Replacing the planetary carriers requires a full teardown. Although some builders and highly experienced hobbyists may make their own modifications in conjunction with certain shift kits, such as using custom separator-plate hole sizes or disabling accumulators, doing so is not recommended. Instead, I will go over general guidelines for shift-kit installation, and helpful tips and procedures to make the process easier. Always replace the boost valve as they are always worn. It is not uncommon to see the steel balls stuck, or even pushed clear through the steel plate. The main difference between the two is that the 4L60E is a full electronically controlled transmission while the 700R4 is not.
Keep an open line of communication with your mechanic because you are going to need it. If you do it yourself make sure you have parts for your particular transmission.

The contents of each bag should be kept together during the shift-kit installation process. Watch out for the neck snapping shifts! They also have diagrams of the transmission case and separator plate and valve body, pointing out check-ball locations.
They do so by controlling the flow rate, pressure, and timing to the various components of the transmission. If you plan to using the transmission in a street car or towing vehicle than I recommend you go with a high quality shift improver kit. Another aspect to note is the transmission cooler lines. You will also want them to be machined from a piece of billet instead of ones that were cast.

It is very easy to forget this little ball and spring, but it tends to get gummy and starts sticking. Upgrading to the 5-pinion unit offers the ability to hold much higher torque values. If the telltale signs are there, things such as a burning smell, leaks, trouble shifting gears, etc. However, the price can go through the roof for a brand new transmission. Now route the cable from under the vehicle into the inside without letting it drag the ground. A rebuilt transmission will not include this feature.

You can go with a rebuilt transmissions or one that was re-manufactured. Oil pressure coming up through the input shaft pushes the apply piston forward.
Some shift kits recommend disabling accumulators, or blocking oil flow to them. Finding one used can be the most economical options, especially if you are going to do all of the work yourself.
