Why does the impeller and turbine have vanes in opposite directions? There are several parts to a torque converter (TC): The housing it attached to directly to the engine. It spins at the same speed as the engine (obviously). Attached to the housing are the fins of the pump. The pump is a centrifugal type pump.
Aug 6, 2016 · There is an internal clutch that locks the converter when engaged by the torque converter clutch solenoid. Fluid pressure it routed through the input shaft into the converter clutch, which engages the clutch. If it is non electronic transmission it uses a pressure switch inside the transmission to engage the solenoid (gm calls it a tcc solenoid) at a given speed and current gear (gear is ...
Jun 16, 2020 · To make it simple, does this kit & a lockup TC work together to make the transmission "lockup"? Sorry for all the questions, just learning here. I did not notice the transmission has a no-lockup TC until over a year or two after the shop did the work. (its a project vehicle & I only recently drove it to a show, that's when I noticed the issue).
Sep 28, 2022 · What goes around that is a stator shaft, which is solid to the transmission. When this is inside the torque converter, fluid flows out between the two parts and into the torque converter. It then flows back into the transmission between the stator and the torque converter itself (the outer part which sticks into the transmission).
A torque converter is a fluid based device which transfers energy from the engine to the transmission. Unless otherwise modified, it is not engaged in the manner you suggest. An explanation is available here: How does a torque converter work? For improved efficiency, many manufacturers are providing locking torque converters.
Aug 17, 2016 · The torque converter locks when the engine rpm (impeller/housing speed of converter) and the transmission input shaft (turbine speed of converter) are roughly equal -- thereby improving efficiency for cruising, but also mitigating any torque multiplaction effect of the torque converter.
Mar 2, 2023 · Looking at the design, you can see the input shaft of the transmission goes all the way through the torque converter and sits in the front part where the turbine is. The splined part at the input shaft engages the turbine. The stator sits behind it (towards the transmission), which is attached to the TC shell. If this was done in reverse, stability would be sacrificed and the transmission ...
Mar 3, 2016 · This is a great question, and the answer lies here: Why doesn't the engine stall out when you come to a stop with an automatic transmission? And more information here: How does a torque converter work. With a manual transmission, you push in the clutch to disengage the transmission. With an automatic, that job is handled by the torque converter.
Dec 4, 2015 · In other words, stall speed is the engine RPM at which the torque converter transfers the power of the engine to the transmission. A vehicle's engine is designed with a certain torque/power band so that, along with the transmission, the engine will be allowed to operate within that torque band to allow the vehicle to move.
Aug 2, 2015 · 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. Internally, depending on how the pump, stator, or turbine blades are affixed ...
