We loaded the software, but we found it easier to calibrate using the handheld interface. If a decision has to be made to replace the transmission, I highly recommend you consider a as your first choice. We also added a set of Wilwood front disc brakes because the Rat promised enough power to demand equal stopping performance. Are you looking for 5L40E transmission troubleshooting help, 5L40E rebuilding tips, 5L40E technical service bulletins or technical information? Failure to address this problem once it evolves could lead to the total failure of the transmission. But if all you are looking for is a basic system, making the connections to make the trans work is pretty simple.
The performance world is changing. To me, I see that as a retarded way to engineer failure. I ended up getting a rebuilt transmission at the end of 2012. Click the icon to leave your comment. Simple Shift is the latest breakthrough in electronic overdrive transmission control. I found there is a pair of wires which goes to the pressure control solenoid so it should be easy to modify that signal for that matter, any of the clutches! As with most of the controllers, it also incorporates Manutronic connections capable of driving paddle shifters such as the shifter offered by Twist Machine. Final drive ratios include 2.
Like the other systems, the Painless Torc offers two different shift calibrations. The 5L40E unit's centerpiece is an automatic overdrive which supersedes the French-made 4L30E four-speed automatic light-duty gearboxes, and like them features a torque converter clutch to eliminate slipping losses in select forward ranges. The pump stator valve is also replaced quite often. We have an option to reprogram our 6 speed transmissions prior to shipping, when ordering let us know what your are installing the transmission in. The only other systems that offered that kind of precise control were the laptop-driven programs.
This is less of a disclaimer as it is an acknowledgement of the physical capabilities of the transmission. Unfortunately, a leaking pump seal would require the removal of the transmission to remedy. The electronically controlled transmission is designed around a fully articulated Ravigneaux gearset that is controlled by electronically timed application of several range-specific hydraulic clutches, in combination with mechanical one-way sprag clutches. It is a trigger for car owners to change oil and solenoids avoiding the valve body wear-out. Do you just have 5L40E questions and need some answers? Could I use two MicroSquirts, one running the engine and one running the transmission? The torque converter transmits dirt to the transmission by means of worn-out clutch of the valve lock-up. Now it can engage at 50 kph 31 mph instead of 90 kph. And once you have a shift program you like, there will be very few reasons to ever change it.
The is the place where the industries best transmission rebuilders work together to help solve the most complex automatic transmission problems. Of course, if you want to go further into the setup, the handheld controller allows you to modify shift aggressiveness, shift firmness, and minimum speed for torque-converter clutch lockup. But maximum rpm is the point at which the transmission begins the shift process. Allow up to 8 weeks for rebate processing. What kind of warranty coverage are you looking for? The easiest way to check for this problem is to remove the sump and check for debris. That combination worked to prevent the engine temp from exceeding 195 degrees F.
After we talked with the controller manufacturers, one point became very clear: The controller is not a magic fix for a weak transmission. Allow up to 8 weeks for rebate processing. In order to maximize transmission life, obviously reducing or eliminating clutch slip would make sense. The shaft is connected to a drum inside the transmission, and as the drum is at the back of the gearbox, not only do you need to remove the transmission to replace it but you also need to take all of the guts out of the gearbox to get to it! This is all possible because of the sensors present in these newer transmissions. But that takes nothing away from its overall performance and excellent adjustability. Because of this, shift points are estimated based on vehicle speed. The only thing preventing this controller from making the top of our list is the absence of a data-logging feature.
As such, it is subject to the typical electronic transmission failures. My car has around 180k miles on it. All parameters are simply adjusted with easy-to-use dials on the end of the Simple Shift unit. When it was new, it was the world's fastest diesel car and most efficient luxury car. The only way to know for sure was to put them to the test. During our testing, we set the car up for quick-change electrical connections and had each box running in less than half an hour.
The problem is I don't like how it shifts so smooth. For most motorists, however, nothing less than a full rebuild and replacement converter will remedy the problem. If you already own a vehicle with this transmission, keep the above information in mind and try to catch the problems before they destroy the transmission. It was underrated when used in combination of M57D30 engines. No laptops or hand-held tuning devices are required to completely control shift points, shift firmness, and torque convertor lockup.
Transmission Computer: Our Test Mule Your hub for horsepower Get first access to hit shows like Roadkill and Dirt Every Day Join free for 14 days now The best way to test these controllers was to bolt them all in the same car and evaluate their performance. Dial it up a notch! The best way to control an automatic transmission is to use one of the new, electronically controlled overdrive gearboxes Transmission Computer. . Are you looking for 5L40E transmission troubleshooting help, 5L40E rebuilding tips, 5L40E technical service bulletins, 5L40E diagnostics or technical information? We completed the exhaust with a great-sounding, 2. For example, you could have calibration A set up with a performance orientation with aggressive upshift speeds and higher line pressures, while calibration B could be used for towing or light-duty daily driving applications. Even with our experience with the previous controllers, it took a little longer to tune the trans to our satisfaction.
