This includes that are designed to electronically shift the transmission. There are over 20 different variations of the 6T40 so we have over 20 different part numbers! Malibu, Epica, Tosca, Aveo, Sonic and Equinox. At the start of production for the 2012 model year Generation 2 was introduced which is currently used in all platforms using the 6T family of transmissions. You surely will not receive that benefit from a company that solely rebuilds transmissions. On the top of everything else, experts recommend to install additional transmission radiator for the range 6Т. The 6-speed transaxle used in the Chevy front-wheel drive and all-wheel drive applications have had consistent failure of the wave plate on the 3-5 reverse clutch pack. First introduced in 2007 as part of the Chevy Captiva, everyone was impressed with the electronically controlled, all wheel drive manufacturing and its clutch to clutch shifting.
Usually three years compared to an average of only 90 days for a rebuilt transmission. Thanks for reading and we hope this information was just as helpful as the other 2 parts of this 4 part series. The factory recommends that you re-program the computer up to three times in a row to get the problem to stop. Posted by on Wednesday, June 5th, 2013 The is a six speed automatic transmission made by General Motors. Then they recommend having you let the customer drive it for a couple of weeks to see if the problems go away.
We have 2 locations one in Willow Grove and one in Lansdale to serve you. So what does a No Hassle Warranty really mean? A properly working solenoid will usually return a reading somewhere between 20 — 30 ohms. It determines an inflection event at a torque path that comprises the hydraulic clutch return spring force. This magnetic field then moves a plunger that is attached to a valve in the valve body. Every transmission is cold and hot tested before shipment. It is also all-wheel drive capable.
We will be finishing the last part of this series next week and it will inlcude some extremely vital and more important info for the 6T40 transmission. To comment on a part of the text, you can select a part of the text with your mouse - and then the comment options will appear allowing you to also share a part of the text on social network pages. Are you looking for 6T40 transmission troubleshooting help, 6T40 rebuilding tips, 6T40 technical service bulletins, 6T40 diagnostics or technical information? It was first introduced in the 2007 Chevy Captiva followed by the Malibu in 2008 and quickly spread to the compact, mid-size, and small crossover vehicle line. As the federal government pushes for higher fuel mileage numbers from the manufacturers we will see an increase in the number of gear ratios and consequently see an increase in the amount of failures as parts become smaller in order to fit more components in the same given dimensional space that occupied four gear ratios. This is a normal condition and no repair attempts should be performed.
This video describes some of the inherent failure points of the General Motors 6-speed transaxle. Possible cause: One of the issues include taking higher rpms, many times over 3000 rpms, to shift between gears 1 st and 2 nd gear, and 2 nd and 3 rd gear. Whether you need 6T40 wiring diagram information, 6T40 transmission rebuilders tips, 6T40 technical information, 6T40 diagnostics, 6T40 troubleshooting help, or just answers to your 6T40 transmission rebuilders question, the is the place to go! Possible cause: This transmission is very advanced and full of electronics. The 6T40 is also found in hybrid vehicles. Connect the lead from your ohm meter to the two wires coming off the solenoid. Gen 1 and 2 line pressure specification tables are provided in Figure 8. Working on A 6T40 Transmission? This video shows this failure in both the 6t70 transmission and the 6t45 transmission.
The wire has a tendency to either completely break or internally short out. Specifications were taken from a 2013 factory repair manual. Both are good options but the best option for you depends on the transmission problem, the year, make and model of vehicle, the mileage and the vehicle value. A reading outside this range might indicate a problem with the solenoid. It consists primarily of a four element torque converter, three planetary gear sets, five clutch packs, one mechanical one-way clutch and a hydraulic pressurization and control system.
There are reports of this helping to cure the symptoms. A is going to include alterations and upgrades designed to fix common failure problems and extend the life of the transmission. It is also recommended to keep a wary eye on symptoms of the pressure loss in the line after a long-term operation as well as check and clean the valve body with solenoids. Overloading with high torques and aggressive accelerations may have a bad impact on the gearbox. Applies a pressure pulse to a hydraulic clutch when it is in a disengaged state Figure 10. At the start of production for the 2012 model year, Generation 2 was introduced which is currently used in all platforms using the 6T family of transmissions.
If a solenoid is found to be defective, they are easily replaced and fairly inexpensive. Three planetary gear sets provide the six forward gear ratios and reverse. Many times, this is caused by excessive heat in the transmission. It is also all-wheel drive capable. In case of oil overheating it is often required to change all pistons because the rubber gets hard under the influence of the temperature. In addition, it was used in.
Each company named and manufacture the transmission separately. Technical issues and repair guidelines These gearboxes operate with parts of different quality. These pressure switches were originally used Gen 1 to monitor clutch operation via the solenoids and regulator valves for adaptation purposes. R emanufactured transmissions carry a longer, 3 year, nationwide warranty with additional upgrades while a rebuilt unit generally carries up to a 1 or 2 year warranty and upgrades vary from shop to shop.
