The valve body ***** are easy, I mark each one with a scratch awl. Even better are the books offered that show the location of EVERY check ball in every transmission. AVG or AWG I can't remember offers this manual for the princely sum of $19. The forwards burn mostly due to valve body leakage, solenoid failure, lack of COOLING. Do yourself a real favor, google super cooling kits for E4OD. simple to install, DIY kits are cheap and double the flow of fluid through the cooler. Which better be new or you are gonna eat that repair very quickly. DO not be afraid, that thing is easily repaired as long as you follow the written instructions from any one of a dozen sources. One last tip, Sonnax.com, go there.
