Lock up converter

A torque converter is a type of fluid coupling which transfers rotating power. This video covers the differences between lock - up and non lock - up torque converters, the anatomy of lock - up torque converters, and the advantages of using a lock - up converter. The latest innovation from Neal Chance Racing Converters is the Full Billet Internal Lock Up Racing Converter. This unique new converter was a top secret joint project between NCRC and Rossler Racing Transmissions, but the cat is out of the bag now! The torque converter acts like a mechanical clutch, allowing the load to be separated from the power source.

This “donut” converts fluid pressure to lock the converter output shaft, thus transferring the engines power and torque to the driveshaft.

At approximately mph, connect the other end of the test light or jumper wire to terminal F at the ALDL. I am familiar with the general workings of a torque converter. The engine-side blade pushes the flui the fluid spins the transmission-side blade. Torque Converter Lock up Kits. Guided Navigation Display Options.

This later version had an electronic lock-up converter to increase fuel-efficiency at cruising speeds. The TH350-C lockup version can be identified by an electrical plug on the left side of the transmission.

Lock up will do you no good in racing, however a significant portion of your fuel savings on the highway is because of lock - up used with the OD. OD without lock - up tends to make a lot of heat in the torque converter. B)fuse holder, (C)oil pressure switch and lighted manual switch. Your kit contents could vary. Oil pressure switch in the 4th gear port.

Fuse holder, manual switch, oil switch, lock - up plug Fig. This eliminates the need for a manual switch. When retrofitted into early muscle cars, these trannys require the pressure switch to be changed and a few wires rerouted. It bolts directly to the flexplate, which in turn bolts directly to the crankshaft. RLock up Kit Complete Relay.

This kit will complete the lock up system of the torque converter , which will automatically lock up in fourth gear. It will work in any vehicle that has operational b. BM converter lockup controls provide dash-mounted control to govern converter lockup at any speed between and mph. An LED display tells whether the converter is locked or unlocked.

When a lock up converter is use it locks at whatever speed is programmed into the chip. It should unlock whenever one lets off the gas, or touches the brake.

It also normally unlocks when one accelerates sharply, or, at wide open throttle. On a Ford and I use that because its what I know and most work the same way. The converter and shifts are load based.

It can be a learend stratigy also, when the trans starts to fail it might learn to add more pressure to lock a gear up or shift timing change.

The unlock solenoid on the valve body built up or released pressure on the piston to lock or unlock the torque converter. When the TCC solenoid receives a signal from the engine control module (ECM), it opens a passage in the valve body and hydraulic fluid applies the TCC. When the ECM signal stops, the solenoid closes the valve and pressure is vente causing the TCC to disengage. This lets the torque converter lock in gear or unlock out of gear.

Dummy or non locking converters never lock up and are therefore a constant source of heat than must be effectively dealt with. Third: Lowering the engine RPM while driving at highway speeds is the very goal of overdrive gearing but this can easily drop the engine RPM below the effective coupling speed of the torque converter. BM Converter Lock - Up Controllers Show Product Info For use on GM transmissions, these converter lock - up controllers prevent converter lock , unlocks cycling and governs lock - up at speeds ranging between and mph. Designed to eliminate premature, unwanted converter lockup so you can avoid engine lugging and spark knock.

The lock - up torque converters that are being designed for racing today incorporate a multiple disc clutch pack within the converter that is applied hydraulically to lock the converter up. The Quick Lock torque converter drive unit provides the means to control the hydraulic apply of the lock - up clutch pack. SELF-CONTAINED within the transmission, and requires a simple single wire 12-volt input through our custom case connector. Racers can now have the best of both worlds… the torque multiplying advantages of a torque converter with the efficiency of a clutch, and all in the lighter weight lower drag.

The 700-R4’s 500-rpm-stall converter wouldn’t lock up , resulting in excessively high rpm and reduced mileage at freeway speeds. Although the rod was spirited around town, highway driving was. Our converters are made from the best materials available and are on the cutting edge of converter technology. We are constantly researching and testing to stay on top!

BM’s Converter Lock - Up Control provides driver control of the speed where converter clutch lock - up takes place. Racecars use non lock up converters. Street cars use a lock up converter.

Lock up converters producle less heat because the internal slippage goes away when locke and most are locked in 3rd and 4th gear, depending on model year. They refer to this application of clutches as lock - up. Often this problem is mis-diagnosed and sometimes they needlessly rebuild transmissions as a result.

I just wanted to let you know how thrilled I am with the Stallion converter. It is a refreshing change to buy a product that completely lives up to its billing. Everyone with an AOD should buy one. Re: Lockup torque converter for a TH400?

PM BM offers two different kits to lock up the converter at a preset speed that is able to be determined by you and is very easy to install. Any torque converter clutch sensor malfunction will prevent a torque converter from locking up. When a torque converter couples, the one way clutch free spins. A sudden drop in mpg in addition to a decrease in top speed could indicate an internal torque converter failure. Check here for special coupons and promotions.

I think it is loosely based on a Bruno drive, but it is billet and has a lock up option. Pretty trick piece from what I have seen.
