Parts ordering.
I highly recommend using 4L60E frictions in ALL '87-'93 700R4's, Along with late "E" molded pistons in the Input Drum.
This is an "E" kit with Borg Warner frictions (Hi-Energy 3-4 clutches & 2/4 Band), Raybestos steels, Teflon pump bushing, Case bushing & molded pistons
Amazon.com: 4L60E 4L65E 4L60-E Master Overhaul...The Filter & Valve body gaskets WILL NOT work on 700R4's, But at $172 the filter & seal kit are free. And its good for a first timer to have extra seals
700R4 seal kit, TransTec has the Lip Wizard Lip seal tool included.

TransGo SK 700-JR, Their TV kit is top notch. Good accumulator bushing spring selection as well. The rest of the kit does not work well in all transmissions!
