I have the 1-2 shift hunt on my truck and am considering replacing these two parts. I have read my old service manual on the 47re and feel confident that i can do this. However, I do not know if the info I have read is the same for the 48re. I really don't feel like paying the stealership $187 bucks just to look at the transmission and tell me what I already know. Have any of you fellas out there done this and if so how much is involved.
