yes i did Dual Feed the Direct. i am wondering if i have the correct reverse band with the correct drum, i read about smooth and coarse drum as to thats why some bands have the grooves in the fiber and others do not, I am fairly confident that i burned up the forward clutches because i had installed the Wrong Oring on the input shaft i put to thick of a oring on and the converter never seated into the pump. I am going to follow the advice i have read on these posts, and from learning about the CK performance instructions and leave out the #5,6 check balls because i am going to do a accumulator delete, and also remove reverse check ball for faster reverse engagement, which means i think i will remove the trans mission again. i just recieved my trans pressure checker so i will be able to check the pressure, i think i will check it for the experience and see what it is doing pressure wise in there.
i did not go the boost kit, and i ground down the reverse boost land on the valve, cross drilled for bleed off, i think i did the standard procedures, enlarged drain back for converter,
i have a TH400 that i had built years ago with a shift kit ran it behind my 520 cadillac and it would snap gears when shifting, so when i read that these mods on the 4l80 would cause some snappy shifts i was looking forward to it, BUT i did not notice any difference in shfting force, i drove my first attempt rebuild 4l80 with full manual mods sereval thousand miles with no majot issues that i was aware of., but i did leave the center seal on the dierect and forward drum with the dual feed so i took out the tranny to remove the seals and see some improvement, i created these problems this time because i wasnt satisfied with the shifts and 1st didnt feel like it was biting {possible i had been starting out in second} and thus the can of learning worms has been released upon myself, i almost feel like i asked my mom a question, i really didnt want to know that much about it it, but it is time to learn
