i just got my new tranny in and it needs to be flushed to get all the crap outa the cooler,lines etc. i was wonderin what would be the best way to go about this and which line is the supply/return. the reman trans came with an inline filter but i wanna get as much of that crap out as i can.

 

The time to flush the coolers is BEFORE installing the new trans.

On an E4OD/4R100 the front line at the trans is to the cooler, the rear is from the cooler. I never can remember on the AOD/4R70W whether the top or bottom line is to the cooler.

 

yeah i just installed it,lot of good that did. screw it i'm puttin the filter on and hopefully that'll clean it out
