A) Disconnecting the torque converter from the engine at a stop B) Allowing quicker starts in first gear C) Eliminating converter slippage D) None of these You may experience just one of these symptoms or all three. The torque converter is located in between the engine and the transmission. Relying on lock-up to keep your torque converter and transmission safe is a bad idea. When i am at a complete stop and go to hit the gas the front end of my car shudders until i lighten up off the gas. The truck is a 4.8 with a TB converter currently, LS HotCam 4.11 gear 4l60e. Once these signs are evident, it is needful to get the unit fixed or rely on the expertise of a professional. That’s why a damaged torque converter is often confused with faulty transmissions, as the two have similar problems. I did the trans relearn today with the ***** 275 tune. A bad torque converter’s symptoms are shuddering, overheating, slipping, contaminated transmission fluid, unusual sounds, and an increase in stall speed. I started this about torque converter slippage. Torque converter performance isn’t just about stall speed; it’s also about how firm a converter hooks up when it does stall. If any of these occur, the converter needs to be replaced as soon as possible. For the converter clutch to … There is a flex plate in this area where the torque converter is installed onto. The TCC System uses a solenoid-operated valve to couple the engine flywheel to the output shaft of the transmission through the torque converter. The equivalent location in a manual … I changed to the ***** V2 a few weeks ago. 2018 JLR 2.0 eTorque. Hi all. I was running the KEM 250 and 310 tunes. Torque Converter slippage (Help) GringoPete. Have a question on gearing. ATI builds torque converters using all new components, unlike other torque converter … Mine seems to lock-up somewhere in the middle of 3rd gear, but is only really noticeable at part throttle, or when accelerating after non-complete stops. At first i thought it was my worn tires which i replaced but it is still doing it. But the ‘slippage’ that the OE engineers came up with was a ‘controlled slippage.’ And in fact, the ‘slippage’ that they designed technically wasn’t slippage at all. If your torque converter is going bad, there are normally three pieces of evidence that could pop up—transmission slippage, dirty transmission fluid, and shuddering at low speeds. 1,676 Posts . These pieces work together in … Torque Converter slippage. When your Ford F150 torque converter malfunctions, the truck experiences shuddering, delayed shifting and transmission slippage. Torque converter slippage is important during acceleration, but it becomes a liability once the vehicle reaches cruising speed. Thank you, if I had a manual transmission, good clutch, my car would run 60mph @ 3,000rpm. The blade assembly inside of a torque converter controls the flow of transmission fluid. Discussion Starter • #1 • Jun 16, 2013. The impeller is a piece with tilted blades that look somewhat like a fan. They need to have my converter to be able to set it for my car. This flow produces a maximum torque increase of 2:1 when the turbine is stalled. The purpose of the lockup clutch is to directly connect the engine and the transmission once slippage is no longer needed. Since the focus has now shifted massively to fuel consumption and CO2 emission, vibration damping through high levels of slippage and over wide speed ranges is no longer appropriate. This RPM point is called the stall RPM, and it is determined by two factors: the power (torque) that the engine can deliver at that RPM, and the converter slippage. This means having a full understanding of the peak torque of your engine provides the knowledge of which converter will be most efficient, allowing you to increase track speed. I am beginning to wonder if I have too much torque converter slippage or the place I had put my ring and pinion in did not put the 3.42 in that I requested. I have a log attached. It was actually the rapid fire action of turning on (applying) and off (releasing) the torque converter clutch. torque converter slippage in the critical lower speed ranges, so the torsion damper in the torque converter did not need to cover these speed ranges. i have put a new transmission, and swapped from my FTI 3200 converter to a TB converter, trying to … This is known as a tight or loose converter. Once the crankshaft moves, the flex plate spins and allows the conversion of the torque energy from the engine to the transmission to take place. Lockup reduces slippage in the converter increasing fuel economy. And this multiplication enables the fluid from the turbine’s curved vanes to deflect off the stator. Shifting Symptoms Another symptom of lowered pressure output from the converter is a tendency to have soft, or delayed shifts. The lock-up clutch, a rigid connection between the impeller and the turbine rotor, ensures that the slippage of the