Another fascinating article, thank you for all your effort! When you have contaminated transmission fluid that has bits of this and that in it This is an indication that you have bigger problems inside the converter or transmission. Cookie Notice To serve up a little enlightenment, let's take a spin through the torque-converter world and make some sense out of all the superstition. Cloudflare Ray ID: 7c0ed4b2fd769016 This very similar to what I experienced with my failure. if someone would have put in a used ecu ,fron a electric controlled aod. 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. (Both turbines, here colored medium blue, were bolted together into a single unit, but had different blade profiles.) Well done and thank you; this must have been an enormous amount of work. Once the clutch plate is fully engaged against the pressure plate, both must turn together at the same speed. The drive fan moves air across the blades of the driven fan (which is turned off). Filling the cylinder with pressurized oil would lock the pressure plate to the clutch plate itself, forcing the clutch and input shaft to rotate with the torus cover at engine speed. Once the clutch plate is fully engaged against the pressure plate, both must turn together at the same speed. A 5 percent slippage factor means that if the impeller is spinning 3,000 rpm, the turbine is only spinning 2,850, or 5 percent slower. Think of it as two fans facing eachother inside an enclosure. Welcome to the dark world of torque converters. The DG series transmissions were notionally three-speed automatics (although early iterations were designed to start in second gear) with a torque converter lockup clutch. As the new owner of a 92 Alante with the viscous clutch I wondered what the difference was. Because of the lack of traction and limited tires, it's not critical that a street engine launch at peak-torque rpm. It stayed there(18.24) from 60mph to 90 when I let off of it. Packard achieved that goal by treating the engagement of the lockup clutch like an automatic gear change. one of the strange quirks of these transmissions is if they are a quart or so low it will feel like the torque converter does not disengage at stop. if I'm seeing "desired TC slip" of 1020rpm at all times wouldnt that pretty much guarantee the TC would never lock?

It's also important not to undersell converter weight as a contributing factor to maximizing acceleration. The one for torque slip desired is 1020 rpm.

Doesn't seem to coincide with vehicle shifting though. iThemes is one of the Liquid Web family of brands; iThemes and Liquid Web are trademarks of Liquid Web, LLC.). Whether it will add to my working knowledge is debatable, but my brain will benefit from the workout. This sounds really great, and it is. If the engine is not running smoothly and/or delivering consistent power, it can cause fluctuation in the "Desired" versus "Actual" torque converter clutch slippage along with a surging feeling.

These torque converters allow some slippage but it should not vary much from the desired PCM value. (author diagram). If this is your first visit, be sure to check out the FAQ by clicking the link above. For one, the engine would stall every time the vehicle came to a halt with the lockup clutch engaged unless the driver shifted to neutral each time. As these vehicles age, diagnosing these issues can become more challenging. Big cars weighing over 3,300 pounds generally need a converter with more torque multiplication. U.S. Pat. I no longer monitor the forum, please either post your question or create a, I am just trying to see how the management of this company can justify ignoring, or walking away from the T43 stuff right now, I am aware of the size of the Dodge Diesel market.I for one do not care about Dodge Cummins products, I have turned so many of my customers onto EFI Live from HPT or SCT that it kills me to have to tune a TCM with one software and ECM with another. The cookies normally expire in about 10 days, and are not set at all if you do not access any password-protected content. These torque converters allow some slippage but it should not vary much from the desired PCM value. Actual shows 640 rpm in drive with the brake on. Therefore, a lockup clutch needs to be accompanied by some mechanism to selectively engage or disengage the clutch. (At present, this setting does NOT affect the payment or donation buttons that may appear on portions of the site's administrative dashboard, nor does hiding the box affect any cookies that may have already been set). That could be within the margin of error for the sensor. The torque converter is made up of five parts: 1. Achieving a true 1:1 speed relationship between the turbine and the impeller is not possible with a non-lockup torque converter since it is still a fluid coupling. Come join the discussion about diesel performance, modifications, EGR deletes, troubleshooting, lift kits, tires, wheels, maintenance, and more! Do Not Sell or Share My Personal Information -. A manufacturer's torque-converter rating is generally expressed as an rpm range. JavaScript is disabled. When you experience fluid leaks, you aren't retaining the amount of transmission fluid; the torque converter needs to transfer the power from the engine to the transmission.

Just thought I would share with everyone some recent learnings I've had with my 2010 EB Flex. I had "guessed" that it could have been a valve body issue when trying to diagnose on my own and I replaced that to no avail. I havent studied the Wilson preselectors in any great detail, but if youre curious, the applicable U.S. patents are US1404675 and US1796904. The torque converter clutch is always slipping somewhere between 5% to 95% when engaged, which depends on vehicle speed and engine load.. We discussed the information to monitor on the scan tool, there is an actual slip, desired slip, and TCC status. However, that clutch was used in a distinctly different way than was Packards. works great no real problems. Your Transmission Gear Ratio at Finish Line. 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. 2. 7.3L Power Stroke - Aftermarket & Performance. Ultramatics lockup clutch was a hydraulically operated wet clutch located within the torque converter housing, between the engine flywheel and the converter turbine. check out the. It ran pretty good. 91.234.33.200 the only readings i got was for all the electronically controlled aod. Impeller Pump The impeller pump receives the transmission fluid once it's delivered. The DG series transmissions obtained their indirect ratios with a compound planetary gearset. The valve was pushed open or closed by opposing pressures generated by a throttle-controlled valve and a centrifugal governor driven by the output shaft.

Do you want them slipping when driving? These early units operated on the same principal of using one electric fan to drive another. 3. and 5. It stays between 0 and 5 RPM when locked. Okay, so it sounds like you were able to identify a potential root cause. i called a trans shop and he had no answer,but it sounded strage to him. In Drive, the direct clutch is engaged and both bands are released, causing the input sun gear, the low sun gear (orange), the planet carrier and output shaft (light green) to turn at input shaft speed.
