I just put a fresh 4l80e in and have about 100 miles on it, i noticed a couple of times the it seemed to "glide" into gear under full load (turbo car approx 500-550rwhp) all of the sudden it stopped pulling in 4th and then very shortly after in third. when i pulled it out the fillter looked like it was full of black silicone
(like all the way stopped up) and the wire loom on the bottom of the valve body was all gummy like the fluid was eating it up. some of it looked to be missing
( the part that was melted in my filter)

anyone ever seen anything like this? im hoping all my clutches are alright but i fear not. The amsoil fluid still looked pink and new. i just paid 1200 bucks to get this thing rebuilt
