Hi guys. R. J. here. I need to replace my safety netrural switch. I have a new OEM one on hand. One tranny shop said that they would do it for $80. So off I went.When they put my truck on the lift they then told me that they would not do the work so I want to do it myself. I've wathed some videos. None go into enough detail. Do I need to remove the left cat to get to it. Do I need to drop the pan. One guy said I do another said I don't. Once on does it need aligned. Do I need to lower the tranny a bit.
