torque converter slip actual vs desired

The logic of these schematics, which are not to scale and which have been greatly simplified for clarity, is that each color represents a set of components that are integral or otherwise connected so that they always rotate together; clutches, brake bands, planet pinions, and flywheels are shown in black or gray. The _gat cookie, which may appear as _gat_gtag_UA_6113964_2, was sometimes set along with the _ga and _gid cookies to control how frequently requests were sent to the Google Analytics servers; this cookie typically persisted for only a few minutes at a time. In order to get a realistic value, use: Your finish line MPH (from ET slip) Your finish line RPM. We thought 10 was bad 2 years ago. The Fora platform includes forum software by XenForo. Many aftermarket companies offer performance lockup torque converters that can provide a higher stall speed without sacrificing the advantages of the lockup converter for highway use. The payment button in the "Support Ate Up With Motor" box (and similar payment or donation buttons that may appear on portions of the administrative dashboard, which is not normally accessible except to logged-in administrative users) contains embedded content served by PayPal services. At stall speed, the impeller is spinning at engine rpm and the turbine is stopped. Some vehicles have a transmission temperature indicator that will let you know when your car's transmission is overheating. (For more information about our discontinuation of Google Analytics tracking on this website, see the "Online Tracking" section of the Privacy Policy. At idle and very low road speeds, slippage is desirable because it keeps the engine from stalling or lugging in gear. 4. Since the 1940s, automakers have come up with a variety of strategies for reducing or eliminating that slip, including series parallel split torque transmissions and different types of converter lockup clutches. The stator redirects fluid from the turbine to the impeller, radically increasing the force of the fluid entering the impeller and multiplying the torque input from the engine. After logging in, the wp-settings-UID cookies store the logged-in user's configuration settings, while the wp-settings-time-UID cookies record the time those configuration settings were last set; again, there may be multiple iterations of each of these cookies, which normally expire after about one year. 1. and 2. Many times, people think there is something wrong with their transmission when the problem lies with their torque converter. For people who want a broader overview, I would recommend a book by Philip G. Gott entitled Changing Gears: The Development of the Automotive Transmission, published by the SAE as part of their Historical Series in 1991. If governor pressure dropped below that threshold, the clutch would disengage. How To Log Transmission And Torque Converter Slip In HPtuners!!! For example, in park, it will say Desired Slip 1200, Actual: 730 (guess the engine rpm) As speed increases, the Desired Slip drops (don't remember exact numbers) as well as the actual. Off.).) Unless you have tune that keeps the converter unlocked, the converter should've locked. The mount on the transmission side (under the battery) was severely damaged, the rubber legs inside the bushing were torn through and was allowing a lot of engine movement. what is the protocol using AE to diagnosis torque slip. The faster it spins, the more force it provides, which causes the fluid to flow faster and harder. Basically, the fluid exits the center of the turbine and is redirected by the stator back into the impeller. You can't be sure the slipping or shuddering has anything to do with your torque converter until you check your fluid levels.
