Although not strictly a part of classic torque converter design, many automotive converters include a lock-up clutch to improve cruising power transmission efficiency and reduce heat. The application of the clutch locks the turbine to the impeller, causing all power transmission to be mechanical, thus eliminating losses associated with fluid drive.
This can become quite violent. Reasons for this part's failure: Piston stuck, or seals or springs damaged or missing. Correction for this problem: Check these parts for damage. Replace as required (located inside the transaxle, recommended that a transmission shop do the repair, but a full rebuild of the transaxle is NOT required).
There are also problems with the valve block and solenoids [citation needed] When this failure starts to occur, shift quality and speed, torque transfer and even loss of ability to engage gears can occur. These problems led Volkswagen Group to extend the warranty on all of their vehicles equipped with this transmission to 100,000 miles or 10 years.
On Mazda vehicles, this transmission uses Mazda M5 fluid (Mazda part number: 0000-77-112E-01), which is NOT Mercon V or Mercon LV according to Mazda Technical Service Bulletin 0500116. This fluid is made by Idemitsu Kosan (according to the label on the back of the Mazda bottle). Idemitsu sells the equivalent Type-M fluid in the aftermarket.
By historical context of comparison, the '50 Packard Ultramatic which was a torque converter applied two speed lock-up design with high and low range for four forward speeds and the '50 Studebaker/Detroit Gear featured a lock-up torque converter with three forward speeds. The lock-up feature of Packard's Ultramatic and Studebaker's DG 250 is ...
A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. [1] [2] Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable ...

The basis of the Turboglide's unique abilities was its five-element torque converter.Most automatic transmissions have a three-element torque converter, consisting of an impeller (an engine-driven pump); a turbine that rotates with the flywheel; a transmission-driven turbine that receives the energy of the oil propelled by the impeller, and a stator that redirects the recirculating oil so that ...
