? Any time you step on the gas, stator speed slows momentarily to help direct fluid and multiply torque. It is also dependent upon the machine's design. If you are feeling that your idle is a bit jumpy and sometimes too low and sometimes too high, it could be a problem with the torque converter. To diagnose it properly and visually inspect it you have to remove the transmission from the car and the engine. Because the impeller is mounted to the torque converter housing, and the converter is connected to the engine, the impeller gets its power from the engine. I am a mechanical engineer and yes it is true out of experience that if your car transmission oil was never replaced and the car has a lot of miles on it i would say 100K+ , is better not to change it, especially with ford based car.
It is a significant part of all heavy vehicles, marine propulsion systems, and industrial power transmission systems. Now, there is hardly any torque multiplication. I then cut off the excess. The turbine is connected to the output shaft, which sends power to the transmission. You want the torque converter to take hold stall at 2,400 to 2,600 rpm as the engine begins to make power. It only takes a little bending to put this rig into the hole seating it with the washer. At 5,200 rpm, the engine speed drops by 3,500 rpm with each upshift.
The stator is another series of fins located between the two turbines on the transmission shaft. Torque converter problems can be misinterpreted as symptoms of a failing transmission. The torque converter should move the car forward with a just a slightly tap on the acceleration pedal. Unfortunately the same thing happened to me as Pam — the dipstick broke off as I was removing it into the pan! Although this transmission uses cutting edge technology 6R75 problems can be a common occurrence especially when extended time lapses between maintenance intervals. Now, do I have a 4 speed? Anyone who knows for sure please let me know.
Another area for potential failure lies within the solenoids found inside the valve body. One way to do this is to use a device that physically connects and disconnects the engine and the transmission — a clutch. As a car buyer, i would want to know how the transmission oil smells before i buy a car. Faulty Torque Converter Clutch Solenoid The torque converter clutch solenoid is a common part to fail inside the automatic transmission. How does a torque converter work? I then used the dipstick as a measuring tool and cut a ring in the tubing at the proper fill line. Here is a table of the most known transmission colors and the condition: Color Condition Dark Brown Worn out - Replace the fluid Brown Slightly Burned - Replace the fluid Dark Red Okay Condition Pink Water mixed with the fluid Red Good Condition How to test a Torque Converter There are not a lot of things you can do to test the torque converter without taking it apart.
This 6 speed automatic was built for use in a wide variety of Ford vehicles. If the fluid were allowed to hit the pump, it would slow the engine down, wasting power. It can cause the converter housing to burst or rupture. I read old transmission fluid could be the cause or the spark plugs not ready for that headache yet. Stator and Clutch Stall speed is determined mostly by stator design.
Ive always opened a line to the cooler and had the tranny pump out the fluid on my other vehicles. Strange sounds are always a sign of something troublesome… Any weird sounds such as clicking, revving, clunking, or whining indicate possible problems with the torque converter — or the transmission. If you are installing your transmission that was purchased from Monster Transmission, our sales and support staff is here. It has just turned 90K. We suggest asking any specific questions through our Ask a Mechanic feature , and a real mechanic can get back to you soon. Turn one fan on, and it will blow air over the blades of the second fan, causing it to spin.
During acceleration, the stator turns at a slower speed than the impeller and turbine, which directs fluid flow more aggressively against the turbine blades. Drive around a bit til operating temp and check your level via the above noted dipstick and add or subtract as needed to get to proper level. This why you might experience shaking or shuddering when something goes wrong with the torque converter. For every 20 degrees you go over 200 degrees, you risk the chance of cutting the lifespan of the transmission by a factor of two. Before removing the driveshaft, drain the fluid from the transmission.
This is often why older transmissions are having a higher fuel consumption than a manual gearbox car. This is why a torque converter has a stator. The is the place where the industries best transmission rebuilders work together to help solve the most complex automatic transmission problems. If you can find metal pieces you do most likely have worn out torque converter bearings. Automatic transmission cars use a torque converter. This costs you precious time on the quarter-mile or at the traffic light. It should work for you Mustang owners, too! The engine needs to be connected to the rear wheels so the vehicle will move, and disconnected so the engine can continue to run when the vehicle is stopped.
