The version, which followed shortly thereafter, was known as the Super-Turbine 400. Find out more about your Turbo 400 transmission and how to identify it below. The 4L70E transmission is the same as a 4L65E with a speed sensor located in the pump. This is a durable and very well-known transmission, as it was in production for many years and applied to a wide variety of vehicles, not only General Motors. The Torque-Drive is a Manual shifted Powerglide on the column. It was developed jointly by Buick and Chevrolet to replace the two-speed Super Turbine 300 and aluminum case Powerglide transmissions.
The 4L60 got the E at the end whenever control of the transmission was switched to the engine computer. The L denotes that the transmission is longitudinally positioned. Five-pinion planetaries, along with a strength-improved output shaft, were improved to withstand the 300+ lb·ft 400+ N·m of torque of the 6. It is machined into the transmission in most cases. Later models used a circular style iron adapter which is generally considered the stronger of the two. This version tilted the transmission about 4 degrees in order to better accommodate the transfer case. You can now jump down to the year identification guide.
There is no difference other than the name. This transmission eventually made its way into many of the truck applications for General Motors. The transmission and module are assembled together, so no additional steps are necessary during vehicle assembly. This 3 speed transmission has its gear ratios defined as 2. For the purposes of easy identification, I have broken the 4L60E into 4 distinct eras. As you disassemble your transmission, make note of any obvious wear to parts that may need replacing. Overall the transmission remained in production an impressive 27 years before it was eventually replaced by a 4 speed electronically controlled transmission, the 4L80E, in 1991.
However, this transmission was notorious for its failure rate when used behind too large an engine - the largest displacement being the Oldsmobile 5. The transmission should be serviced every 20,000 miles or sooner, depending on how much you tow with it. This level is for the enthusiast who wants the hardest, quickest possible shift. The shortest being used with the 203 transfer case. Switch-pitch Turbo 400s also had two electrical connectors where the non-switch-pitch Turbo 400s only have one electrical connector. It is part of the family of.
If you're not familiar with this, the first part of the video covers this and more. That being said, a common fill volume is between 11-12 quarts for a stock transmission. It is very easy to read. This transmission was produced by General Motors, but is also sometimes known by the name Hydramatic. Four wheel drive truck applications used 3 various shorter output shafts that coupled with a female transfer case input shaft.
This transmission does vary in the amount of fluid required, based on certain specifications such as which torque converter is used. It was eventually replaced by the 4L80E. It was not only used in General Motors applications, but was also used for many luxury cars. This is almost always cause by the vacuum line that runs to the modulator from the intake manifold. Every automatic transmission will need a universal clutch spring compressor as well as snap ring pliers and pic sets for removing valve guides.
This allows the transmission to be tailored for optimal fuel economy while delivering excellent acceleration traits. This transmission does vary in the amount of fluid required, based on certain specifications such as which torque converter is used. The 4 indicates that it is a 4-speed transmission. This weakness can be addressed by using an inexpensive aftermarket case saver kit. The amount of torque that this can handle will vary based on year of production, but that the max engine torque is 350 lb-ft with a max gearbox torque of 650 lb-ft. The Th400 has a much more complex pan then the Th350. The 4L60E transmission is both the physical and spiritual successor to the.
These can be identified outside the vehicle with the torque converter removed by a narrow front pump spline. The Turbo 400 is compatible with most Jeeps. Pickup trucks are probably some of the most abused vehicles on the planet, with owners often towing or carrying payloads above the factory limit. This was one of General Motors editions of the Hydramatic transmission series. There was constant improvement, and by 1987 this transmission was much more robust and reliable. You will also want to invest in a.
Another important fact is that organic transmissions fluids can start to turn to a varnish at temperatures as low as 240 degrees. Electronic safeguards prevent over-revving should the wrong gear position be accidentally selected. Some areas are cast iron, such as the center support for the transmission. The 4L60E uses computer control to shift. The 4L60E was utilized in cars and light duty trucks. Before you get started rebuilding your transmission, you'll need a few parts and tools.
