The fluid was validated to improve durability and shift stability over the life of the transmission. 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. Another one involves hard, jerky shifts. 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. Usually three years compared to an average of only 90 days for a rebuilt transmission. The 4T40E was built at the General Motors transmission plant in Windsor, Ontario, Canada.
These prices won't last long so get yours today. Technical issues and repair guidelines These gearboxes operate with parts of different quality. The 6T40 transmission pump has polished rotor mating surfaces to ensure a constant and equal pressure. In order to keep our 6T40 Transmission at such an unbelievably low price, we need to take a deposit on your old or broken unit being sent back to us. Three planetary gear sets provide the six forward gear ratios and reverse. The symptoms are no forward gears, but the transmission still has reverse.
The transmission was used up through 2005 in many other vehicles, including the Daewoo Nubira and Lanos, the Chevrolet Malibu, the Pontiac Grand Am, the Oldmobile Alero and Cutlass, and the Saturn L-Series of vehicles. The 4T40E does not use a dipstick to measure the level of the transmission fluid. The control module receives input that monitors brake pedal usage, vehicle acceleration rate, throttle position, and even whether a trailer is connected to the vehicle. I was happy to see that they offered a transmission at such a great price with the upgrades. Then they recommend having you let the customer drive it for a couple of weeks to see if the problems go away. 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. It features clutch-to-clutch shifting, eliminating the bands used on older transmission designs.
The 6T45 differs from the 6T40 in its use of heavier-duty components, allowing it to handle engines with greater torque. These are just a few of our performance-enhancing upgrades that go into every 6T40 we sell. A is going to include alterations and upgrades designed to fix common failure problems and extend the life of the transmission. It is designed to be used in transversely mounted applications and is part of a family of transmissions that also includes the. This includes that are designed to electronically shift the transmission.
Dry New, Used, or Rebuilt: Complete Rebuild Performance Inspected For: Leaks Shifting Difficulties Vibrations Excessive Noise Temperature and Performance 6T40 Gear Ratios: 4. Freewheeling mechanisms allow accurate timing between shifts, but also take up more space and add more components to the transmission. The solenoids contain a coil of wire that when energized, creates a magnetic field. It is also all-wheel drive capable. Replacement of the forward clutch requires the removal of the transmission and complete disassembly of it.
The set of pistons consists of 5 pieces. The transmission is based on the larger , and is produced at , as well as in China. Like any other parts on your car, the transmission has a finite life span. The first-to-second upshift, however, is a freewheeling action, where the second gear clutch engages while the first gear one-way clutch spins freely. This six speed transmission is packed with features not only for increased fuel economy but also quick acceleration.
Replacement of the forward clutch also requires the removal and disassembly of the transmission. The advantages of this layout enables a shorter overall vehicle length, more interior room and lower powertrain height. What are you looking for? The facility is currently capable of producing up to 300,000 Hydra-Matic six-speed automatic transmissions annually. Posted by on Wednesday, June 5th, 2013 The is a six speed automatic transmission made by General Motors. It was a great purchase, I recommend them to anyone looking for a transmission.
And remember, the companies that re-manufacture transmissions are very easy contact. Our improved torque converter has been specifically built to address leaks, lockup, concentricity and balance. Our upgraded spec bushings have been designed to improve internal fluid control and pressures. Ford also produces a similar variant called the 6F35. A reading outside this range might indicate a problem with the solenoid.
The fact that it was used in so many different brands of automobiles means that it is likely that one will eventually show up in your shop for repairs. Updated wave plates were released for many clutches in 6T70. The 6T40 transmission is compact in size while increasing fuel economy by five percent. It is recommended that the fluid be changed every 25,000 miles. The first application of the technology is in the 2007 and , as well as the sedan and the crossover. A will include major alterations and upgrades designed to make them both stronger and more durable.
