The Transgo SK 4L60E shift kit is a comprehensive package that provides everything you need to upgrade your transmission's performance and reliability. The kit includes a new valve body, aux valve body, 1-2 accumulator, TCC solenoid, speedo housing bracket, magnetic base, and vise grips.

When installing the kit, it's essential to follow the proper procedures and use the right tools. You can find detailed step-by-step instructions in the Transgo manual or online resources. Additionally, it's crucial to torque fasteners to the required specification to ensure a secure installation.

You can purchase the necessary hardware and tools from various sources such as Bay, Hardware stores, Amazon, Snap On, Cornwell, Matco, etc.

The Transgo SK 4L60E shift kit is designed for 3rd generation valve bodies found in F-bodies and Corvettes only. However, it's not applicable to other transmission models or years. The third design drum will technically retro to any year 700R4 but may result in harsh engagements into drive if installed on non-aux valve body applications.

The kit includes a new forward drum (097 last three digits of casting) that is designed specifically for the aux valve body case. It's essential to note that this design will not interchange onto a non-aux valve body case and should only be installed on all years of 700R4 transmissions.

One of the key features of the Transgo SK 4L60E shift kit is its ability to provide 100% mechanical control of the torque converter clutch. The kit takes three check balls, including one in the 'bathtub' for low reverse. It's also recommended for anyone seeking improved transmission performance and reliability.

The kit can be retrofitted onto all prior years of 700R4 transmissions as a service pack (pump assembly and forward drum) and is strongly recommended for any 1982-E1984 700R4 transmission. This is because the first generation valve body has a bore for mechanical TCC command/lock-up, which can cause issues if not upgraded.

The updated forward drum housing features an improved 3-4 apply circuit bleeder checkball capsule (152 last three digits of casting no). Additionally, the kit includes a wider pump stator to accommodate the second design input shaft. However, these parts should be discarded if working on a 1982-E1984 unit and replaced with L84-1986 pump/input drum assemblies.

The first design forward drum has a poorly designed 3-4 clutch bleed orifice (368 last three digits of casting no), which can cause issues during transmission operation. The kit also includes a 7-element forward roller clutch assembly (Jan 1-May 31, 1982).

By following the proper installation procedures and using the right tools, you can ensure a successful upgrade with the Transgo SK 4L60E shift kit. With its comprehensive design and improved features, this kit is an excellent choice for anyone looking to improve their transmission's performance and reliability.
