4r100 trans

[Mr.Runner]

hello there. truck is a '03 f250 with 5.4L gasser. 170 *** kms

tranny seems to be slipping. when its cold it holds great. but when it warms up it starts slipping. but weird thing is i can still do a brake stand when trans is warm. so i was think that diode that ford changed?

what do you guys think?

go to the ford dealer, they can tell you if that one had a bad diode problem----could need a reflash of the pcm also----
