On this video we go through the re assembly of a 4L60E Transmission. I tried to make this video shorter for you so I skipped the bushing installation and installing the bolts on the valve body. But you can go to the teardown video for reference on where each bolt goes, since they're different sizes. I will make a follow up video on bushing installation.

On this video we can see the disassembly of a 2006 4L60E transmission. The most common failure on these units is 3rd. clutch burn up, the reaction sun shell and the 2-4 band. Failure on these transmissions is not necessary the way it is treated, rather is these common or pattern failures. Valve body ware is also another issue and can be corrected installing a correction kit of your choice.