hydrodynamic operation is eliminated and that engine power is transmitted to the drive train without any loss. I never saw a problem with the converter, it never went over 3 to 4 RPM slippage at WOT with it locked. Anywhere racers can use a torque converter you’ll find a Neal Chance Converter Customer winning rounds, setting records and taking home championships. Torque converters from ZF feature optimum hydrodynamic efficiency. It ran pretty good. Our high gear mph went from 120 to 146. Somewhere some missed my response about contacting Hughes and their response about retuning the converter and they could fix it. 57 Posts . The torque converter clutch increases efficiency by _____. A torque converter is typically made of four major components: an impeller, a stator, a turbine, and a clutch plate. The previous chassis dyno numbers were hindered by a slipping torque converter, but the new setup shows great potential with only 9.612 percent converter slip. Things that can damage a device include a degraded torque converter clutch, a damaged torque converter seal, faulty needle bearings, and damaged torque converter clutch solenoid. hello all, i have a converter slippage issue, i feel like it is in my tune because i can play with the unlock/ lock button in my Scanner, it will lock briefly but then slip. The torque converter is designed so the fluid flows from the impeller to the turbine then back to the impeller through the stator. Torque converter problems can be avoided when you know the symptoms to look out for. Does anyone else experience torque converter slippage on part throttle 1-2 & 2-3 shifts? Discussion Starter • #1 • Oct 23, 2012. A torque converter is a type of fluid coupling which transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load.In a vehicle with an automatic transmission, the torque converter connects the power source to the load.It is usually located between the engine's flexplate and the transmission. While torque multiplication increases the torque at the turbine output shaft, it also increases slippage inside the converter, raising the … This is because a torque converter controls hydraulics, and if it’s bad, it won’t allow enough pressure to go to the transmission and this causes the car to accelerate poorly. In the olden days you wanted to lower stall to reduce the heat buildup from the slippage in the converter. Our racing torque converter customers have broken records and won numerous events and championships in NHRA, IHRA & NMCA drag racing! Your Car Doesn’t Shift Gears Easily. Therefore, slippage is reduced and heat within the converter increases. Slippage can also occur if the converter clutch fails to engage fully, leaving only the fluid-coupling effect, which is inherently inefficient. When enough torque is developed by the engine and the converter, the turbine begins to rotate and turns the transmission input shaft. Does anyone here know anything about "Torque Converter Slippage"? With gear slippage, you may also feel a loss of acceleration. Since the clutch locks the engine and the transmission into a direct drive, as a result, a bad clutch can become unpredictable when locking the transmission and engine. A torque converter has the major characteristic of multiplying torque if the output rotational speed is low. There are four main parts to a converter – the turbine, the pump, the stator, and the front cover. 04-16-2008, 08:37 AM. A torque converter is designed to transfer the torque produced by the engine, and convert that into usable power to be applied to the ground through the transmission, rear-end gears, and ultimately the tires. Without the Torque Converter Clutch the converters slipped all the time, and it was easy to overheat the transmission. The stator is what makes a torque converter a torque converter; without the stator, it's just the fluid coupling. That's why virtually all modern torque converters use a lock-up clutch. The torque converter does this for you, allowing you to move between different gears from the engine to the transmission. As the torque converter locks up to keep all that unnecessary slippage and heat at bay, it now has to overcome even more slippage than usual, which taxes the lock-up clutch even more, and can significantly shorten the life of the converter. 3. Torque converters from ATI are custom built high performance, racing converters for drag race and street use for GM, Chevrolet, Ford and Chrysler applications. The early designs of the torque converter caused an RPM slippage of fluid between its turbine and impeller. Torque converter manufacturers like B&M, TCI Automotive, and Performance Automatic employ techniques that make torque converters more efficient with less slippage. The symptoms of a bad torque converter clutch include engine stalling, poor gas mileage, and slippage. Torque converters are comprised of five main components: the impeller, the turbine, the stator, a clutch, and the fluid.
