My transmission is slipping once I a while. I just had it rebuilt by aamco transmission. They ate telling me that the computer is saying it is a range or neutral switch. How much do they cost and where is it located on the transmission? They want less than $100 is what they told me. I have 2001 f150 4x4 5.4v8

 

I ran into this sight seaching for an answer, maybe they can help. http://www.monstertrans.com/store/
